Structure Determination of Heishuixiecaoline A from Valeriana fauriei and Its Content from Different Cultivated Regions by HPLC/PDA Analysis

초록

A germacrane-type sesquiterpenoid was isolated and purified from a methanol extract of the roots of Valeriana fauriei (RVF) through open column chromatography using silica gel. This compound was verified to be heishuixiecaoline A by spectroscopic analysis. This compound was isolated for the first time from RVF. Quantitative analysis of heishuixiecaoline A from RVF cultivated from three different regions (Eumseong, Jinbu, and Jinan regions) was performed by combining high-performance liquid chromatography with a photodiode array detector. The extract of RVF cultivated in the Jinbu region showed the highest content (9.23 mg/g). In addition, a significant amount of the compound was detected in all RVF samples, which could be expected since it is a characteristic compound of RVF. The sesquiterpenoid group heishuixiecaoline A was isolated from RVF, a resource for various pharmacological substances, and quantitative analysis of RVF cultivated from three different regions was performed. As a result of these experiments, basic data on RVF that can be used in the development and application of pharmaceuticals and health functional foods in the future were obtained.
