Correlation between environmental factors and active constituents of Polygonatum cyrtonema
摘要
Abstract
Polygonatum cyrtonema, a widely used traditional Chinese herbal medicine that mainly comes from the wild, could also be used as a food specific environmental factors influence the formation and the accumula-tion of active constituents, therefore an appropriate environment is a prerequisite for production of high-quality genuine this medicinal materials. This study aimed to explore the impact of environment factors on polysaccha-ride and saponin accumulation to enhance the quality of P. cyrtonema. Rhizomes of P. cyrtonema were collected from 17 different provenances of Zhejiang, Anhui and Hubei Provinces, China. Total polysaccharides were de-termined by the anthrone-sulfuric acid colorimetric method and total saponins by the vanillin-glacial acetic acid-perchloric acid colorimetric method. In addition, a correlation analysis between the main active con-stituents and environmental factors was also conducted. Results showed that the content range of total polysac-charides was 97.0-363.2 mg·g-1, and total saponins was 24.0-62.6 mg·g-1. Among the provenances tested, total content of these two effective constituents differed. Of all 17 samples, those from Pan ’an in Jinhua, Zhejiang exhibited the highest polysaccharide content, and the sample from Liandu in Lishui, Zhejiang had the maximum saponin content. Moreover, active accumulated temperature significantly affected polysaccharide accumulation (r=0.618, P=0.008). The results indicated an appropriate low temperature could improve the polysaccharide content in cultivated P. cyrtonema.关键词
