| Summary: | Borneo is the centre of diversity of the genus Durio (family: Malvaceae; local name:
durian). Durian fruit is known to contain high amounts of the major bioactive compounds (as
antioxidants) such as anthocyanins, carotenoids, polyphenols and flavonoids. Two types of
wild durian species, namely Durio kinabaluensis Kosterm. & Soegeng (durian tupoloh) and
Durio oxleyanus Griff. (durian sukang) were studied. The 80% methanolic extracts of flesh,
seed and peel (mesocarp and exocarp) were analysed for antioxidant activities, total phenolic
and total flavonoid content. The antioxidant activities were determined using three parameters;
2,2-diphenyl-1-picrylhydrazyl radical assay (DPPH), 2,2’-Azino-bis (3-ethylbenzothiazoline-6-
sulphonic acid) radical cation assay, and Ferric reducing antioxidant power assay (FRAP).
Durio kinabaluensis mesocarp extract displayed the highest antioxidant properties and total
phenolic content. The non-edible parts of both durians (seed and peel) exhibited higher
phytochemical contents and antioxidant properties compared to the flesh parts. This data may
contribute to the pharmaceutical applications, health benefit information of wild durians and
helps in popularising the potential of these fruits in international markets and ultimately
protects them from extinction. |
