从菟丝子Cuscuta chinensis L．中分得10个化合物，分别鉴定为新芝麻脂素（neo－sesamin，Ⅰ）、山柰酚（kaempferol，Ⅱ）、山柰酚-3-O-β-D吡喃葡萄糖苷（kaempferol－3－O－β－D－glucopyranoside，Ⅲ）、4'，4，6－三羟基橙酮（Ⅳ）、槲皮素（Ⅴ）、金丝桃苷（hyperoside，Ⅵ）、软脂酸（palmiticacid，Ⅶ）、硬脂酸（stearicacid，Ⅷ）、β－谷甾醇（β－sitosterol，Ⅸ）和胡萝卜苷（daucosterol，Ⅹ）。其中Ⅰ为新化合物，Ⅱ和Ⅳ为首次从该植物中分得。

Ten compounds,neo-sesamin(Ⅰ),kaempferol(Ⅱ),kaempferol-3-O-β-D-glucopyranoside (Ⅲ),4',4,6-trihydroxyaurone(Ⅳ),quercetin(Ⅴ),hyperoside(Ⅵ),palmitic acid(Ⅶ),stearic acid(Ⅷ)，β-sitosterol (Ⅸ)and daucosterol (Ⅹ), were isolated from the seed of Cuscuta chinensis Lam. Their structrues were established by chemical and spectral methods. Among them, Ⅰ was a new compound,while Ⅱ and Ⅳ were obtained from the plant for the first time.
