Two new cinnamic acid esters from Marine brown alga Spatoglossum variabile

Chem Pharm Bull (Tokyo). 2002 Sep;50(9):1297-9. doi: 10.1248/cpb.50.1297.

Abstract

Two new natural products, n-butyl and isopropyl 3,5-dimethoxy-4-hydroxycinnamate were isolated from Spatoglossum variabile. Three known compounds, methyl 3,4,5-trihydroxybenzoate, 2-deoxyinosine and 9-beta-(D-ribofuranosyl)adenine were isolated for the first time from the methanolic extracts of this alga. The structure elucidations of the new compounds were carried out with the help of modern spectroscopic techniques.
