Comparative Study on Morphological Structure and Effective Components of Scrophularia ningpoensis from Different Provenances
摘要
Abstract
This study aimed to establish a preliminary comprehensive evaluation system for Scrophularia ningpoensis,and provide references for selecting high-quality varieties and developing quality assessment criteria.Radix Scrophulariae samples from three main producing areas of Pan'an in Zhejiang,Baoxing in Sichuan and Nanchuan in Chongqing,as well as Enshi'Enxuan No.1'in Hubei were comparatively analyzed on the morphological characteristics and key component contents.External morphology was measured using vernier calipers and electronic balance.Internal texture properties were assessed with a texture analyzer.The content of index component contents was determined by high-performance liquid chromatography(HPLC).Principal component analysis(PCA)and comprehensive evaluation were performed on 23 physiological indicators.The results showed that significant variations existed in morphological structures and component contents across producing areas.The comprehensive evaluation ranked as follows:Nanchuan of Chongqing>Baoxing of Sichuan>'Enxuan No.1'>Pan'an of Zhejiang.This system reveals the multi-dimensional characteristics of the quality formation of Scrophularia ningpoensis,and provides a scientific reference for the standardized cultivation and variety improvement of Scrophularia ningpoensis.关键词
