To study the chemical constituents of Mori Cortex.
The compounds from the dichloromethane-methanol extracts were isolated by the silica gel column chromatography, and their structures were identified by the spectral analysis and chemical evidence.
Eight compounds were obtained and their structures were identified as 3-acetyl-beta-amyranol (1), neotocopherol (2), alpha-amyrin (3), clionasterol (4), betulinic acid (5), moracin O (6), morusin (7) and morusignin L (8).
Componds 2 and 4 are obtained from this plant for the first time.
研究桑白皮的化学成分。
采用硅胶柱色谱法从二氯甲烷 - 甲醇提取物中分离化合物，并通过光谱分析和化学证据鉴定其结构。
得到8个化合物，其结构分别鉴定为3 - 乙酰基 - β - 香树脂醇（1）、新生育三烯酚（2）、α - 香树脂醇（3）、海绵甾醇（4）、桦木酸（5）、桑辛素O（6）、桑色素（7）和桑根皮素L（8）。
化合物2和4首次从该植物中获得。
