Dua Dimer Resveratrol dari Kulit Batang Shorea parvifolia (dipterocarpaceae)

Abstract

Two resveratrol dimers, (-)-ampelopsin F dan (-)-laevifonol were isolated from aceton extract of the stem bark of Shorea parvifolia. The structures of these compounds were determined based on their spectroscopic data including spectroscopy ultra violet (UV), infra red (IR), nuclear magnetic resonance ( 1 H-NMR, 13 C-NMR) and also were compared to the reported data.

Phytochemical and pharmacological profile of genus shorea: A review of the recent literature

“…Resveratrol trimers reported to be isolated from different species of Shorea plants include (+)-α-viniferin [ 22 ], hemsleyanol B [ 23 ], (−)-viticanol A [ 24 ], shoreanol A [ 25 ] , shoranol B [ 26 ], (−)-davidiol A [ 27 ], ampelopsin E [ 28 ], (−) ampelopsin E [ 29 ], pauciflorol A [ 30 ], diptoindonesin C [ 31 ], gnetin H [ 32 ], (−)-α-viniferin [ 33 ], viticanol G [ 34 ], stenophyllol [ 35 ] , viticanol A [ 36 ], suffruticosol [ 37 ], viticanol E [ 38 ], davidiol A [ 39 ] and caragaphenol A [ 45 ] ( Fig. 4 ).…”

“…The highest form of resveratrol oligomers isolated from Shorea species is resveratrol tetramers containing four stilbene units. The resveratrol tetramers isolated from various species of Shorea include hopeaphenol [ 40 ] shorea ketone [ 41 ], grandiphenol [ 42 ], (−)-hemsleyanol D [ 43 ], diptoindonesin F [ 44 ], distichol [ 45 ] , viticanol C [ 46 ], hopeaphenol A [ 47 ], isohopeaphenol [ 48 ], (−)-ampelopsin H [ 49 ], hemsleyanol C [ 50 ], hemsleyanol D [ 51 ], (−)-hopeaphenol [ 52 ] and viticanol B [ 53 ] , shoreaplatyclaphenols A [ 95 ] , shoreaplatyclaphenols B [ 96 ] ( Fig. 5 ).…”
