DPPH antiradical assay
The EC50 values on the effect of extracts of C. albidum on
DPPH scavenging activity showed that petroleum ether
(4057.5 ± 809.6 g/kg) had the least antiradical activity
while ethyl ether (414.4 ± 92.0 g/kg) had the highest
activity (fig. 2). Similarly, the EC50 values of myricetin 3-
rhamnoside (TCA-3) and vitamin C (standard control)
were 314.1 + 60.2 and 127.1 ± 8.6 g/kg respectively (fig.
2). The order of scavenging activity is such that myricetin
3- rhamnoside > ethylacetate extract > n-butanol extract >
ethanol extract > petroleum extract.

DPPH antiradikal assay
Nilai EC50 tentang pengaruh ekstrak C. albidum pada
aktivitas scavenging DPPH menunjukkan bahwa petroleum eter
(4057,5 ± 809,6 g / kg) memiliki aktivitas paling antiradikal
sementara etil eter (414,4 ± 92,0 g / kg) memiliki tertinggi
kegiatan (gbr. 2). Demikian pula, nilai-nilai EC50 dari myricetin 3-
rhamnoside (TCA-3) dan vitamin C (kontrol standar)
yang 314,1 + 60,2 dan 127,1 ± 8,6 g / kg masing-masing (gbr.
2). Urutan aktivitas scavenging adalah seperti yang myricetin
3- rhamnoside> ekstrak ekstrak etilasetat> n-butanol>
ekstrak etanol> ekstrak minyak bumi.
