Trans-resveratrol, a phytoalexin produced by a variety of plants, has been shown to inhibit oxidative enzymes in an animal cell system. Its effect on several oxidative and antioxidative enzymes from plants was investigated using in vitro assays. Trans-resveratrol inhibited superoxide dismutase, lipoxygenase, catalase, peroxidase, polyphenol oxidase, and 1-aminocyclopropane-1-carboxylic acid oxi...

Three new triterpenoids; namely 28,28,30-trihydroxylupeol (1); 3,21,21,26-tetrahydroxy-lanostanoic acid (2) and dehydroxybetulinic acid (3) and seven known compounds; i.e., taraxerone (4); taraxerol (5); ethyl palmitate (6); herniarin (7); stigmasterol (8); ursolic acid (9) and acetyl ursolic acid (10) were isolated from the stem of Ficus aurantiaca Griff. The structures of the compounds were e...

Bioassay guided purification of methanolic extract of the bark of the plant, Thespesia populnea yielded a naphthalene derivative, (+)-gossypol (1). The structure of compound, (+)-gossypol has been established based on its physical and spectral data (UV, IR, H & C NMR and Mass). The compound has been shown moderate elastase inhibition activity when compared with control compound, ursolic acid.

Breast cancer is one of the biggest contributors to death in world. Several treatment methods such as chemotherapy, hormonal therapy, radiation and surgery have shown side effects resistance breast cancer. Bioactive compounds are now an alternative development drugs for Pearl grass plants reported contain bioactive that inhibitory activity against cells, namely ursolic acid. Most reports descri...
