The objective of this study was to carry out preliminary
phytochemical screening and to determine the total phenolic,
flavonoid, flavonol contents and antioxidant activities (by
DPPH, ABTS and FRAP) of G. velutinus collected from the
rainforest of Brunei Darussalam. To date there has been no
study being conducted on G. velutinus collected from Brunei
Darussalam. Further, to the best of our knowledge, there
has been no previous work being published on the phytochemical
screening and antioxidant activities of G. velutinus.
