本文首次报道了一种极性化学标记物没食子酸甲酯的分离纯化。该化合物通过开放柱色谱法分离和纯化。使用分析型薄层色谱法（TLC）监测化合物的分离。使用气相色谱质谱直接进样探针（GCMS DI-探针）进一步分析所获得的纯化合物，同时使用核磁共振（NMR）光谱仪通过进行各种分析如1H、13 C
This paper describes for the first time the isolation and purification of a polar chemical marker known as methyl gallate from Labisia pumila leaves. This compound was isolated and purified through an open column chromatography. Analytical thin layer chromatography (TLC) was used to monitor the separation of the compound. The pure compound obtained was further analyzed using gas chromatography mass spectrometry direct injection probe (GCMS DI-probe) while identification of the structure was performed using nuclear magnetic resonance (NMR) spectroscope by conducting various analysis such as 1 H, 13 C
