[Objective] To determine the content of extracts from wild HERBA PLUBAGINIS ZEYLANICAE harvested at different time and HERBA PLUBAGINIS ZEYLANICAE cultivated under different conditions, so as to provide experimental basis for establishing the quality standards of HERBA PLUBAGINIS ZEYLANICAE. [Method] Samples were determined according to the methods recorded in the Appendix XA of 2010 edition Chinese Pharmacopoeia, a similarity evaluation was carried out on the contents of extracts from the stems, roots and leaves of wild and cultivated samples. [Result] Of all samples (apart from that cultivated under different light conditions), their roots, stems and leaves could be obviously distinguished, the similarity of roots and leaves was high. The total extracts contents in the roots, stems and leaves from HERBA PLUBAGINIS ZEYLANICAE harvested at different time were higher than that from wild samples; the total extracts contents were higher from January to March and from November to December, but due to the small plant size during January-March, the best harvesting period was determined to be from October to December, basically coinciding with local harvesting time; the total extracts of HERBA PLUBAGINIS ZEYLANICAE propagated with seeds and cutting seedlings were higher, but the yield of plants propagated with individual seedling was the highest. Due to the limited wild HERBA PLUBAGINIS ZEYLANICAE resources, it was suggested to use cutting seedling propagation; the HERBA PLUBAGINIS ZEYLANICAE cultivated in raw soil had the highest contents of extracts, but that cultivated in mellow soil had the highest yield, followed by that in clay. In view of the limited mellow soil resources, it was suggested to use clay; N, P and K fertilizers all could promote the plant growth. Appropriate amount of N, P and K fertilizers should be arranged; the HERBA PLUBAGINIS ZEYLANICAE cultivated under full sunlight had the highest contents of extracts; they were classified by cluster analysis into the first type, others belonged to the second type, it was suggested to adopt full light cultivation. [Conclusion] The method is simple and accurate with good reproducibility, which provides experimental data for the quality standards of HERBA PLUBAGINIS ZEYLANICAE.

2-氨基苯并噁唑化合物及BDOPV共轭聚合物的合成

氧化偶联反应由于其独特的原子经济性被人们广泛应用于有机合成领域。在传统的工作中,人们主要采用过渡金属催化活化C-H来构建各种化学键,如C-C键、C-N键、C-S键及C-O键等。然而,由于过渡金属价格的昂贵和高毒性等缺点限制了该方法在实际生产中的广泛应用。因此,无金属催化氧化偶联反应成为近年来的研究热点,我们成功地开展了经典的杂环离子液体催化苯并噁唑与胺或酰胺化合物的氧化偶联反应,并合成了一系列在药
