不同产地火麻仁品质评价

Quality Evaluation of Hemp Seed from Different Habitats

对不同产地的25份火麻仁从性状、千粒重、薄层色谱、浸出物、脂肪油含量等方面进行分析,探索火麻仁质量评价体系。结果表明,火麻仁药材均呈卵圆形或近圆形,但不同产地药材在大小、颜色、表面纹理方面有一定差异。火麻仁药材大小差异较大,平均长为0.42～0.63 cm,平均宽为0.30～0.49 cm;不同产地火麻仁千粒重有较大的差异,为13.61～49.90 g。薄层色谱鉴别结果表明,供试品色谱与对照药材色谱相应的位置上显相同颜色的斑点,颜色的深浅有一定差异;醇溶性浸出物含量在27.00%～39.89%;脂肪油含量在27.04%～37.87%。不同产地火麻仁质量有一定差异,各产地火麻仁是否都适合药用,由于目前火麻仁质量标准尚不完善,无法判定。火麻仁质量标准有待进一步完善。

In order to explore the hemp seed quality evaluation system,25 hemp seeds of different origin were tested in terms of traits,grain weight,thin layer chromatography,extraction,the content of fatty oil and other aspects.The results showed that the hemp seeds presented oval or nearly round;but there were some differences in terms of size,weight,color and surface texture of hemp seeds from different habitats.Hemp seeds average length was 0.42 ~0.63 cm,average width was 0.30~0.49 cm,and the seed weight were 13.61~49.90 g.TLC（thin layer chromatography） identification results showed that there was same color spots on the corresponding position between the samples and the control medicinal materials.Ho wever,there were some differences in the depth of color.Extract content value was 27.00%～39.89%;fatty oil content was 27.04%～ 37.87%.Different origin hemp seeds had different quality.It is still unknown if they were all suitable for medicinal purposes.Hemp seed quality standards should be further improved.
