New sterol esters from the flowers of Punica granatum Linn.
Two new beta-sitosterol esters have been isolated from the flowers of Punica granatum Linn. (Punicaceae) along with the known compounds n-tricosane (3), n-heptacosanyl n-hexanoate (4), olean-5,12-dien-3beta-ol-28-oic acid (5), and olean-12-en-3beta-ol-28-oic acid (6). The structures of the new phytosterols have been elucidated as stigmast-5-en-3beta-ol-3beta-dodecanoate (beta-sitosterol laurate, 1) and stigmast-5-en-3beta-ol-3beta-tetradecanoate (beta-sitosterol myristate, 2) on the basis of spectral data and chemical analyses.
