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%。

Abstract: 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.

Key words: aril of Torreya grandis, chemical components, extracts, lignin
