The Quality Standards Study of Hedyotis Diffusa

Abstract:

The research provided the reliable quality control methods for Hedyotis diffusa Willd, including identification (thin-layer identification), inspection (moisture, ash and extraction) and content determination. In thin-layer identification, samples showed same color spot as standard Hedyotis diffusa in same location; The moisture, ash, acid-insoluble ash and extraction of herb were respectively 5.9%~8.2%, 7.4%~13.4%, 1.2%~6.4% and 5.6%~11.7%. So we suggested that the moisture should lower than 13.0%, the ash should lower than 15.0% and the acid-insoluble ash should lower than 9.0% and the extraction should more than 5.0%. The content determination of p-coumaric acid ranges from 0.08 to 0.17 (%, g/g) and the suggested p-coumaric acid on the dried should not less than 0.06%. The suggestion could provide the reference to establish the quality standard of Hedyotis diffusa Willd.
