不同采收时间对红花质量的影响

Effects on the Quality of Carthamus tinctorius in Different Harvest Time

目的探索不同采收时间对红花质量的影响,确定红花最佳采收期,为稳定红花药材质量提供科学依据。方法在红花不同花期内一天不同时间点采集样品,通过2010版《中国药典》所规定的方法对其浸出物、羟基红花黄色素A及山柰素含量进行测定研究。结果表明在同一天不同时间点采收的红花,其指标性成分羟基红花黄色素A含量变化显著,在上午11时之前和下午5时之后采收的红花质量较好,在整个采收期采收的红花,随时间推后,质量越佳。结论从研究结果结合生产实践来分析,一天内红花最佳采收时间为11时之前和17时之后;同时分析得出在红花整个采收期内越到采收后期,采收的红花质量越佳。此采收时间段对红花GAP基地规范化采收具有一定指导意义。

Objective To provide scientific evidence for stabilizing medicinal quality of Carthamus tinctorius, effects on the quality of Carthamus tinctorius in different harvest times were studied and the best harvest time of Carthamus tinctorius was ensured. Methods The contents of extractum, HSYA and kaempferide of samples, collected in different time points on the same day in different florescence, were detected depended on the method in Pharmacopoeia of China（2010）. Results The results showed that Carthamus tinctorius collected in different time points on the same day has the most influence on HSYA composition, and Carthamus tinctoriuscollected before 11 am and after 17 pm has a better quality. The quality of Carthamus tinctorius is much better over time. Conclusion The optimal harvest time of Carthamus tinctorius is before 11 am and after 17 pm in the day, according to the analysis of the results and producing practice; The quality of Carthamus tinctorius is better over time, and the harvest time has a definite guiding significance in normalized collection of GAP base of Carthamus tinctorius.
