Abstract :
Indonesia is rich in various types of plants, either as medicine or food. One
of the plants that can be developed as medicine or nutritious food is coriander
leaves. Coriander leaves contain flavonoid compounds that have the potential as
antioxidants. This study aims to determine the comparison between the total
flavonoid content of the 70% ethanol extract and the aqueous extract of the leaves
and coriander seeds.
Coriander leaves and seeds were extracted by maceration and infundation
methods, maceration method using 70% ethanol, while infundation using water
heated at 90°C for 15 minutes. TLC with glacial acetic acid as mobile phase:
butanol: water (5:4:1). Determination of flavonoid levels was carried out using
UV-Vis spectrophotometry using AlCl3 method.
The identification results showed that samples of ethanol and water
extracts of coriander leaves and coriander seeds contained flavonoid compounds.
The TLC test showed that the ethanol and aqueous extracts of coriander leaves
and coriander seeds had yellow spots indicating the presence of flavonoids.
Determination of the levels of flavonoids contained in the ethanol extract and
water of coriander leaves and coriander seeds were 2,538±0.0037%QE;
2.466±0.0037%QE; 2.048±0.0037%QE and 2.2547±0.0022 %QE. In the t test test
of ethanol extract 70% of coriander leaves and ethanol extract of 70% of
coriander seeds obtained a significance of 0.956 0.05, it is said that there is no
significant difference
