Isolation and screening of the endophytes possessing antioxidant activity from Rutaceae and Zingiberaceae plants

Abstract

Zingiberaceae and Rutaceae have been many applications in the treatment of diseases. Their leaves, stems, rhizomes and fruits… containing essential oils which could offer useful habitats for different endophyte groups. In this research, the strains of endophyte Streptomyces sp., Aspergillus terreus, Cladosporium sp., Penicillium sp. were isolated from different plant parts of galangal, ginger, laurel and their antioxidant activities were determined. The antioxidant activity by using DPPH methos applied on these strain was with the following results: R-TN3 strain showed the highest antioxidant activity (62.32 %), followed by G1- TL3 and NQ-TN3 and the T-TG3 was the lowest (30.95 %).
