【 摘 要 】

The utilization of mangrove plants as traditional medicinal ingredients has long been utilized by the community for treatment of various diseases in favour of bioactive components from its secondary metabolites. Secondary metabolites from mangroves could act as an antioxidant to prevent oxidative stress. Mangrove may contain endophytic microbes in its tissues that are capable of producing secondary metabolites. In theory, endophytic microbes isolated from a plant can produce secondary metabolites similar to those of the original plants or even in relatively high numbers. In this research, two mangrove species Avicennia marina and Xylocarpus granatum from Serang, Banten province, samples have been taken to investigate the antioxidant activities of its extracts. Furthermore, isolation of endophytic microbes from both mangroves had been done. This research succeeded to isolate six fungi and three bacteria as endophytic microbes. Meanwhile, the highest extraction yield was obtained by the leaves of A. marina that is approximately 3% (w/w), whereas mangroves' endophytic microbe highest extract yield was obtained by bacteria from fruits of A. marina 18 mg/100 mL media. For antioxidant activities, the highest activities were obtained by fungi within the stems and the roots of A. marina, also additionally fungi in the leaves of X. granatum.
