Four new resin glycosides having macrolactone structures (jalapins), murasakimasarins I-IV, were isolated from the tubers of Ipomoea batatas (L.) Lam. ('Murasakimasari', Convolvulaceae), along with three known glycosides. Their structures were determined on the basis of spectroscopic data as well as chemical evidence. Murasakimasarin III is the first representative of a resin glycoside with 10-methylundecanoic acid as the component organic acid.
从旋花科番薯属植物Ipomoea batatas (L.) Lam.（“Murasakimasari”）的块根中分离得到了四个具有大环内酯结构的新树脂糖苷（jalapins），即jalapins I-IV，以及三个已知的糖苷。它们的结构是根据光谱数据以及化学证据确定的。Murasakimasarin III 是第一个以 10-甲基十一烷酸为组成有机酸的树脂糖苷代表。
