homalomena aromatica/이산화 규소

Column chromatography on silica gel and Sephadex LH-20 was used to study the chemical constituents of Homalomena occulta. The chemical structures of the separated compounds were elucidated by spectroscopic data analyseS. Twelve compounds were obtained and identified as 5-pentylresorcinol-b-glucoside

Twelve compounds were isolated from alcohol extracts of the rhizome of Homalomena occulta by using various chromatographic techniques including column chromatography onsilica gel and C₁₈ reverse-phase silica gel, and semi-preparative HPLC. Their structures were identified by physico-chemical

OBJECTIVE Bio-active constituents were expected to abstain from Homalomena occuta. METHODS Extracts from the plant with 95% alcohol were distributed by several solvents and isolated via column chromatography on silica and Saphadex 20-LH gel. RESULTS Thirteen compounds were isolated from this plant.
