文题释义:
姜黄素羟丙基-β-环糊精包合物:羟丙基-β-环糊精具有“内疏水、外亲水”的特殊立体环状结构;环糊精通过非共价键形式将难溶性药物姜黄素包合进其疏水空腔,既能提高姜黄素的水溶性,也能在一定程度上改善姜黄素见光易降解的特性。
单向灌流在体肠吸收:单向灌流法以较低的灌流速度(实验研究的流速为0.2 mL/min)对大鼠某一肠段进行单向灌流,实验条件接近动物体内肠道环境[Krebs-Ringer循环液温度为(37±2) ℃];体内肠吸收实验既能保证实验动物血液和淋巴液的供应,也能提高实验动物各肠段的生物活性。
 
 
背景:姜黄素具有良好的抗癌、抗炎等药理作用,但水溶性极低,影响了其药理活性的发挥。
目的:观察姜黄素羟丙基-β-环糊精包合物及姜黄素在体肠吸收情况。
方法:采用研磨法制备姜黄素羟丙基-β-环糊精包合物;检测姜黄素羟丙基-β-环糊精包合物与姜黄素的溶解度。取12只雄性SD大鼠,建立在体肠段单向灌流模型(每只大鼠选取十二指肠、空肠、回肠及结肠4个肠段),随机分2组进行药物灌流,实验组灌流姜黄素羟丙基-β-环糊精包合物水溶液,对照组灌流姜黄素混悬液,收集各肠段的灌流药液,采用紫外可见分光光度法测定姜黄素羟丙基-β-环糊精包合物及姜黄素在大鼠体内各肠段的吸收速率常速(Ka)和有效渗透率(Papp)。

结果与结论:姜黄素羟丙基-β-环糊精包合物在水中的溶解度较姜黄素提高了33.68倍;姜黄素羟丙基-β-环糊精包合物的吸收速率常数Ka结果为:十二指肠>回肠>空肠>结肠,有效渗透率Papp结果为:结肠>十二指肠>回肠>空肠,并且姜黄素羟丙基-β-环糊精包合物在大鼠各肠段的吸收较姜黄素明显提高(P < 0.05);结果表明,姜黄素羟丙基-β-环糊精包合物能够明显改善姜黄素在大鼠肠内的吸收情况。

Abstract:

BACKGROUND: Curcumin has good anticancer and anti-inflammatory effects, but which is limited for the low solubility.

OBJECTIVE: To investigate the intestinal absorption characteristics of curcumin hydroxypropyl-β-cyclodextrin and curcumin in rats.
METHODS: The curcumin hydroxypropyl-β-cyclodextrin was prepared by grinding method, and the solubility of curcumin hydroxypropyl-β-cyclodextrin and curcumin was detected. Twelve male Sprague-Dawley rats were used to establish a one-way perfusion model of intestinal segment (duodenum, jejunum, ileum and colon), and randomly divided into two groups. The experimental group was given curcumin hydroxypropyl-β-cyclodextrin, and the control group was perfused with curcumin suspension. The absorption rate (Ka) and effective permeability (Papp) of curcumin hydroxypropyl-β-cyclodextrin and curcumin at each intestinal segment were measured by ultraviolet-visible spectrophotometry.

RESULTS AND CONCLUSION: The solubility of curcumin hydroxypropyl-β-cyclodextrin in water was increased by 33.68 times compared with that of curcumin. The absorption rate constant (Ka) of curcumin hydroxypropyl-β-cyclodextrin was ranked as follows: duodenum > ileum > jejunum > colon, and the effective permeability (Papp) was ranked as follows: colon > duodenum > ileum > jejunum, and the absorption in the intestines was significantly higher than that of curcumin (P < 0.05). In summary, curcumin hydroxypropyl-β-cyclodextrin can obviously improve the absorption of curcumin in the intestines of rats.
