Phytochemistry | 1970

Coumarins of Artemisia dracunculoides and 3',6-dimethoxy-4',5,7-trihydroxyflavone in A. arctica.

Werner Herz; S.V. Bhat; P.S. Santhanam

Abstract Six coumarins were isolated from Artemisia dracunculoides Pursh. Two of these are new, 7,8-methylenedioxy-6-methoxycoumarin and the γ,γ-dimethylallyl ether of scopoletin. The four others were scopoletin, scoparone, daphnetin methylene ether and daphnetin 7-methyl ether. Artemisia arctica Less. ssp. saxicola (Rydb.) Hulten yielded 3′,6-dimethoxy-4′,5,7-trihydroxyflavone.


Phytochemistry | 1972

3-epi-betulinic acid, a new triterpenoid from Picramnia pentandra

Werner Herz; P.S. Santhanam; Inger Wahlberg

Abstract Extraction of the bark of Picramnia pentandra Sw. gave as the main component a new triterpenoid, whose structure was established as 3-epi-betulinic acid.
