PENGUJIAN AKTIVITAS ANTIOKSIDAN EKSTRAK BUNGA LOTUS (Nelumbo nucifera)
Abstract: The purpose of this
research was to observe antioxidant activity of lotus leaves extract (Nelumbo
nucifera). The extraction process was
carried out using three different solvents namely methanol, ethyl acetate and
n-hexane. The observed parameters were extraction yields phytochemical
compounds (alkaloid, flavonoid and tanin) and antioxidant activity using DPPH
method. The results showed that the methanol extract exhibited the highest
yield with a value of 0.708% and had a flavonoid tannin content of 1161 ppm.
The antoxidant activity of the same extract as indicated by IC50 value was 199
ppm. The extract ethyl acetate and n-hexane solvents did not show potential
antioxidant activities.
