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.%多花黄精Polygonatum cyrtonema的根茎是药食同源的中药材，用途广泛，目前多利用野生资源。收集了不同种源的多花黄精，采用蒽酮-浓硫酸比色法和香草醛-冰醋酸-高氯酸比色法分别测定根茎中总多糖和总皂苷质量分数，并分析这2种有效成分与环境因子间的相关性。结果表明：多花黄精总多糖质量分数为97.0~363.2 mg·g-1，总皂苷质量分数为24.0~62.6 mg·g-1，来源于17个不同种源地的多花黄精化学质量存在较大的差异：浙江金华磐安种源的多糖质量分数最高，浙江丽水莲都区皂苷质量分数最高；环境因子中活动积温与多糖质量分数呈极显著负相关（r＝0.618， P＝0.008），生长期适当的低温有利于多糖的积累。表3参11
