From the benzene extract of the root bark of Zizyphus nummularia three new peptide alkaloids have been isolated: nummularine-D 1, -E 3 and -F 5. All three contain the 14-membered ring system. Nummularine-D is N-desmethyl-integerrenine. Nummularine-E has N,N-dimethylthreonine and nummularine-F has N,N-dimethylglycine as terminal amino-acid, neither of which has been found in such alkaloids before.
从楠瓜根皮的苯提取物中分离出了三种新的肽生物碱:nummularine-D 1,-E 3和-F 5。这三个都包含14元环系统。Nummularine-D是N-去甲基-整数肾上腺素。Nummularine-E具有N,N-二甲基苏氨酸,而nummularine-F具有N,N-二甲基甘氨酸作为末端氨基酸,这在以前的生物碱中均未发现。
