Chemistry of Ayurvedic crude drugs -- V. Guggulu (resin from Commiphora mukul)--5. Some new steroidal components and stereochemistry of guggulsterol-I at C-20 and C-22

, : Chemistry of Ayurvedic crude drugs -- V. Guggulu (resin from Commiphora mukul)--5. Some new steroidal components and stereochemistry of guggulsterol-I at C-20 and C-22. Tetrahedron 38(19): 2949-2954

Chromatographic analyses of the ketonic fraction of guggulu showed the presence of at least 23 components. Further separation yielded 4 steroids, one of which has not been reported from natural sources and has been named Z-guggulsterol.
