UV-C IRRADIATION ENHANCED TOTAL PHENOLIC CONTENTS AND ANTIOXIDANT CAPACITY OF MUSA AAA 'BERANGAN'

Potential of UVC germicidal irradiation in suppressing crown rot disease, retaining postharvest quality and antioxidant capacity of Musa AAA “Berangan” during fruit ripening

Crown rot caused by fungal pathogen is the most prevalent postharvest disease in banana fruit that results significant economic losses during transportation, storage, and ripening period. Antifungal effects of ultraviolet C (UVC) irradiation at doses varied from 0.01 to 0.30 kJ m-2 were investigated in controlling postharvest crown rot disease, maintenance of fruit quality, and the effects on a...

Antioxidant capacities and total phenolic contents increase with gamma irradiation in two types of Malaysian honey.

Two types of monofloral Malaysian honey (Gelam and Nenas) were analyzed to determine their antioxidant activities and total phenolic and flavonoid contents, with and without gamma irradiation. Our results showed that both types of honey can scavenge free radicals and exhibit high antioxidant-reducing power; however, Gelam honey exhibited higher antioxidant activity (p < 0.05) than Nenas honey, ...

Antioxidant Capacities and Total Phenolic Contents Enhancement with Acute Gamma Irradiation in Curcuma alismatifolia (Zingiberaceae) Leaves

The present study was conducted in order to assess the effect of various doses of acute gamma irradiation (0, 10, 15, and 20 Gy) on the improvement of bioactive compounds and their antioxidant properties of Curcuma alismatifolia var. Sweet pink. The high performance liquid chromatography (HPLC) and gas chromatography (GC) analysis uncovered that various types of phenolic, flavonoid compounds, a...

Total phenolic (flavonoids) contents and antioxidant capacity of different Murraya koenigii (L.) Spreng. extracts

In the present study, antioxidant activities of the three plant parts (stem, leaf and callus) were investigated. Ethanolic extracts of stem, leaf and callus powder was characterized by the method described by (Hatano et al., 1988) in which stable 1, 1-diphenyl-2-picrylhydrazyl (DPPH) free radical solution was used. In this paper, it is found that all of the in vitro and in vivo extracts have re...
