补骨脂为常用补肾壮阳中药。国内外对其化学成分已有报道,但生药学方面未见系统研究。本文报道补骨脂生药性状、组织构造的鉴别特征,并用薄层层析法、紫外分光光度法、薄层-光密度法进行了补骨脂的质量分析,指出不同产地生药质量有较大差异。实验并证明用薄层-光密度法测定补骨脂所含的补骨脂素与异补骨脂素方法简便、准确、可行。 Psoraleachy is a commonly used traditional Chinese medicine for kidney yang. Domestic and foreign chemical compositions have been reported, but no systematic research has been conducted on pharmacognosy. In this paper, the characteristics of the character and tissue structure of psoralen were reported, and the quality of psoralen was analyzed by thin layer chromatography, ultraviolet spectrophotometry, and thin-layer densitometry. It was pointed out that there was a great difference in the quality of crude drug from different areas. . Experiments have shown that it is simple, accurate, and feasible to determine the psoralen and isopsoralen contained in psoralen by thin-layer densitometry.
