Populus nigra has been introduced and largely planted in China, and the waste wood was still abandoned. Therefore, the wood extractives of Populus nigra were studied to further utilize the bio-resources. The result shown that the optimal extraction time of ethanol/methanol extraction, petroleum ether/acetic ether extraction, and benzene/alcohol extraction were 1h, 7h and 3h, respectively. Among sequential extractions, EPB extraction was the optimum extraction mode for the LR was 17.32%. The wood extractives included hexanedioic acid, bis(2-ethylhexyl) ester, phthalic acid derivatives, squalene, 3,3,7,11- tetramethyltricyclo [5.4.0.0(4,11)]undecan-1-ol, other rare drug and biomedical activities. The wood extractives of Populus nigra was fit to extract rare dibutyl phthalate and squalene.
欧洲黑杨已被引入中国并大量种植，但其废木材仍被废弃。因此，对欧洲黑杨的木材提取物进行了研究，以进一步利用这些生物资源。结果表明，乙醇/甲醇萃取、石油醚/乙酸乙酯萃取和苯/醇萃取的最佳萃取时间分别为1小时、7小时和3小时。在连续萃取中，EPB萃取是最佳萃取方式，得率为17.32%。木材提取物包括己二酸双（2-乙基己基）酯、邻苯二甲酸衍生物、角鲨烯、3,3,7,11-四甲基三环[5.4.0.0(4,11)]十一烷-1-醇、其他稀有药物和生物医学活性成分。欧洲黑杨的木材提取物适合提取稀有邻苯二甲酸二丁酯和角鲨烯。
