This study investigated the phytochemical constituents and antibacterial activities of two medicinal Vitaceae species, namely: Cayratia trifolia and Tetrastigma harmandii. The growing environment (location, elevation, soil properties, and associated plants) of the species in northeastern Cagayan, Luzon, Philippines, were assessed and leaf samples were collected for phytochemical screening and antibacterial analysis. T. harmandii dominated the population found growing in various habitats such as hills, residential areas, near coastal areas and island shorelines, nipa plantations, agricultural and grasslands, near bodies of water, caves, and secondary growth forests while C. trifolia were only found growing in swamps, hills, and secondary growth forests. Both plants were found climbing in plant species like ipil-ipil (Leucaena leucocephala) and kakawate (Gliciridia sepium). T. harmandii populations were growing in soils with lower soil pH and higher nutrient content as compared to C. trifolia populations which grew in soils with higher pH and lower nutrients. Antioxidant properties were exhibited by the presence of secondary metabolites. Alkaloids, flavonoids, phenols, terpenoids, anthocyanins, tannins, and saponins were detected in C. trifolia ethanolic leaf extracts while phenols, terpenoids, tannins, and saponins were detected in T. harmandii. Both species showed inhibitory activity against Staphylococcus aureus. In addition, a slight activity against Klebsiella aerogenes was observed for T. harmandii. Thus, C. trifolia and T. harmandii also have antibacterial properties.","PeriodicalId":17638,"journal":{"name":"Journal of Tropical Life Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45051971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hamiguitan Range Wildlife Sanctuary and grown in the Central Mindanao University Garden to monitor the growth and development of the species. Unique morpho-anatomical features include sparingly branched glabrous stem with spirally-arranged reddish terminal leaves crowded at the apical part, paired persistent stipules, anomocytic stomata, without glandular hairs and with leptocentric bundles in the petiole. The inflorescence is likewise unique, being enclosed to form a syconium (fig) which occurs in pairs and axillary. The flowers are imperfect with the staminate flowers situated the osteole while the pistillate flowers are at the syconia's interior and pollinated by agaonid wasps. The seeds germinated after four days of sowing, and syconia were formed after 365 days exhibiting several stages of development. These morphological and developmental characteristics are important in mass propagating this endemic plant for its medicinal and food uses.","PeriodicalId":17638,"journal":{"name":"Journal of Tropical Life Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42038939","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research aimed to investigate the effect of single bulb garlic extract (SBGE) on the pro-inflammatory cytokines TNF-α (CD11bTNF-α) and IL-1b (CD11bIL-1b) in the spleen, spleen weight, and TNFα secretion in HFD mice. Twenty-four mice were divided into six groups: normal (healthy mice); HFD (HFD mice without any treatment); HFD + Simvastatin (HFD mice receiving simvastatin); HFD + SBGE 100; HFD + SBGE 200; and HFD + SBGE 400 (HFD mice receiving 100, 200, and 400 mg/kg BW of SBGE for 4 weeks). Blood serum was collected at the end of treatment, and macrophage was isolated from the spleen. The relative number of CD11bTNF-α and CD11bIL-1b were examined using flow cytometry. SBGE treatment significantly (p<0.05) reduced the spleen weight and the relative number of CD11bTNF-α and CD11bIL-1b in the spleen of HFD mice. SBGE treatment also prevents the elevation of TNFα levels in the blood serum.

