山茱萸道地产区有效成分变异与性状相关研究

目的：通过对道地产区山茱萸果实有效成分变异、有效成分间及有效成分与外形、营养指标之间的相关研究，为山茱萸基于有效成分的良种选择提供理论基础。方法：采集山茱萸道地产区浙江省淳安县、临安市实生单株完熟果实，运用HPLC测定单株果实的马钱素、熊果酸、齐墩果酸含量，同时测定山茱萸果实的纵径/横径、可溶性固形物、出皮率等性状。结果：①道地产区内熊果酸、齐墩果酸、马钱素变异幅度分别为0.101 0%～0.478 6%，0.014 9%～0.127 4%，0.59%～2.30%，RSD分别为34.33%，40.48%，28.50%；②有效成分间及有效成分与外形、营养指标之间的相关关系如下：熊果酸、齐墩果酸相关极显著，相关系数为0.979 6；熊果酸、齐墩果酸与可溶性固形物成极显著负相关，相关系数分别为-0.554 4，-0.511 8；马钱素与可溶性固形物成显著相关，相关系数为0.241 2；熊果酸、齐墩果酸、马钱素与出皮率成显著负相关，相关系数分别-0.250 7，-0.244 3，-0.240 6；3种有效成分与纵径/横径相关不明显。结论：山茱萸单株间有效成分变异明显，选种潜力巨大；利用有效成分间及有效成分与外形、营养指标之间的相关关系，进行以有效成分为指标的选育种时，应以单株选种为主，可将熊果酸与齐墩果酸合并作为1个指标，并可用可溶性固形物做粗步筛选。

Study on correlation between effective ingredients of Dogwood Fruit from genuine producing regions and traits

Objective: In order to provide a theoretical foundation for the medically effective ingredient-based selection of elite cultivars in Cornus officinalis,a study has been conducted on the variation in medicinal effective ingredients of the fruit from the genuine producing areas,the correlation among effective medicinal ingredients and the correlation between effective ingredients and fruit shape as well as nutritional indexes.Method: The completely mature fruit was collected from the genuine producing areas C...
