Abstract

Aim of this study was to evaluate the total phenolic content (TPC), total flavonoids content (TFC), antioxidant and antibacterial activities of fruits, leaves and peels of locally available citrus species. Result revealed that TPC and TFC of the fruit, leaves and peels range from 6.1 to 34.22 mg GAE/ g DW and 1.71 to 28.96 mg QUE/g DW, respectively. Highest TPC and TFC were Citrus medica leaves. Furthermore, range of antioxidant activities of the fruits, leaves and peels range were analyzed using DPPH scavenging as well as reducing power assays. Both analysis revealed that Citrus maxima leaves, Citrus aurantum Peels and Citrus medica leaves have the highest antioxidant activities with IC50 values 54.86 ± 0.09, 56.69 ± 0.08 and 66.81 ± 0.03 µg/ml, respectively. Furthermore, analyzed plant extract revealed the range of antibacterial activities in both grams positive and gram negative bacteria. Our results revealed that not only fruits, and leaves but also peels showed significant biological activities.

尼泊尔Kavre地区柑橘叶、皮和果实的总酚含量、类黄酮含量、抗氧化和抗菌活性

本研究旨在评价当地柑橘品种果实、叶片和果皮的总酚含量(TPC)、总黄酮含量(TFC)、抗氧化和抗菌活性。结果表明，果实、叶片和果皮的TPC和TFC含量分别为6.1 ~ 34.22 mg GAE/ g DW和1.71 ~ 28.96 mg QUE/g DW。TPC和TFC最高的是柑橘叶。此外，通过DPPH清除和还原力测定，分析了果实、叶片和果皮的抗氧化活性范围。结果表明，大黄柑叶、金黄柑皮和金黄柑叶的抗氧化活性最高，IC50值分别为54.86±0.09、56.69±0.08和66.81±0.03µg/ml。此外，分析了植物提取物对革兰氏阳性菌和革兰氏阴性菌的抗菌活性范围。结果表明，不仅果实和叶片，果皮也具有显著的生物活性。
