| 中文摘要： | 目的 研究诃子不同温度炮制品的化学成分含量变化，并比较其抗溃疡性结肠炎（UC）的效果。方法采用砂烫法制备不同温度（160、180、200、220、240、260、280、300℃）诃子炮制品。采用高效液相色谱法检测诃子生品和不同温度炮制品中没食子酸、诃黎勒酸、诃子酸、鞣花酸的含量。将小鼠分为空白组、模型组、美沙拉嗪肠溶片组（阳性对照，0.4g/kg）和诃子生品及不同温度炮制品组（诃子各组给药剂量均为1.3g/kg），每组10只。除空白组外，其余各组小鼠均从肛门一次性注入6％乙酸0.1mL，以复制UC模型。造模成功后，空白组和模型组小鼠灌胃水，其余各组小鼠均灌胃相应药液，给药体积均为20mL/kg，每天1次，连续7d。观察各组小鼠一般体征并记录体质量，检测其结直肠长度、结直肠指数及血清中炎症相关指标[超氧化物歧化酶（SOD）、丙二醛（MDA）、白细胞介素10（IL-10）、IL-1β、肿瘤坏死因子α（TNF-α）]的水平，观察结直肠病理形态学变化，并进行药效综合评分。结果随着炮制温度的升高，诃子中诃黎勒酸、诃子酸含量逐渐降低，没食子酸含量先增加再降低，鞣花酸含量逐渐增加。与模型组比较，诃子生品和不同温度炮制品组小鼠一般体征、体质量、结直肠长度、结直肠指数及炎症相关指标水平大部分均显著改善（P＜0.05或P＜0.01），结直肠组织腺体隐窝结构被修复，炎症细胞浸润减少，且在260℃条件下制得的炮制品的药效综合评分最高。结论诃子经不同温度炮制后化学成分含量变化显著，且抗UC的效果存在差异，其中在260℃条件下制得的炮制品效果最优。 |
| 英文摘要： | OBJECTIVE To study the content changes of ch emical constituents of processed products of Terminalia chebula at different temperatures ，and to compare its anti-ulcerative colitis effect. METHODS Processed products of T. chebula at different temperatures（160，180，200，220，240，260，280，300 ℃）were prepared by sand scalding technology. HPLC method was adopted to determine the contents of gallic acid ，chebulagic acid ，chebulinic acid and ellagic acid in crude drug and processed products of T. chebula at different temperatures. The mice were divided into blank group ，model group ，Mesalazin enteric-coated tablets group （positive control ，0.4 g/kg），crude drug and processed products groups of T. chebula at different temperatures （1.3 g/kg），with 10 mice in each group. Except for blank group ，other groups were given 6％ acetic acid 0.1 mL via anus to induce ulcerative colitis model. After modeling ，blank group and model group were given water intragastrically ，and other groups were given relevant drug intragastrically ，20 mL/kg，once a day ，for consecutive 7 days. The general physical signs of mice in each group were observed and the body weight was recorded. The colorectal length and index ，serum levels of related inflammation indexes [superoxide dismutase （SOD），malondialdehyde （MDA），interleukin-10 （IL-10），IL-1 β ，tumor necrosis factor α （TNF-α）] were detected. The pathomorphological changes of colon and rectum were observed ，and the comprehensive score of pharmacodynamics was performed. RESULTS With the increase of processing temperature ，the contents of chebulagic acid and chebulinic acid decreased gradually ，the content of gallic acid increased first and then decreased ，and the content of ellagic acid increased. Compared with model group ，the general physical signs ，body weight ，colorectal length ，colorectal index and related inflammation indexes were all improved significantly in crude drug and processed products groups of T. chebula at different temperatures（P＜0.05 or P＜0.01）. The glandular recess structure of colorectal tissue was repaired ，the infiltration of inflammatory cells was reduced ，and the comprehensive score of efficacy of processed products prepared at 260 ℃ was the highest. CONCLUSIONS The contents of chemical components in T. chebula processed at different temperatures change significantly and their anti-ulcerative colitis effects are different. The processed products of T. chebula prepared at 260 ℃ show the best anti-ulcerative colitis effect. |
