Two new trachylobane- and one isopimarane-type diterpenoids: ent-18-hydroxy-trachyloban-3-one; ent-trachyloban-3-one; isopimara-7,15-dien-3beta-ol, were isolated from the leaves of Croton zambesicus, together with trans-phytol, beta-sitosterol, alpha-amyrin and stigmasterol. The structures were determined by extensive NMR techniques and X-ray analysis. The cytotoxicity of these compounds has be...

The time course of the different esters of chlorophyllide (Chlide) during the formation of chlorophyll a (Chl) in embryonic bean leaves containing proplastids was investigated by HPLC. After the reduction of photoactive Pchlide (Pchlide) to Chlide, three intermediates, i.e. Chlide geranylgeraniol, Chlide dihydrogeranylgeraniol and Chlide tetrahydrogeranylgeraniol were detected before the format...

Pneumonia is a disease that frequently infects toddlers. cases in 2021 caused 9.4% of deaths children aged 12-59 months. The effectiveness pneumonia treatment decreasing due to the increase Streptococcus pneumoniae ’s resistance antibiotics. application natural plant extracts such as binahong ( Anredera cordifolia ) leaf extract chosen an alternative pneumonia. purpose this study was disclose a...

Polar microorganisms produce physiologically active substances to adapt harsh environments, and these can be used as biomedical compounds. The green microalga Micractinium variabile KSF0031, which was isolated from Antarctica, produced phytol, a natural antimicrobial agent. Furthermore, several polyunsaturated fatty acids (PUFAs), including omega-3, exhibit antioxidant properties. Here statisti...
