西非七国刺猬紫檀木材浸出液分析

Analysis for the Extractum of Pterocarpus erinaceus from Seven Different Countries in Western Africa

摘要: 本文以刺猬紫檀标本为样品，选取最优的木材化学成分抽提溶剂，然后以从非洲西部七个国家进口、且海关进口货物报关单均称为刺猬紫檀木材为样品，经过抽提超声处理后，采用GC-MS技术分别分析七种木材心材提取物的总粒子流图。结论表明：提取剂采用乙醇毒性最低，其得到的抽提物最多；来自马里和贝宁的刺猬紫檀其浸出液化学比例成分与其他5国的刺猬紫檀相关性较差，而来自几内亚比绍、加纳、塞拉利昂和尼日利亚的刺猬紫檀其浸出液化学成分比例非常接近，非洲七国刺猬紫檀的浸出液中含量最多的化合物为同一种化合物，可能是一种醇类物质，分子量为312，分子式为：C₂₀H₂₈N₂O。

Abstract: In order to choose the best solvent, Pterocarpus erinaceus was selected as the sample in this paper. Then, seven kinds of Pterocarpus erinaceus were treated as specimen. They were from seven different countries in western Africa, which were called Pterocarpus erinaceus on the customs import cargo declaration form. GC-MS extraction experiments were carried out by ultrasonic treatment and evaluating the total ion chromatograms. The results showed that ethanol was more suitable for low toxicity and getting more extractum. The correlation of the chemical composition ratio of specimen from Mali and Benin was poor with the other five countries. But it was closely related to the extractum of specimen from Guinea-Bissau, Ghana, Sierra Leone and Nigeria. The most abundant compound in the extractum of the seven kinds of Pterocarpus erinaceus was the same compound, which could be a kind of alcohol. The molecular weight was 312, and the molecular formula was C₂₀H₂₈N₂O.
