Qualitative analysis for phytochemicals were done after each treatment. M. acuminate (Banana) extracts showed moderate effect against the growth of tested microorganisms while this effect became much better after treated with fungal species (Fusarium moniliform; Rhizopus stolonifer; Aspergillus parasiticus; Alternaria alternate; Penicillium expansum and Aspergillus flavus). The MIC ranging from 6.25 to 100 mg/ml, MBC and MFC ranging from 3.125 to 250 mg/ml. Citric acid was the most produced organic acid obtained from banana wastes and highly increased after treatment with fungal isolates used. The antioxidant potential of M. acuminata leaves and pseudostem wastes enhanced after treatment with fungal extracts relative to butylated hydroxytoluene (BHT). Phytochemical screening confirmed the presence of active compounds like glycosides, tannins, saponnins, phenols, steroids and flavonoids in the M. acuminate extracts.

Samples were collected from December 2021 to May 2022. In total, 263 blood samples were collected from the patients who visited Bahawalpur Victoria Hospital, Bahawalpur Pakistan. A rapid diagnostic test (ICT) was used to diagnose Hepatitis B surface antigen and anti-HCV, followed by an enzyme-linked immunosorbent assay (ELISA). The data were analyzed using IBM SPSS version 22. In total, 263 samples were tested; 5.3% (14/263) tested positive for HBV, 25.4% (67/263) tested positive for HCV, and 0.76% (2/263) were co-infected.

Psidium oligospermum Mart. Ex DC (Myrtaceae) is among species of this genus whose extracts have not been investigated in phytochemical or biological studies, making it a potential source of bioactive compounds. This objective of this study was to investigate properties bioactive of stem and leaf extracts of P. oligospermum using different solvents (hexane, ethyl acetate, and ethanol). Antimicrobial potential, antioxidant activity, and effects on cell viability were evaluated, as well as concentrations of total phenolics and flavonoids and other chemical parameters. The extracts inhibited Gram-positive bacteria (Staphylococcus aureus and Micrococcus luteus), Gram-negative bacteria (Pseudomonas aeruginosa and Salmonella choleraesuis), and fungi (Candida albicans and Candida glabrata) by the disk diffusion and minimum inhibitory concentration methods, with bactericidal activity for Gram-positive bacteria. The extracts showed antioxidant effects, with reductions of up to 84% in DPPH free radicals. The absence of toxicity in extracts obtained with ethanol and ethyl acetate was observed through hemolytic tests with sheep erythrocytes and viability tests using Artemia salina, whereas the hexane leaf extract showed moderate toxicity. The bioactivity of the extracts is related to the presence of different classes of phytochemicals such as alkaloids, triterpenoids, steroids, saponins, anthraquinones, phenols, and flavonoids. These findings provide important chemical and pharmacological information indicating that Psidium oligospermum is a promising source of compounds with therapeutic properties; however, further research using other evaluation techniques is needed.</p>","PeriodicalId":55326,"journal":{"name":"Brazilian Journal of Biology","volume":"85 ","pages":"e290748"},"PeriodicalIF":0.0,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143659873","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}

Similarly, biological control with parasitoids can be an effective tool when integrated with bioinsecticides. However, the safety of natural insect enemies must be prioritized within pest control programs. The objective was to evaluate the effects of the water-based extracts of Serjania erecta Radlk (Sapindaceae) and Serjania marginata Casar (Sapindaceae), at 5% and 10% concentrations, on the reproduction of Tetrastichus howardi (Olliff, 1893) (Hymenoptera: Eulophidae) in larvae of P. xylostella, topically treated with extracts. In addition, we evaluated the survival of adult females of T. howardi exposed to the respective extracts of Serjania spp. For this purpose, two bioassays were conducted. In the first, 4th instar larvae of P. xylostella were selected, and 20 μL of each treatment was applied topically (S. erecta 5%, S. erecta 10%, S. marginata 5%, S. marginata 10%, distilled water) in each larva and then exposed to T. howardi parasitism for 48 hours. The percentage of parasitism and emergence (%), life cycle length (days), total number of progeny, sex ratio and adult longevity were evaluated. In the second bioassay, the ASPECLE (Evaluation of Pesticide Selectivity under Extended Laboratory Conditions) system, adapted from the International Organization for Biological Control (IOBC) standard model, was used. In this bioassay, five cabbage leaf disks were introduced in each glass cylinder of the ASPECLE system, duly treated with distilled water, aqueous extracts of S. erecta and S. marginata, at concentrations of 5% and 10%, or acephate. Subsequently, ten adult females of T. howardi were released in each cylinder and the system was activated. Parasitoid survival was evaluated for 24, 48, 72, 96 and 120 hours. The aqueous extracts of S. marginata and S. erecta at concentrations of 5% and 10% did not interfere in the parasitism of T. howardi on 4th instar larvae of P. xylostella. Field experiments should be developed to prove the negative effect of aqueous extracts of S. marginata and S. erecta on other biological characteristics of T. howardi.
