Phytochemical investigation of antioxidative components from the murraya leaves / Norhakimy Majid

Murraya koenigii is a plant that contains antioxidant which can acts as beneficial
to human. Study about the antioxidative compound in Murraya was done. Crude
of the extract was examined to identify the antioxidative compound by qualitative
and quantitative. Qualitative result was done by using Thin Layer
Chromatography (TLC) analyzed by spraying reagent. Quantitative result was
tested by using various concentrations which are 3.125, 6.25, 12.5,25, 50 and 100
µg / mL and it was analyzed by UV spectrophotometer. The strongest scavenging
activity was petroleum ether while the lowest scavenging activity was
dichloromethane. Secondary metabolites of Murraya that have been detected were
terpenoid which correlated with the presence of antioxidant at Rӻ value 0.561,
0.622 and 0.917. Secondary metabolites that exhibit positive result of
phytochemicals are tannins, alkaloids, flavonoid and terpenoids. Structures that
had been obtained from dichloromethane extract were from different Rf. The
structures were nonanoic acid, 9 - oxo -, methyl ester, estra - 1,3,5 (10) - trien17β
- 01 and oleic acid from Rӻ 0.561. Rӻ 0.622 showed structures Hexadecanoic
acid, 1 - (hydroxymethyl) - 1, 2 - ethanediyl ester and 1 - phenanthrenecarboxylic
acid 1 ,2 ,3 ,4a ,5 ,6 ,7 ,8 ,9 ,10 ,10a - dodecahydro - 1, 4a - dimethyl- 7 - (1 methylethyl)
-, methyl ester, [IR - (1<1 ,4ap ,7P ,1Oa(1)] -. The structure obtained
from Rӻ 0.917 were butylaldehyde, 4 - benzyloxy - 4 - [2, 2, - dimethyl - 4 dioxolanyl
and 2 - piperidione, N - [4 - bromo - n - butyl].
