Ten dihydroxy- and trihydroxy triterpenes, viz., four taraxastanes: faradiol, heliantriol B0, heliantriol C and arnidiol; two lupanes: calenduladiol and heliantriol B2; two oleananes: maniladiol and longispinogenin; and two ursanes: brein and uvaol, isolated from the nonsaponifiable lipids of the
Rings A, D and E of faradiol (1), and ring E of both arnidiol (10) and calenduladiol (4) have been subjected to various selective chemical manipulations to modify polarity, water affinity, H-bonding, sterics, and number of aromatic groups of these anti-inflammatory natural compounds. A total of 15
A phytochemical investigation of the ethanol extract of leaves and flowers of Inula montana L. led to the isolation of one new sesquiterpene acid called Eldarin (1) and four new inositol derivatives, Myoinositol,1,5-diangelate-4,6-diacetate (2), Myoinositol,1,6-diangelate-4,5-diacetate (3),
