股骨头坏死(Osteonecrosis of femoral head, ONFH),是由多种因素引起供应股骨头的血供减少或丧失,导致股骨头内骨髓缺血,细胞坏死。通络生骨胶囊是由海正药业产业化开发的治疗股骨头坏死的国家新药,其主要原料为木豆叶,传统的提取方法主要是水煎或热回流水提。本研究以牡荆苷和总黄酮为指标,优化了微波辅助水提木豆叶工艺并与传统的工艺相比较,为进一步提高通络生骨胶囊疗效和充分利用木豆资源提供理论依据。研究结果如下:
确定了牡荆苷的高效液相的分析方法和总黄酮的测定方法:
色谱柱:Diamonsil C18V (5μm,250 mm×4.6 mm I.D.),流动相的比例为35:64.9:0.1=甲醇:水:甲酸(v/v/v),流速:1.0 mL/min,进样量:10 gL,柱温:35℃,检测波长:338.7 nm。
通过考察牡荆苷和芦丁两种对照品的三种测定方法可知采用硝酸铝比色法,以芦丁作为对照品,其标准曲线为:Y=15.877 X—0.009,R2=0.999,测定木豆叶总黄酮含量为9.14 mg/g DW。
优化了微波水提木豆叶的提取工艺并通过试验验证...
【英文摘要】
Osteonecrosis of femoral head (ONFH) was a pertinacious illness, because whole mechanism has not obtained and there is no a better therapy on it. TongLuoShengGu Capsule was a new national drug and industrialized developed for treating ONFH, it could activate the blood and eliminate the stagnant, tonify the kidney and strengthen the bone, relieve the swelling and remove the pain. The capsule have been used to cure the ONFH for ten years and got confirmed effect.
Pigeon pea leaves was the main raw materi...
