以活性成分芒果苷 (mangiferin)作为质控指标 ,用 RP- HPL C法对 7个野生或栽培的射干、1个射干的茎叶和 3个射干的代用品 ,共 11个样品进行了分析。结果表明 :射干中的芒果苷含量明显高于其代用品 :川射干 (鸢尾 Iristectrnum)和白射干 (野鸢尾 I.dichotoma)。不同产地的射干也有一定的含量差异 (P<0 .0 5 )。但野生和栽培的射干 ,以及根茎和茎叶之间的芒果苷含量则无显著性差异 (P>0 .0 5 )。本法快速简便 ,重现性好 ,测定数据可作为射干质量控制和品质评价的可靠依据。 Using the active ingredient mangiferin as a quality control indicator, 11 samples of 7 wild or cultivated shoots, 1 shoot stem, and 3 shoot dry substitutes were analyzed by RP-HPL C method. The results showed that the content of mangiferin in the shoot was significantly higher than its substitutes: dry stem (Irisectrnum) and dry stem (I.dichotoma). There was also a certain difference in the content of shoots from different areas (P<0.05). However, there was no significant difference in the content of mangiferin between wild and cultivated shoots and between rhizome, stem and leaf (P>0.05). This method is quick and easy and has good reproducibility. The measurement data can be used as a reliable basis for quality control and quality evaluation of shot blasting.
