Research on base source and determination of total flavone content of cuscutae semen from different producing areas
The origin of cuscutae semen from different origins was investigated,and the total flavonoid content was determined.Through characteristics,microscopic and TLC identification methods,the authenticity and origin of cuscutae semen from 10 origins were investigated;the content of total flavonoids in cuscutae semen from 10 origins was determined by UV spectrophotometry.The results showed that the cuscutae semen from 10 origins were all authentic,among which the origin of Luobei in Heilongjiang,Ximeng and Alashan in Inner Mongolia was Cuscutachinensis,and the origin of Jiaozuo in Henan,Jining in Shandong,Liuan and Huoshan in Anhui,Nanning in Guangxi,Baoji in Shanxi,Wenshan in Yunnan was Cuscutaaustralis.There was no significant difference in the total flavonoid content of cuscutae semen from 10 origins,with the highest content of 18.50 mg·g-1 in Jiaozuo in Henan,and the lowest content of 16.98 mg·g-1 in Wenshan in Yunnan.This paper provided a reference for the formulation of quality standards and the development and utilization of cuscutae semen.
