本研究采用2,2 -二苯基-1-苦酰肼（DPPH）清除率测定、总酚含量测定（TPC）和铁还原抗氧化能力测定（FRAP）方法，研究了10种印度药用植物（番石榴石蕊、芒果、长叶蓼、洋葱、甘菊、山楂、蓖麻、角Physalis angulata、Ixora coccinea和玫瑰长春花）的乙醇和水提取物的抗氧化和抗菌潜力。在DPPH清除实验中，番石榴醇提物对自由基的清除作用最高（94.48±0.07），角Physalis醇提物对自由基的清除作用最低（9.58±0.65）。TPC值和FRAP值具有相似的变化趋势，红藤乙醇提取物最高（427.25±0.86），554.93±2.37)，玫瑰长春花水提取物最低（41.04±1.58），角Physalis乙醇提取物最低（111.94±6.34）。所有植物提取物均表现出较强的清除率和还原力，且呈剂量依赖性。从抗氧化筛选中筛选出活性最高的5种植物提取物进行抗菌研究。对3种病原菌嗜水气单胞菌（MTCC 1739）、黄体微球菌（MTCC 106）和创伤弧菌（MTCC 1145）分别进行了单独和联合抑菌试验，结果表明，各植物提取物均表现出不同程度的抑菌活性。因此，根据研究结果，所测试的植物材料可以作为抗氧化剂有效地保护自由基，并有可能在动物饲料中得到利用
The study examine the antioxidant and antimicrobial potential of the ethanolic and aqueous leaf extracts of ten selected Indian medicinal plants namely, Psidium guajava, Mangifera indica, Polyalthia longifolia, Allium cepa, Phyllanthus amarus, Thespesia populnea, Ricinus communis, Physalis angulata, Ixora coccinea, and Vinca rosea using 2, 2-Diphenyl-1-picrylhydrazyl (DPPH) scavenging assay, total phenol content (TPC) and ferric reducing antioxidant power assay (FRAP) methods. In DPPH scavenging assay, the highest radical scavenging effect was found in ethanolic extract of Psidium guajava (94.48±0.07) and the least in ethanolic extract of Physalis angulata (9.58±0.65). The TPC and FRAP value followed similar trend with highest found in Ixora coccinea ethanolic extract (427.25±0.86), (554.93±2.37) and lowest in Vinca rosea aqueous extract (41.04±1.58) and Physalis angulata ethanolic extract (111.94±6.34) respectively. All the plant extracts showed strong scavenging and reducing power in a dose dependent manner. From the antioxidant screening, five plant extracts with highest activity were selected for antibacterial study. The plant extracts were tested against three pathogenic bacteria Aeromonas hydrophila (MTCC 1739), Micrococcus luteus (MTCC 106) and Vibrio vulnificus (MTCC 1145) individually and in combination, and all the extracts exhibited varying level of antibacterial activity. Therefore based on the results obtained from the study the plant materials tested may act as an antioxidant agent for effective protection from free radicals and potential utilization in animal feed as
