血管紧张素转换酶抑制肽RLSFNP脂质体的制备工艺优化
Optimization of Preparation of Angiotensin Converting Enzyme (ACE) Inhibitory Peptide RLSFNP Liposomes
摘要
Abstract
The objective of the present study was to optimize the preparation of liposomes incorporating the angiotensin converting enzyme (ACE) inhibitory peptide Arg-Leu-Ser-Phe-Asn-Pro (RLSFNP) using combination of one-factor-at-a-time method and response surface methodology.The response variable was the entrapement efficiency.The optimum preparation conditions were determined as follows:soy lecithin,120.0 mg;cholesterol,24.6 mg;RLSFNP,15.3 mg;ether,15 mL;PBS buffer (pH 7.4),5.8 mL;and ultrasonication time,5.2 rain.Under these conditions,the average diameter,potential and entrapement efficiency of liposomes were 168 nm,-31.2 mV and (67.5 ± 0.8) %,respectively.The liposomes could sustainably release RLSFNP.关键词
