1. Constituintes bioorgânicos isolados de Annona cacans Warming (Annonaceae) e avaliações de bioatividades / Bioorganic constituents isolated of Annona cacans Warming (Annonaceae) and evaluation of bioactivities.

This work reports the phytochemical investigation of wood and leaves (hexane and ethanol) and fruits (ethyl acetate) of Annona cacans Warming (Annonaceae). The research was carried out with usual chromatographic techniques including High Performance Liquid Chromatography. This investigation led to the isolation and identification of 4-hydroxy-3-5-methoxybenz

3. Properties of the System for the Mixed Function Oxidation of Kaurene and Kaurene Derivatives in Microsomes of the Immature Seed of Marah macrocarpus: Cofactor Requirements 1

The rates of oxidation of ent-kaur-16-ene to ent-kaur-16-en-19-ol, ent-kaur-16-en-19-al, ent-kaur-16-en-19-oic acid, and ent-kaur-16-en-7α-ol-19-oic acid are maximal in microsomes prepared from the endosperm of immature Marah macrocarpus seeds in which the cotyledons are approximately one-half the overall length of the seed. The supernatant fraction remaini
