牡丹野生种与主要药用品种的药效成分含量比较

目的测定我国牡丹野生种及主要药用栽培品种的丹皮酚、芍药苷含量,为丹皮产业化提供科学依据.方法运用HPLC法检测芍药苷、丹皮酚含量,多重比较不同资源药效成分含量差异.结果(1)野生牡丹的丹皮酚、芍药苷含量范围分别为0.10%～0.61%,2.22%～5.57%;(2)栽培品种的丹皮酚、芍药苷含量范围分别为0.33%～1.43%,1.60%～2.85%.(3)北京昌平相同地块不同品种的丹皮酚、芍药苷含量范围分别为0.27%～0.75%,1.87%～3.96%;(4)不同地块同一品种的丹皮酚含量范围为0.34%～1.10%,芍药苷含量差异不大.结论野生种药效成分含量并不高于栽培品种,目前栽培的药用品种间差异显著,'建始粉'的丹皮酚含量较高,丹皮生产时应注意品种和适宜栽培地区的选择.

Comparison of the Content of Effective Components between Tree Peony Wild Species and Main Cultivars

OBJECTIVE: To determine the content of paeonol and paeoniflorin in wild tree peony species and main medicinal cultivars in order to provide scientific foundations for the industrialization of tree peony cortex. METHODS: HPLC was used to compare the effective content of different resources. RESULTS: (1) The content range of paeonol and paeoniflorin of 7 wild species was 0.10%-0.61% and 2.22%-5.57%, respectively; (2) The content range of paeonol and paeoniflorin of all cultivars from different producing area was 0.33%-1.43% and 1.60%-2.85%; (3) The content range of paeonol and paeoniflorin of different cultivars in the same place (Changping, Beijing) was 0.27%-0.75% and 1.87%-3.96%; (4) The content range of paeonol of cultivars from the same area was 0.34%-1.10%. There was no significant difference of relative content of paeoniflorin from the same areas. CONCLUSION: The relative content of main medicinal components of wild species was not higher than cultivar; the differences were significant among cultivars; the relative content of paeonol of 'JSF' was high; more attention of choosing cultivars and producing areas should be paid in tree peony cortex producing.
