{"title":"Antioxidant and lipid peroxidation inhibitory potentials of the unripe and ripe of Citrus mitis Blanco pulps and peels from south Thailand","authors":"Chanate Wanna, Narumon Boonman, Sirirat Phakpaknam","doi":"10.14719/pst.2693","DOIUrl":"https://doi.org/10.14719/pst.2693","url":null,"abstract":"Citrus mitis Blanco fruit contains high levels of vitamin C, phenolics, and flavonoids, which exhibit a wide range of beneficial biological effects. The current research aimed to evaluate the levels of vitamin C, flavonoid, total phenolic contents, and antioxidant properties, as well as the inhibitory effects on lipid peroxidation, in both unripe and ripe fruit tissues (pulps and peels) of C. mitis Blanco. The fruit tissues were obtained from the Hat Som Paen subdistrict in Ranong province, located in the southern region of Thailand. Fruit tissues were extracted using maceration with 80% ethanol and water solvents. Vitamin C quantification was achieved using the 2,6-dichloroindophenol titrimetric method. Total flavonoid content was determined using the aluminium chloride colorimetric method, while total phenolic content was assessed using the Folin-Ciocalteu procedure. Additionally, ABTS and DPPH assays were used to assess the antioxidant properties. The measurement of lipid peroxidation inhibitory activity was carried out using the thiobarbituric acid reactive substances (TBARS) assay. The findings indicated that the water extract exhibited higher levels of vitamin C compared to the 80% ethanolic extract. In contrast, the 80% ethanolic extract revealed greater amounts of total phenolic and flavonoid contents than the water extract. The water extract of unripe pulp exhibited the highest vitamin C content among all the extracts, reaching 36.74 mg/100 g fresh weight (FW). The 80% ethanolic extract of unripe peel demonstrated the highest level of total phenolic content (35.67 mg gallic acid equivalent (GAE)/g extract), while ripe peel exhibited the highest total flavonoid content (16.88 mg catechin equivalent (CE)/g extract). Both unripe and ripe fruit extracts exhibited antioxidant and lipid peroxidation inhibitory activities. The 80% ethanolic extract from unripe peel demonstrated the most significant antioxidant activities against DPPH (6.31 mg trolox equivalent (TE)/g extract) and ABTS (7.69 mg TE/g extract). Moreover, the 80% ethanolic extract of unripe peel showed the highest level of inhibitory activity against lipid peroxidation, with a value of 74.62%. These results underscore the potential bioactivities of unripe and ripe C. mitis Blanco fruit tissues, which can offer nutritional and health benefits. These properties make them particularly valuable in the food industry due to their excellent antioxidant and lipid peroxidation inhibitory characteristics.","PeriodicalId":20236,"journal":{"name":"Plant Science Today","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136114274","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}

Drug resistance has emerged as a global giant, causing all available treatment options to fail. The solution to this problem is in the phytochemicals of plants with antibacterial and drug resistance modulation properties. Phytochemicals might be able to get rid of efflux pumps, drug-modulating enzymes, resistance genes, quorum sensing, and biofilm, all of which cause pathogens to be resistant to drugs. Moreover, anti-obesogenic and cardioprotective properties are also observed in phytochemicals. Additionally, studies show the success of phytochemical-based nanoparticles in drug resistance regulation. This review emphasizes phytochemicals' different mechanisms of action and their derivatives in curbing drug-resistant pathogens and cancer cells.","PeriodicalId":20236,"journal":{"name":"Plant Science Today","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136114154","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, the utilization of ginger in the pharmaceutical industry is still moderate and not commensurate with the potential of the Vietnamese horticulture industry, mainly due to a lack of information about the quality of input materials. In this study, we compared the volatile compounds of gingers collected from 13 provinces of Vietnam using GC/MS and GC-FID analysis to provide a basis for selecting and standardizing input materials. Furthermore, ginger essential oil from Ben Tre province of Vietnam exhibited significant antibacterial activity particularly in inhibiting Gram-positive bacteria, including S. aureus and S. epidermidis, with inhibition zones of 30.00 ± 1.41 and 24.67 ± 3.30 mm, respectively. However, no significant inhibition was observed against Gram-negative bacteria P. aeruginosa and E. coli. We also isolated 5 non-volatile compounds from ginger extract, namely 6-shogaol (1), quercetin (2), rutin (3), beta-sitosterol (4) and beta-sitosterol-3-O-beta-D-glucopyranoside (5). Among them, compounds 1–3 displayed cytotoxicity against Hep3B, SK-LU-1, MCF-7, SK-LU-1, SW480 and HepG2 tumour cell lines, with an IC50 values ranging between 62.7 ± 2.1 and 97.6 ± 1.1 µM, using Ellipticine as a positive control. Compounds 4 and 5 showed cytotoxicity against Hep3B and HepG2 tumor cells, with the IC50 values ranging between 21.5 ± 5.1 and 46.9 ± 3.7 µM but did not exhibit any significant cytotoxicity against SW480 and SK-LU-1 cells. Compound 4 also demonstrated middling cytotoxicity against the MCF7 cell line, with an IC50 value of 43.6 ± 5.1 µM.

