摘要:

以浙江天台种植基地的1~5 a长梗黄精为研究对象,分析比较不同生长年限对长梗黄精品质的影响。采用单因素方差分析比较不同生长年限长梗黄精中醇浸出物、多糖、皂苷、总酚含量的差异。采用主成分分析评价不同生长年限长梗黄精的品质优劣。结果表明,不同生长年限长梗黄精中醇浸出物、多糖、总酚和总皂苷含量存在差异。2年生和4年生长梗黄精醇浸出物含量显著高于1年生、3年生和5年生,多糖含量随生长年限呈现先增长后降低的趋势,1到4年生长梗黄精多糖含量逐年增加,4到5年生长梗黄精多糖含量降低。皂苷和总酚含量随生长年限升高,在4到5年时到达平衡,4年生长梗黄精品质最优。以上说明,长梗黄精在此区域的采收时间以4年为佳。

Abstract:

This study investigated the effects of different growth years on the quality of Polygonatum filipes cultivated at the Tiantai planting base in Zhejiang Province. One-way ANOVA was used to compare differences in alcohol-soluble extracts, polysaccharides, saponins, and total phenols content among samples of varying growth years. Principal component analysis (PCA) was employed to evaluate overall quality variations. Results showed significant differences in the content of these components across growth years. Alcohol-soluble extracts in 2- and 4-year-old samples were significantly higher than those in 1-, 3-, and 5-year-old samples. Polysaccharide content initially increased with growth years (1-4 years) but declined from the 4th to 5th year. Saponins and total phenols increased with growth years and stabilized between the 4th and 5th years. It indicated that 4-year-old Polygonatum filipes exhibited the highest quality. These findings suggest that the optimal harvesting time for Polygonatum filipes in this region is four years.

Key words: Polygonatum filipes, growth years, quality differences, one-way ANOVA, principal component analysis (PCA)
