不同来源的降香药材中总黄酮含量测定

目的 :对不同来源的降香药材总黄酮含量进行研究。方法 :分光光度法。结果 :降香檀药材总黄酮含量为 2 .5 1%～ 5 .82 % ,海南黄檀、山油柑总黄酮含量仅为 0 .15 %～ 0 .2 4% ,引种的印度黄檀及印度紫檀总黄酮含量也显著低于降香檀 ,进口降香商品总黄酮含量显著高于降香檀 ,但挥发油含量较低 ,其药用价值有待进一步评价。结论 :不同来源的降香药材质量差异显著

Determination of Total Flavone Content of Lignum dalbergiae odoriferae of Various Origins

OBJECTIVE:The total flavone content (TFC) of Lignum dalbergiae odorifereae (LDO) of various origins was determined.METHODS:The spectrophotometric analysis was applied. RESULTS:The results showed that the TFC of LDO is 2.51%~5.82% , that of confuse species Acronychia pedunculata, and Dalbergia hainanensis are 0.15%~0.24% respectively, and that of Dalbergia ssiso and Pterocarpus indicus introduced from India is also markedly lower than that of LDO, so that the above varieties are not suitable as used medicine. The TFC of imported products is markedly higher but their volatile oil contents are lower than that of LDO, so that their medicinal value is remained to be further evaluated. CONCLUSION:The medicinal quality of various origins of LDO are markedly difference.
