Novel ring A rearranged isomers with γ-lactone from the fruits of Aphanamixis grandifolia
TL;DR: Aphagranols A (1 ) and B (2 ) were isolated from the fruits of Aphanamixis grandifolia and their structures were determined by spectroscopic analyses and further confirmed by their unique acetylated derivative aphagranol C (3 ) as discussed by the authors.
Cytotoxic Compounds from Calotropis gigantea (Linn.) and Amoora rohituka (Roxb.)
TL;DR: Two compounds, named β-boswellic acid and 2methoxy-14-calamenenone were isolated from the flowers of Calotropis gigantea and stem bark of Amoora rohituka and their cytotoxic activity against A431 (human vulval-derived epidermoid carcinoma) cell line was examined.
