Abstract Three new sitosterol acylglycosides have been isolated from the ethereal extract of the aquatic plant Pistiastratiotes . The structures sitosterol-3- O -[2′,4′- O -diacetyl-6′- O -sterayl]-β- d -glucopyranoside, sitosterol-3- O -[2′- O -stearyl]-β- d -xylopyranoside and sitosterol-3- O -[4′- O -stearyl]-β- d -xylopyranoside have been defined by spectroscopic data and chemical conversion.
摘要 从水生植物Pistia striotes的醚提取物中分离出三种新的谷甾醇酰基糖苷。结构式谷甾醇-3-O-[2',4'-O-diacetyl-6'-O-sterayl]-β-d-吡喃葡萄糖苷、谷甾醇-3-O-[2'-O-硬脂基]-β- d -xylopyranoside 和sitosterol-3-O -[4'-O -stearyl]-β-d -xylopyranoside 已通过光谱数据和化学转化定义。
