丹参酮ⅡA静脉乳剂的制备与质量评价

目的：研制丹参酮Ⅱ_A静脉乳剂，并对其进行质量评价。方法：以大豆磷脂与帕洛沙姆188为混合乳化剂，油酸为助乳化剂，甘油为等渗调节剂，高速剪切法制备初乳，再采用高压匀质机对初乳进行匀化，制成丹参酮Ⅱ_A静脉乳剂。结果：自制丹参酮Ⅱ_A静脉乳剂的平均粒径为211 nm，Zeta电位为-32.1 mV，载药量为1 mg·mL^-1；25 ℃条件下避光放置1年，其粒径、Zeta电位、pH、含量及外观性状等指标均未见明显变化。结论：研制的丹参酮Ⅱ_A静脉乳剂理化性质稳定。

Preparation and quality evaluation of intravenous tanshinone ⅡA emulsion

OBJECTIVE: To prepare and evaluate an intravenous emulsion of tanshinone II(A). METHOD: Soybean phospholipid mixing with poloxamer 188 was used as emulsifier. Oleic acid and glycerol were used as co-emulsifier and isoosmotic adjusting agent, respectively. The coarse emulsion was first prepared and following homogenization was carried out for the coarse emulsion by using a high pressure homogenizer. RESULT: The average diameter of the prepared tanshinone II (A) emulsion was 211 nm with a zeta potential of -32. 1 mV. There had no changes of diameter, zeta potential, pH value, content and physical appearance for the tanshinone II (A) emulsion stored at 25 degrees C away from light during one year. CONCLUSION: The physicochemical properties of the prepared tanshinone II (A) emulsion was stable, which could meet the requirements of intravenous administration.
