摘要
目的:建立射干苷标准品的质量标准。方法:采用定性、定量分析方法,依照2005年版《中国药典》(二部)附录有关规定,对射干苷各项指标进行检测。结果:3批射干苷标准品的比旋度为—28°~—30°([α]2D5,c0.11,吡啶),百分吸收系数(E11%cm)为790~830,熔点为252~254℃,灰分<0.5%,高效液相色谱法测定射干苷含量>99.5%。结论:各项指标均符合标准物质的相关规定,所建标准可用于射干苷标准品的质量控制。
OBJECTIVE: To establish the quality standard of Belamcandin standard substance.METHODS: Different indices of standard elamcandin were examined with quantitative and quantitative analyses according to the corresponding measures stipulated in the Appendix of pharmacopoeia of people' s republic of China(part Ⅱ ) published in 2005.RESULTS: The specific rotatory power of 3 batches of standard Belamcandin was -28°--30° ( [ a ] D^25, c0.11, Pyridine) ; the E1cm^1%,was 790- 830; the melting point was 252-254 ℃ and the ash content was less than 0.5% .The content of Belamcandin in the products was above 99.5% as revealed by HPLC.CONCLUSION: All of the indices were shown to meet the standards for standard substances and the established standard can be used for the quality control of standard Belamcandin.
