Nematicidal activity of the derivatives of oleanolic acid

, 2021
In this study, four 3 O-acylated derivatives of oleanolic acid (1a-1d) have been prepared. Compounds 3-β-[2-Triflouromethylbenzoyloxy]-olean-12-en-28-oic acid (1c) and 3-β-[4-Triflouromethylbenzoyloxy]-olean-12-en-28-oic acid (1d) are new and 3-β-[Benzoyloxy]-olean-12-en-28-oic acid (1a) and 3-β-Dichloroacetoxy-olean-12-en-28-oic acid (1b) have ...

Steroidal and triterpenoidal glucosides from Passiflora alata

Journal of the Brazilian Chemical Society, 2001
Five glycosides were isolated from leaves of P. alata. The structures 1-5 were obtained through extensive spectral analyses as 3-O-beta-D-glucopyranosyl-stigmasterol (1), 3-O-beta-D-glucopyranosyl-oleanolic acid (2), 3-O-beta-D-glucopyranosyl-(1->3)-beta-

6b-hydroxymaslinic acid, a triterpene from Vochysia ferruginea

Journal of the Brazilian Chemical Society, 2000
A novel oleane acid was isolated from the leaves and the fruits of Vochysia ferruginea. The structure of the new triterpenoid was elucidated by NMR spectroscopy as 2alpha,3beta,6beta-trihydroxyolean-12-en-28-oic acid (6beta-hydroxymaslinic acid, 1).