Different types of gynecological cancers differ by distinct attributes, risk determinants, and therapeutic methodologies. So, depending on the type and stage of the cancer, a tailored combination of therapies is required for the treatment. However, it is shocking that the side effects of these therapeutic methods range from mild to severe. Hence, developing innovative therapeutic approaches to improve patient outcomes is imperative. Here's the juncture where the role of plant-derived compounds in curing gynecological cancers becomes evident. Various plant-derived compounds, including phytochemicals, polyphenols, alkaloids, and terpenoids for their cytotoxic, apoptotic, anti-angiogenic, and immunomodulatory properties, have been examined so far. Besides, certain phytocompounds can modulate hormonal-dependent gynecological cancers. Among the widely studied phytocompounds, RSV is the one that is extensively researched in vitro, in vivo and in-silico studies. In this context, this review article provides insights into the present-day knowledge about how RSV can potentially manage gynecological cancers. However, further research is needed to standardize their mode of action, optimal dosages, and potential interactions with conventional treatments. Rigorous clinical trials must validate their safety and efficacy profiles in different patient populations. As a result, a novel avenue for treating and preventing gynecological cancers could emerge by harnessing the multifaceted properties of phyto compounds, instilling new hope for patients and healthcare providers alike.","PeriodicalId":20236,"journal":{"name":"Plant Science Today","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136184873","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}

MTT assays (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide) were used to determine the percentage of viability in adenocarcinomic human alveolar basal epithelial cells (A549) and Medical Research Council cell strain 5 (MRC5) cell lines incubated with methanolic extract and valerenic acid for 48 hr. The methanol extract was prepared by adding 1000 mg of rhizomes to 100 mL of methanol, followed by sonication for 30 minutes, stirring, and centrifugation at 4000 rpm for 10 minutes. Minimum inhibitory concentration (MIC) and agar gel diffusion were used to assess the antimicrobial activity of the methanol extract of valerian against two important pathogenic microorganisms, Staphylococcus aureus and Candida albicans. However, valerenic acid did not reveal antimicrobial activity at doses of 200, 100, 50, 25, 12.5, and 6.25 µg/mL. The methanolic extract of V. officinalis contains high quantities of sesquiterpenes, specifically valerenic acid, which did not show cytotoxic effects on A549 and MRC5 cell lines as assessed by the MTT assay. In vivo evaluation of the extract in mice and guinea pigs did not reveal any toxic effects based on histopathological and clinical symptom assessments.

Our results revealed that the mustard crop showed a substantial increase in yield supporting characters such as the number of siliqua and seeds per siliqua when sown at last week of September as compared to the second week of October, whereas the late sown crop resulted in less yield due to the heat stress faced by crop during the anthesis stage as compared to early and optimum sowing. The mean seed yield per plant showed a positive correlation with mean test weight. We established the positive effect of early sowing over optimal and late sowing in Indian mustard; further, we found a few mustard accessions were able to resist different climatic conditions.
