摘要：研究了新鲜香榧假种皮中所含的挥发油、溶剂提取物、单宁物质、非单宁物质、木质素等主要化学组分及其含量。测定了新鲜原料中的挥发性精油的提取率及密度、折光率、比旋光度等物理化学性质。结果表明,新鲜的香榧假种皮精油提取得率按绝干物计算为5.5%,提取精油后残渣用溶剂甲苯提取的收率为19.7%。精油中主要含单萜类化合物,含量74.66%;残渣甲苯提取物主要含二萜类物质,含量78.22%;新鲜香榧假种皮中含有1.8%的单宁物质、18.9%的非单宁类物质、20.1%的木质素;水蒸气蒸馏残渣和溶剂抽提残渣中含木质素分别为17.13%和17.16%。
The volatile oil, solvent extract, tannin, non-tannin, lignin as well as their contents in fresh aril of Torreya grandis were studied in this paper. The yield, density, refractive index, specific rotation and non-volatile mater content of volatile oil from fresh aril of T. grandis were determined. The results showed that a volatile oil was collected from steam distillation of the fresh aril of T. grandis in 5.5 % （ based on the dry matter）, and a toluene extractive was gained from the residue after volatile oil distillation in 19.7% （by toluene）. The volatile oil contained mainly monoterpene, and the solvent extract contained maninly diterpene. In fresh aril of T. grandis, the contents of tannin material, non-tannin material and lignin were 1.8 %, 18.9 % and 20.1%, respectively. The contents of lignin in the steam distillation residue and solvent extraction residue were 17.13 % and 17.16 %, respectively.
