Pharmacognostic specifications and lawsone content of Lawsonia inermis leaves

Abstract

BACKGROUND: L. has been used as a traditional or folk medicine for the treatment of a wide range of skin infectious diseases. OBJECTIVE: leaves. MATERIALS AND METHODS: leaves from 12 sources were evaluated according to the WHO guideline of quality control method for medicinal plant materials. The lawsone contents were analyzed by thin-layer chromatography (TLC) coupled with densitometry and image analysis. RESULTS: . CONCLUSION: leaves, and the development of TLC method could be applied to determine lawsone content in this plant material. SUMMARY: : LOD: Limit of detection; LOQ: Limit of quantitation; RSD: Relative standard deviation; TLC: Thin layer chromatography; UV: Ultraviolet; Rf value: Relative to front value.
