Abstract

Ethyl acetate fraction of Myrmecodia tuberosa (non Jack) Bl. expressed potential immunomodulatory effect in preliminary study. This study was aimed to determine the stimulation index of each subfraction towards lymphocyte of BALB/C mice by in vitro technique and to explore the activityof lymphocyte proliferation correlated to total phenolic contents. lymphocyte proliferation assay was performed by MTT. Determination of total flavanoid content was done by a colorimetric method while the total phenolic was tested by the Folin-Ciocalteu method. The result showed stimulation index profile was positively correlated with the total flavanoid content( R2 = 0,606) while weak correlation was observed on the total phenolic content (R2 = 0,167).

Abstract

Myrmecodia pendens Merr & Perry (Rubiaceae) is widely used in Papua as traditional medicine against various diseases. Preliminary study revealed that ethyl acetate fraction has potency to increase mice Balb/c lymphocyte proliferation in vitro. This study aimed to investigate the active compound responsible for the activity. Dried powders of plant tubers were macerated in ethanol 95% followed by solvent evaporation. The crude extract was further fractionated by liquid-liquid partition with n-hexane, ethyl acetate and water, successively. The ethyl acetate fraction was subjected to a silica gel column and separated by vacuum. The subfraction yields were tested on mice Balb/c lymphocytes to observe the influence on lymphocyte proliferation by MTT assay. Total phenolic content of subfractions were determined by Folin-Ciocalteau method. Chemical characteristics of active compound was identified by GC-MS, UV-Vis spectroscopy, IR and H-NMR. The result showed that total phenolic content has no significant correlation to the lymphocyte proliferation activity. Subfraction 7 yielded from ethyl acetate-methanol (7:3v/v) contained a major constituent (78% by GCMS, 83.75% by Densitometry). GCMS and UV spectra suggested a phenolic substructure. IR and H-NMR suggested that the phenolic was glycosilated and had aliphatic moiety.
