hypoglycemic, gastric emptying inhibitory, and gastroprotective principles and the structure elucidation of calendasaponins A, B, C, and D, two newionone glucosides (officinosides A and B), and two sesquiterpene oligoglycosides (officinosides C and D), were isolated from the flowers of Egyptian Calendula officinalis. The structures of the officinosides were elucidated on the basis of chemical and physicochemical
Four new eudesmane-typesesquiterpenederivatives, 3β-[(β-D-glucopyranosyl)oxy]-11αH-eudesm-4(14)-en-12,8β-olide (1), (3β)-eudesma-4(14),11(13)-diene-3,12-diol (2), 3β-[(β-D-glucopyranosyl)oxy]eudesma-4(14),11(13)-dien-12-ol (3), and 3β-[(β-D-glucopyranosyl)oxy]eudesm-4(14)-en-11-ol (4), together with the known (3β)-eudesm-4(14)-ene-3,11-diol (5) were isolated from Saussurea conica, and their structures

Several new sesquiterpenes of eudesmane and guaiane types are isolated from the aereal parts of Chenopodiumbotrys. The structures were assigned by spectroscopic methods and confirmed by partial synthesis.
