Abstract/Summary
The dichloromethane extract of the air-dried leaves of Syzygium samarangense (Blume) Merr. & Perry afforded 2,4-dihydroxy-3-methyl-6-methoxychalcone (MK11), 24-dihydroxy-3,5-dimethyl-6-methoxychalcone(MK6), 2-hydroxy-3- methyl-4,6-dimethoxychalcone(MK5), squalene(MK9), betulin(MK13), sitosterol(MK12), lupeol(MK7), cycloartenyl stearate[MK10(1)], lupenyl stearate[MK10(2)], sitosteryl stearate [MK10(3)] and 24-methylenecyloartenyl stearate[MK10(4)]. MK10 was obtained as a mixture of triterpenes esterified with stearate. Due to the similarity in the polarity of the compounds in MK10, it is not possible to separate them through normal phase gravity column chromatography.
