In:
International journal of pharmacy and pharmaceutical scienceSummary: Objective:
To investigate the content and antioxidant activiti
es of polyphenol, the correlation between polypheno
l content and their antioxidant
activities, and phytochemistry compositions of diff
erent extracts from marine sponge
Aaptos suberitoides
commonly found growing in Nhatrang bay,
Vietnam orienting application into functional food
and pharmacy.
Methods:
Evaluating the toxicity of antioxidant polyphenol
powder preparing from the initial concentrated extr
act was by the adjusted Behrens
Karber method and a correlation between polyphenol
content and antioxidant activities basing on the Pe
arson coefficient in Excel. Separating
antioxidant polyphenol content was base on solvents
polarization of n-hexane, chloroform, ethanol, eth
yl acetate and n-butanol which the
quantification of polyphenol content and antioxidan
t activities, and preliminary phytochemical composi
tions qualitative.
Results:
Antioxidant polyphenol powder did not affect mice w
eight during the assay time of 28 d. Polyphenol con
tent and antioxidant activities got
the highest value at chloroform extract in comparis
on to other extracts, a significant difference (p<0
.05) and strong correlation (R2>0.9).
Polyphenol content (122.682 mg gallic acid equivale
nt ml-1), total antioxidant activity (368.183 mg as
corbic acid equivalent ml-1), reducing power
activity (24.08 mg FeSO4 equivalent ml-1) and DPPH s
cavenging (72.48±1.54 %) were the highest values. A
lkaloids, flavonoids, steroids, tannins
and triterpenoids existed in initial methanol extra
ct. Weakly polarized polyphenol content was 70.27%
in comparison to initial methanol extract.
