Plant derived pharmacologically active compounds have gained importance in food and pharmaceutical industries. The aim of the present study is to identify and study the antioxidant, antimicrobial properties of the phytochemicals present in the crude extract of Eugenia caryophyllus flower buds. The antioxidant activity of the methanol, acetone and chloroform extract was evaluated by 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay. The methanol extract showed better radical scavenging activity than other selected solvents. Preliminary screening of phytochemicals was carried out in methanol extract and total phenol content was found high. Antibacterial activity was determined by well diffusion assay and methanol extract was found effective against Klebsiella pneumonia. FTIR and GC-MS results indicate the presence of aromatic compounds and major constituents were found to be eugenol and eugenyl acetate. Results of this study implied that Eugenia caryophyllus flower bud extract could be considered as health nutriments in food and pharmaceutical industries.
植物源药理活性化合物在食品和制药行业中日益重要。本研究的目的是鉴定和研究丁香花芽粗提物中植物化学物质的抗氧化和抗菌特性。通过1,1-二苯基-2-苦基肼(DPPH)法评估甲醇、丙酮和氯仿提取物的抗氧化活性。甲醇提取物显示出比其他选定溶剂更好的自由基清除活性。对甲醇提取物进行了植物化学物质的初步筛选,发现总酚含量较高。通过打孔扩散法测定抗菌活性,发现甲醇提取物对肺炎克雷伯菌有效。傅里叶变换红外光谱(FTIR)和气相色谱-质谱联用(GC-MS)结果表明存在芳香族化合物,主要成分被发现为丁香酚和乙酸丁香酯。本研究结果表明,丁香花芽提取物在食品和制药行业中可被视为健康营养物质。
