摘 要 目的:建立蒙药地梢瓜的质量标准。方法:采用薄层色谱法(TLC)鉴别地梢瓜药材;按2015年版《中国药典》(四部)方法
检测药材中的水分、总灰分、醇溶性浸出物含量;采用高效液相色谱法(HPLC)测定药材中地梢瓜苷的含量。结果:TLC图斑点清
晰,供试品(地梢瓜药材)与对照品(地梢瓜苷)在相应位置上均显示相同的黄绿色荧光斑点。22 批地梢瓜药材的水分含量为
6.18%~12.97%,总灰分含量为 4.64%~7.95%,醇溶性浸出物含量为 12.46%~32.70%。地梢瓜苷检测进样量的线性范围为
0.048~3.050 μg(R =0.999 9);精密度、稳定性、重复性、耐用性试验的 RSD 均小于 1%;加样回收率为 104.03%~106.36%
2
(RSD=0.96%,n=6);22 批地梢瓜药材中地梢瓜苷的含量为 0.006 2%~0.130 5%。结论:初步拟定地梢瓜中水分不得超过
11.50%,总灰分不得超过7.50%,醇溶性浸出物不得少于17.00%,地梢瓜苷含量不得少于0.05%。所建质量标准可用于蒙药地梢
瓜药材的质量控制。

ABSTRACT OBJECTIVE:To establish the quality standards of Mongolian medicine Cynanchum thesioides. METHODS:TLC
was used for the qualitative identification of C. thesioides. According to 2015 edition of Chinese Pharmacopeia(part Ⅳ),the
moisture,total ash and ethanol-soluble extract were determined. HPLC method was used to determine the content of thesioideoside
in C. thesioides. RESULTS:TLC spots were clear,there were same yellow green fluorescent spots on the corresponding position of
the sample(C. thesioides)and control(thesioideoside). In 22 batches of samples,contents of moisture were 6.18%-12.97%,total
2
ash were 4.64%-7.95%,ethanol-soluble extract were 12.46%-32.70%. The linear range of thesioideoside were 0.048-3.050 μg(R =
0.999 9). RSDs of precision, stability, repeatability and durability tests were all less than 1% . The recoveries were
104.03%-106.36%(RSD=0.96%,n=6). The contents of thesioideoside in 22 batches of C. thesioides were 0.006 2%-0.130 5%.
CONCLUSIONS:It is suggested that the moisture and total ash should not exceed 11.50% and 7.50%,respectively;the contents
of ethanol-soluble extract and the sioideoside are no less than 17.00% and 0.05%,respectively. The established quality standards
can be used for quality control of Mongolian medicine C. thesioides.
