摘　　要：为提高西番莲果皮黄酮的稳定性,并考察其对机体运动的影响。以羟丙基-β-环糊精为壁材、西番莲果皮黄酮为芯材,采用喷雾干燥法制备西番莲果皮黄酮微胶囊,通过单因素与响应面试验确定该微胶囊的最佳制备工艺条件,同时采用动物实验研究其抗运动疲劳活性。结果表明,西番莲果皮黄酮微胶囊的最佳制备工艺条件为:芯壁比为1∶10(g/mL),包埋温度49℃,搅拌时间53 min,进风干燥温度163℃。该条件下制得的西番莲果皮黄酮微胶囊外观略呈球形,大小基本均一,表面完整且光滑,包埋率达84.7%,平均粒径为7.52μm,含水量为3.72%,堆密度为0.51 g/mL,休止角为35.12°。在相同储藏条件下,西番莲果皮黄酮微胶囊中黄酮类化合物的保留率高于其纯化物,表明微胶囊化有助于提高西番莲果皮黄酮的稳定性。通过不同组别小鼠的运动耐力考察指标结果对比分析发现,西番莲果皮黄酮微胶囊可明显延长小鼠的力竭游泳时间,减少运动后血清中乳酸与尿素氮的含量,从而帮助机体进一步提高运动耐力。该研究可为西番莲果皮的利用提供新的思路。In order to improve the stability of flavonoids from passion fruit peel,and investigated its anti-exercise fatigue activity.The microcapsules of flavonoids from passion fruit peel were prepared by spray drying using hydroxypropyl-β-cyclodextrin(HP-β-CD)as wall material,and total flavonoids of passion fruit peel as core material.The preparation conditions of microcapsules of flavonoids from passion fruit peel were confirmed by single factor test and response surface analysis,and investigated anti-exercise fatigue activity in this microcapsule through animal test.The results of single factor tests and response surface analysis indicated that core-to-wall-material ratio was 1∶10(g/mL),embedding temperature was 49℃,stirring time was 53 min and air inlet drying temperature was 163℃as the optimum preparation process.Under these conditions optimized,the microcapsules gained slightly spherical structure,basically uniform size,smooth surface and complete particles,with the embedding rate of 84.7%,the average particle size of 7.52μm,moisture content of 3.72%,bulk density of 0.51 g/mL and repose angle of 35.12°.In the same storage condition,the retention rates of total flavonoids of passion fruit peel microcapsules higher than the purified flavonoid,which showed that microcapsule technology could improve the stability of the flavonoid.Comparing the results of representational indexes of exercise capacity in different mice groups,it revealed that microcapsules of flavonoids from passion fruit peel prolonged the exhaustive swimming time of mice,and decreased the content of lactic acid and urea nitrogen in serum of mice after exercise.Therefore,the microcapsules can help further improve exercise capacity of body,which could provide novel insights for the utilization of passion fruit peel.
