摘要
[目的]比较苍耳叶4种提取方式所得提取物对微生物的抑制活性差异。[方法]采用去离子水,5%的盐酸水,无水乙醇和乙醚等不同的提取剂提取苍耳叶成分,采用倍比稀释法进行药液的稀释,考察抑菌活性。[结果]苍耳叶的不同提取方法所得的提取液对各菌种的抑制活性差异较大,各种方式中苍耳叶的酸水提取液具有最小的抑菌浓度。[结论]宜对苍耳叶的酸水提取物作进一步研究。
[Objective] To compare the antibacterial activity of extractions from the leaves of the Xanthium sibiricum Patr with different extraction ways. [Methods] The experiment got extractions using different extracting agents that water, hydrochloric acid, ethanol and aether and got different dilutions using the serial dilution method. [Results] It indicated the Xanthium sibiricum Patrin＇s extractions with different extraction ways had different antibacterial activities. The best antibacterial activity was the acid extractions and the best impregnant was the acid. [Conclusion ] It should deeply study the extractions of leaf of Xanthium sibiriucm Patr.
