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.
从石榴（石榴科）花中分离出两种新的β-谷甾醇酯，同时还分离出了已知化合物正二十三烷（3）、正庚基正己酸酯（4）、齐墩果-5,12-二烯-3β-醇-28-酸（5）和齐墩果-12-烯-3β-醇-28-酸（6）。基于光谱数据和化学分析，新植物甾醇的结构已被确认为豆甾-5-烯-3β-醇-3β-十二烷酸酯（β-谷甾醇月桂酸酯，1）和豆甾-5-烯-3β-醇-3β-十四烷酸酯（β-谷甾醇肉豆蔻酸酯，2）。
