Secondary metabolites from the leaves of Syzgium samangense
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(...
