埃郎氏枪弹木(Mimusops elengi)系山栀科常绿乔木,广泛分布在印度,用作收敛剂、滋补剂和止泻剂。作者曾从埃郎氏枪弹木种子中分离和鉴定了几个新的三萜皂甙。本次报道了脱脂种子中一个少量的新三萜皂甙elengin的分离和结构鉴定。 实验方法及材料:埃郎氏枪弹木种子(2kg)粉碎,正丁醇萃取部分以Diaion HP(150g)柱层析,经水与30％、40％、60％、80％、100％甲醇洗脱得17个组分。再依次进行硅胶柱层析(氯仿-甲醇-水/6:4:1)、ODS中压LC(Lichroprep Rp-18.甲醇-水/7:3)和HPLC(甲醇-水/7:3),纯化得到皂
The Munusops elengi is an evergreen tree of the family Ranunculaceae, widely distributed in India and used as an astringent, tonic and antidiarrheal agent. The authors isolated and identified several new triterpene saponins from the Elagun bullet wood seeds. This report reports the isolation and structure identification of a small amount of a new triterpenoid saponin elengin from defatted seeds. Experimental methods and materials: Elagun bullet wood seeds (2kg) were crushed, the n-butanol extraction part was chromatographed on Diaion HP (150g), washed with water and 30%, 40%, 60%, 80%, 100% methanol. Take off 17 components. Silica gel column chromatography (chloroform-methanol-water/6:4:1), ODS medium-pressure LC (Lichroprep Rp-18. methanol-water/7:3) and HPLC (methanol-water/7:3) were performed one after another. , purified soap
