基于迷迭香酸含量的湖北夏枯草野生种质资源的评价

Evaluation of Wild Germplasm Resources of Prunella vulgaris L.Based on Rosmarinic Acid Content in Hubei

以主要有效成分迷迭香酸含量为指标评价湖北夏枯草野生种质资源。结果显示:在调查的10个区域中5个区域发现有野生夏枯草种群。而在5个产地的野生夏枯草品种中,蕲春野生夏枯草品种的迷迭香酸含量为最高(0.28%),高于国家标准(0.20%)。其他4个野生夏枯草品种,除了罗田和武汉的品种符合国家标准外,襄阳和崇阳的品种均低于国家标准,表明蕲春野生夏枯草品种品质相对较好,是优先就地保护和优先考虑种植的野生种质资源。

Rosmarinic acid content was used to evaluate the wild germplasm resources of Prunella vulgaris L. in Hubei Province. The results showed that:There were P. vulgaris populations discovered in five regions among ten investigated regions. In five wild P. vulgaris varieties,rosmarinic acid content of Qichun wild P. vulgaris variety was highest(0. 28%),higher than the national standard(0. 2%).The other four varieties of wild P. vulgaris ,in addition to rosmarinic acid content of Luotian and Wuhan varieties were in line with national standards,rosmarinic acid content of Xiangyang and Chongyang varieties were lower than national standards, indicating that quality of Qichun wild P. vulgaris variety is relatively better,it is the prior wild germplasm resources of in situ conservation and cultivation.
