Analysis and Comparison of the Main Efficacy Components of Roots of Xiaoxianggou from Different Sources

In order to screen and obtain excellent Xiaoxianggou （Radix et Chulis Fici Angustifoliae） germplasm resources, the contents of psoralen, total flavonoids, total phenols and total triterpenoids in 2-year-old xiaoxianggou from 14 different sources were determined. The results showed that the highest content of psoralen in sample No. 14 （Suichang County, Zhejiang Province） was 8.14±0.24 g·kg⁻¹; the highest content of flavonoids in sample No. 9 （Lishui City, Zhejiang Province） was 14.70±0.29 g·kg⁻¹; the total phenol content in sample No. 3 （Longquan City, Zhejiang Province） was significantly higher than that in other samples, with 23.06 ±0.96 g·kg⁻¹; the total triterpene content in sample No. 7 （Sanming City, Fujian Province） was significantly higher than that in other samples, with22.07±0.88 g·kg⁻¹. In summary, samples No. 3, 7, 9 and 14 were initially selected for further optimization at a later stage, with sample No. 3 being the best.This study provides a scientific basis for the selection and breeding of germplasm resources of Xiaoxianggou.