No comprehensive studies with photographic evidence on Phylloscopus have been conducted so far in the Southern parts of West Bengal, including Bankura district in India. Three types of habitats of Gangajalghati village in Bankura district were surveyed during winter for 8 months between November 2015 and February 2017 and bird counts were recorded and photographed. A total of 49 individuals from four species of Phylloscopus were recorded. The most abundant species recorded in the study was the dusky warbler (Phylloscopus fuscatus, Blyth, 1842) followed by greenish warbler (Phylloscopus trochiloides, Sundevall, 1837), common chiffchaff (Phylloscopus collybita, Vieillot, 1817) and Hume's leaf warbler (Phylloscopus humei, Brooks, 1878). Further, the prey abundance of leaf warblers (lepidopteran caterpillar and other arthropods) were determined in the early winter session (first week of November and December). The study recorded maximum bird abundance and species richness in the wetland associated habitats with higher prey abundance followed by barren land and agriculture field. The work documented the visit of dusky and greenish warblers to Bankura for the first time in the past 40 years and recorded the wintering of common chiffchaff and Hume's leaf warblers as the first evidence from the district.","PeriodicalId":17638,"journal":{"name":"Journal of Tropical Life Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48402279","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Coffee landscape plays an essential role in supporting the sustainable ecosystem in Banyuwangi Geopark. A number of studies have already examined ways to develop and preserve the coffee landscape and its biodiversity, especially in coffee cultivated under agroforestry system. This paper aims to describe the ecology of coffee landscapes in Banyuwangi, identify the problems and opportunities for preservation and biodiversity conservation, explore the possibilities of integrating coffee and tourism, and provide recommendations to preserve the coffee landscape and its biodiversity. Field survey, literature studies and interviews with farmers, tourism consultants, local travel planner, and local guides were conducted to get comprehensive data and information of the tourism potential of coffee landscape ecosystems. All these data were analyzed using descriptive analysis. Results of the study showed that Banyuwangi was home to numerous state-, private-, and peasant-owned coffee orchards. Coffee agroforestry had already been established for a long time, contributing to biodiversity conservations. Coffee cultivation was a common practice among communities, which later inspired the creation of a coffee festival. The high number of tourism attractions located in the geopark area coupled with the trend in tourism development, there was potential in integrating coffee into tourism. Important actions have to be done first, and these were: mapping and describing coffee orchard distribution, enhancing peasant capacity in coffee cultivation, introducing and strengthening sustainable tourism principles, and establishing regulation to ensure the preservation and conservation of coffee cultural landscapes. The outcome of analyses can be used to provide guidelines for the management of coffee landscape in the Banyuwangi Geopark area in future.","PeriodicalId":17638,"journal":{"name":"Journal of Tropical Life Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48086759","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there is limited information available on how hydroponic planting will affect the plant’s bioactivities, as well as the associated biochemical, mineral, phytochemical and antioxidant enzyme contents. In this study, we used Plectranthus amboinicus (Indian borage) as a medicinal plant model, to investigate the differences between hydroponic-planted (HP) versus soil-planted (SP) plants. Here, aqueous extracts of Indian borage from HP and SP samples were prepared, followed by testing for their phytochemical, mineral, chlorophyll and carotenoid contents. Based on our results, SP sample was detected with higher antioxidant potentials, using two different radical scavenging assays. This observation is correlating to the higher phytochemical contents (total phenolic, flavonoid, and hydroxycinnamic acids contents), as well as higher chlorophyll and carotenoid contents, detected in the SP sample. However, no significant difference was detected between HP and SP samples, in terms of their protein protection potentials. On the other hand, HP sample was tested with higher mineral contents (iron, copper, magnesium and calcium) using the atomic absorption spectroscopy method. Additionally, higher antioxidative enzymes (superoxide dismutase, catalase) were also detected in the HP sample using in vitro biochemical assays. In the future study, more plant models can be included in the comparison between HP and SP effects, to determine if a similar phenomenon is observed. Through similar studies, more related information could be gathered to guide the choice of suitable planting systems with regard to food security, in terms of both harvest yields and nutritional contents.","PeriodicalId":17638,"journal":{"name":"Journal of Tropical Life Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64519778","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Another problem is determining the viability of the consortium microbes in a biofertilizer formulation. This study aims to determine the bacterial viability of various liquid media originating from organic waste as a liquid biofertilizer carrier. Three indigenous bacterial strains under consortium for phosphate soluble (Pantoea ananatis strain 53 (BC32)), non-symbiostic Nitrogen fixation (Bacillus licheniformis strain S45) and stabilizing soil aggregate (Pseudomonas plecoglossida strain PR19) were added to liquid biofertilizer. The study evaluated 10 treatments using a randomized design with three replicates. The treatments are as follows: Peptone, molasses, Compost wash from seaweed waste, Vermiwash, molasses + glycerol, compost wash from seaweed waste + glycerol, vermiwash + glycerol, molasses + PEG (PolyEthylene Glycols)1%, compost wash seaweed waste + PEG 1%, and Vermiwash + PEG 1%. This biofertilizer formulation (liquid) was kept for 16 weeks at optimum pH 5.5. VP3 (Vermiwash made from vermicompost + PEG 1%) treatment showed the best viability of bacterial strains during the 16-week storage period. The pathogenicity test using green bean seeds Vima-1 showed that all liquid formulations of biological fertilizers with the three consortium bacterial isolates did not show signs of diseases and demonstrated better growth than the control treatment. Compared to other treatments, the best growth of bacterial strains was detected with MP2 (Molasses + glycerol) treatment. Formulations using vermiwash and PEG appear to maintain bacterial viability in the formulation effectively. However, the formulation of molasses and glycerol exerts a stimulating effect on sprouts growth.","PeriodicalId":17638,"journal":{"name":"Journal of Tropical Life Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44669480","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
