从益母草（LeonurusL.）的干果中分得四个新的天然甾体苷（leonurosides A-D，1-4）。通过光谱和化学方法确定了它们的结构。单糖单元被鉴定为2-乙酰氨基-2-脱氧-β-d-葡萄糖，糖苷配基是常见的3β-豆甾醇或3β-麦角甾醇衍生物。这些化合物是维管植物中甾体N-乙酰氨基葡萄糖苷的第一个代表。
Four new naturally occurring steroidal glycosides (leonurosides A–D,1–4) were isolated from the dried fruits ofLeonurus japonicus(motherwort fruit). Their structures were established by spectroscopic and chemical methods. The monosaccharide unit was identified to be a 2-acetamido-2-deoxy-β-d-glucose and the aglycone is either a common 3β-stigmasterol or 3β-ergosterol derivative. These compounds are the first representatives of steroidN-acetylglucosaminides from vascular plants.
