The leaves of Azadirachta indica L. and Melia azedarach L. were analyzed for their medicinal properties. Both extracts were rich in phenolic and flavonoid compounds. In vitro testing showed they had strong anti-SARS-CoV-2 activities with low IC50 values of 8.451 and 6.922 μg/mL, respectively. Both extracts also had significant antibacterial activities against both Gram-negative and positive bacterial strains. The extracts were safe with high CC50 values of 446.2 and 351.4 μg/ml, respectively, and high selectivity indices. Further in vivo investigation is needed to confirm their potential as a treatment for COVID-19 and antimicrobial purposes.
This study looked at the pollen of 15 species of Asteraceae on the Sikaram Mountain Pak-Afghan border using microscopic techniques. The researchers observed and measured 15 pollen characters such as size, shape, and exine sculpturing. They found that pollen grains are usually tricolporate and have varying shapes and sculpturing. The study also measured pollen fertility and sterility and used clustering analysis to separate closely related taxa. Ultimately, the researchers conclude that palynological study is crucial for taxonomy and can be improved with further analysis.
