摘要 鲜桑叶中的主要化学成分为水分、蛋白质、总糖、脂肪和灰分,其质量分数分别为76.32%、4.75%、16.94%、1.2%和1.05%。桑叶挥发油的回收率约为0.1%(干基)。利用GC/MS对鲜桑叶的挥发油进行了分离鉴定,共检出85个组分,确定了47个化学组分的结构。挥发油中含有大量不饱和的醇和酸,多种脂肪酸,烷烃和芳香族,甾醇类,二萜烯类,杂环类化合物。其中含量最高的是十六碳烯醇(MW296);其次是三甲基环己烯醇(Mw192)和庚烯醇(MW204)等。 The contents of water, protein, carbohydrate, lipid and ash in fresh mulberry leaves were analyzed and they were 76. 32,4. 75 ,16. 94, 1. 2 and 1. 05 ( % , w/w) , respectively. The volatile oil was extracted from fresh mulberry leaves by water, and the content was nearly 0. 1% (db,w/w). There were 85 chemical components in the volatile oil analyzed with GC/MS. Most of them are unsaturation alcohols, fatty acids, paraffinic hydrocarbons, aromatic series, sterols, diterpene olefins and heterocycle compounds. The structures of 47 chemical components in volatile oil were determined. The highest content was 3,7,11,15 - tetramethyl - 2 - hexadecen - 1 - ol ( MW 296) , and the next ones were 3 - heptene( MW204) and trimethyl - cyclohexen - 1 - ol( MW192) .
