药典三种秦艽药材的DNA条形码鉴别方法
摘要：
本发明公开了药典三种秦艽药材的DNA条形码鉴别方法。该鉴别方法包括DNA提取与对得到的DNA序列拼接两大步骤。其中DNA提取通过增加裂解加热的时间，并且用等体积的酚∶三氯甲烷(1∶1)去除酚及多糖类物质的干扰，得到了较好的提取效果。然后将所得到的DNA序列进行拼接后对秦艽进行鉴定，得到了较好的鉴别效果。
摘要（英）：

The invention discloses a method for identifying DNA (Deoxyribose Nucleic Acid) barcodes of three gentiana macrophylla medicinal materials in the pharmacopeia. Three gentian macrophylla medicinal materials in the pharmacopeia are respectively Gentiana macrophylla Pall, G.crassicaulis Duthie, and G.straminea Maxim. The identification method comprises two steps of carrying out DNA extraction and splicing obtained DNA sequences, wherein in the DNA extraction step, a good extraction effect is obtained by prolonging cracking heating time and utilizing phenol and trichloromethane, between which the volume ratio is 1:1, to remove interference of phenol and polysaccharide substances; then the obtained DNA sequences are spliced to identify gentiana macrophylla so as to obtain a good identifying effect.
