T. Wang(NCBI编号MH260617.1和MH260618.1)的亲缘关系较近,YHS-3次之,而YHS-1亲缘关系较远.田间数据结果显示,与另外2个品种相比,YHS-2具有花多且密,花期短以及块茎产量高的优良生产性状.建立6种苄基异喹啉型生物碱的快速检测方法分析3个品种中生物碱的含量.结果显示,YHS-2中各生物碱的含量显著优于YHS-1和YHS-3(p<0.05).表明3个品种中YHS-2更为适合浙江地区的生存环境,可作为目前延胡索浙江栽培的优质品种推广种植和使用.展开更多

Methods The hot-board, acetic-acid- induced twisting experiments and mouse auricular swelling model by injecting xylene in the abdomen of mouse were adopted to investigate the analgesic and anti-inflammatory effects of the four formulas on Kunming mice; The experiment of contractile activity on isolated rat intestine smooth muscle on Wistar rats was applied to observing the spasmolysis effect of the four formulas; The experiments of platelet aggregation induced by ADP or collagen on Wistar rats by turbidimetry method were used to observe the anti-platelet aggregation effect of the four formulas. Results Compared with RCR in two prescriptions, PCR displayed better analgesic effect （P 〈 0.05, 0.01）, while there was no difference on anti-inflammatory effect; Inhibition of the two prescriptions on smooth muscle spasm was presented well, and the prescription YD with PCR was remarkable （P 〈 0.05, 0.01）; Compared with the blank group, the two prescriptions showed outstanding effects on anti-platelet aggregation （P〈 0.01）, but no difference between RCR and PCR in two prescriptions. Conclusion PCR can improve the analgesic effect of prescription YZT and intensify the spasmolysis effect of prescription YD, which can be explained by the Chinese medicine processing regulation. Therefore, PCR is suggested to be chosen in YZT and YD used to cure pain symptoms.展开更多
