摘要:

目的 探讨生姜、青椒、大蒜、蘑菇、柠檬、山药、葡萄、番茄、西兰花和洋葱10种可食用植物来源外泌样纳米颗粒(ELNs)的体外抗氧化能力及其对过氧化氢诱导PC12细胞氧化损伤的保护作用,为深入研究ELNs提供依据。 方法 将PC12细胞分为对照组、外泌体组、过氧化氢组和过氧化氢+ELNs组。高速差速离心法分离提取10种ELNs,采用二苯基苦基苯肼(DPPH)自由基清除体系、2,2-联氮-二(3-乙基-苯并噻唑-6-磺酸)二按盐(ABTS)阳离子自由基体系和铁离子总还原能力(FRAP)体系检测10种ELNs的体外抗氧化能力,MTT法检测各组PC12细胞活力。 结果 10种ELNs对DPPH自由基的清除能力从高到低依次为蘑菇、洋葱、生姜、柠檬、葡萄、番茄、青椒、西兰花、山药和大蒜。10种ELNs对ABTS阳离子自由基的清除能力从高到低依次为生姜、蘑菇、洋葱、柠檬、山药、葡萄、青椒、大蒜、番茄和西兰花。10种ELNs对FRAP体系的总抗氧化能力从高到低依次为生姜、青椒、洋葱、蘑菇、柠檬、西兰花、葡萄、山药、番茄和大蒜,其中抗氧化能力相对较强的5种ELNs对DPPH自由基、ABTS阳离子自由基的清除能力以及FRAP随着ELNs浓度升高而增大,半数抑制浓度(IC50)值分别为洋葱73.15、123.02和83.00 g·L-1,生姜124.07、91.24和91.24 g·L-1,蘑菇310.44、518.04 和237.10 g·L-1,青椒969.06、847.32 和237.10 g·L-1,柠檬1 718.94、544.38 和962.12 g·L-1;与对照组比较,600 μmol·L-1过氧化氢组PC12细胞活力下降约30%。与过氧化氢组比较,过氧化氢+ELNs组(青椒、柠檬、山药和西兰花)PC12细胞活力明显提高21.08%、26.2%、11.72%和15.15%。 结论 生姜、蘑菇、柠檬和洋葱来源ELNs外泌体在DPPH自由基清除体系、ABTS阳离子自由基体系和FRAP体系中均表现出较强的抗氧化能力。青椒、柠檬、山药和西兰花来源ELNs对过氧化氢诱导的PC12细胞氧化损伤具有保护作用。

Abstract:

Objective To discuss the antioxidant capacities of ten edible plant exosomes-like nanoparticles (ELNs) from ginger, green pepper, garlic, mushroom, lemon, yam, grapes, tomatoes, broccoli,and onions in vitro and their protective effects on oxidative injury of the PC12 cells induced by hydrogen peroxide,and to provide the basis for the further study on the ELNs. Methods The PC12 cells were divided into control group, exosome group, hydrogen peroxide group,and hydrogen peroxide+exosomes group. Ten types of ELNs were separated and extracted by using high-speed differential centrifugation. The in vitro antioxidant capacities of these 10 types of ELNs were detected by using 1,1-diphenyl-2-picryl-hydrazyl(DPPH) free radical scavenging system,2,2'-azinobis-(3-ethylbenzthiazoline-6-sulphonate(ABTS) cationic radical system, and ferric ion total reduction antioxidant power(FRAD) system. The viabilities of PC12 cells in various groups were detected by MTT method. Results The DPPH radical scavenging abilities of ten ELNs,from high to low, were mushroom, onion, ginger, lemon, grape, tomato, green pepper, broccoli, yam, and garlic; the capacities of ten ELNs to scavenge ABTS, from high to low, were ginger, mushroom, onion, lemon, yam, grape, green pepper, garlic, tomato, and broccoli; the total antioxidant capacities of ten ELNs in FRAP, from high to low, were ginger, green pepper, onion, mushroom, lemon, broccoli, grape, yam, tomato,and garlic. The antioxidant capacities of five ELNs with stronger antioxidant capacities were increased with the increasing concentration of the ELNs in the DPPH radical scavenging system, ABTS cationic radical system and FRAP system. The half maximal inhibitory concentration(IC50) values of onion were 73.15, 123.02, and 83.00 g·L-1, the IC50 values of ginger were 124.07, 91.24, and 91.24 g·L-1, the IC50 values of mushroom were 310.44, 518.04,and 237.10 g·L-1, the IC50 of green pepper were 969.06, 847.32,and 237.10 g·L-1 and the IC50 values of lemon were 1 718.94, 544.38,and 962.12 g·L-1; compared with control group, the viability of the PC12 cells in hydrogen peroxide group was decreased by about 30%. Compared with hydrogen peroxide group, the viability of the PC12 cells in hydrogen peroxide+ELNs groups (green pepper, lemon, yam, and broccoli) were increased by 21.08%, 26.2%, 11.72%, and 15.15%. Conclusion The ELNs from ginger, mushroom, lemon, and onion show stronger antioxidant capacities in the DPPH radical scavenging system, ABTS cationic radical system and FRAP system. The ELNs from green pepper, lemon, yam, and broccoli have protective effects on the oxidative damage of the PC12 cells induced by hydrogen peroxide.
