【摘要】:目的建立木豆Cajanus cajan(L.)Millsp.叶HPLC指纹图谱,并测定荭草苷和木犀草素的含有量。方法木豆叶65%甲醇提取液的分析采用Agilent Zorbax SB-C18色谱柱(4.6 mm×250 mm,5μm);以甲醇-1%醋酸为流动相,梯度洗脱;体积流量1.0 m L/min;柱温25℃;检测波长260 nm。结果 10批样品(S1~S10)HPLC指纹图谱中有21个共有峰,除S3(0.516)外,其相似度均大于0.950。荭草苷和木犀草素分别在0.089 5~3.960μg和0.015 5~0.408μg范围内呈良好的线性关系,平均加样回收率分别为99.43%(RSD=1.32%)和98.50%(RSD=0.82%),3个产地(广东、云南、海南)样品中2种成分含有量有明显差异。结论该方法简单准确,重复性好,可用于木豆叶的质量控制。
