Abstract

Dua senyawa oligomer resveratrol, (-)-?-viniferin (2) dan (-)-?-viniferin (3), bersama-sama satu senyawa turunan asam fenolat, bergenin (1) telah berhasil diisolasi untuk pertama kalinya dari ekstrak aseton kulit batang Dipterocarpus intricatus. Struktur molekul senyawa-senyawa tersebut ditetapkan berdasarkan data spektroskopi UV, IR, 1H-NMR dan 13C-NMR serta perbandingan dengan data sejenis yang telah dilaporkan. Senyawa (-)-?-viniferin (2) dan (-)-?-viniferin (3)menunjukkan aktivitas sitotoksik terhadap sel murin leukemia P-388 dengan nilai IC50 masing-masing sebesar 7,8 dan 17,5 ?g/mL.

Abstract

Dua senyawa oligomer resveratrol yaitu (-)-ampelopsin A dan (-)-?-viniferin, telah berhasil diisolasi untuk pertama kalinya dari ekstrak aseton kulit batang Shorea gibbosa. Struktur senyawa ini telah ditetapkan berdasarkan data spektroskopi UV,IR, 1H NMR, 13C NMR serta melalui perbandingan terhadap data senyawa sama yang telah dilaporkan. Pengujian sifat sitotoksikbterhadap dua senyawa oligomer resveratrol tersebut menunjukkan hasil IC50 berturut-turur adalah 17,0 µg.mL-1 ,dan 18,2 µg.mL-1.

Abstract

Three resveratrol oligomers have been isolated from the stem bark of H. gregaria including a resveratrol trimer i.e. α-viniferin (1), and two resveratrol tetramers i.e. vaticanol B (2) and hopeaphenol (3). These structures were determined by spectroscopic evidence including UV, IR, 1H , 13C NMR and compared with that of the reported data in the literatures. Activities of the compounds were determined toward brine shrimp Artemia salina (toxicity) and murine leukemia P-388 cells (cytotoxicity). The compound 1 is the most active against A. salina (LC50 = 49,0 ± 5,8 μg/mL), and the compound 3 has very active level toward murine leukemia P-388 cells (LC50 = 5,7 ± 0,3 μM).Key words : Resveratrol oligomers, H. gregaria, toxicity, and cytotoxicity.

Abstract

Nine resveratrol oligomers have been isolated from the stem bark of Hopea mengarawan i.e. diptoindonesin D (1), balanocarpol (2), ampelopsin A (3), hopeaphuran (4), heimiol A (5), parviflorol (6), a-viniferin (7), isohopeaphenol (8), and vaticanol B (9).The structures of these compounds were determined based on spectroscopic evidence such as UV, IR, 1-D, 2-D NMR and comparison with the reported data. Those compounds implied that Hopea tends to produce resveratrol dimers. Moreover, in subgenus level, besides ampelopsin A (3) and isohopeaphenol (9), resveratrol oligomers in H. mengarawan the same as in H.dryobalanoides. It indicated that H. mengarawan and H. dryobalanoid.es came from the same subgenus.

Abstract

ABSTRACT Volatile components from leafs of Toona sinensis (Meliaceae) were isolated by distillation water-vapour method and analyzed using GC/MS. Forty-eight component were identified, and eight major components are Germacrene-D, Germacrene-B, α-Terpinene, α-Humulene, β-Caryophyllene,  α-Elemene, Bicyclogermacrene and α-copaene. Insect activity of the essential oil against Crosidolomia pavonana were tested. The activity of the essential oil with concentration 25% (mortality 73.3%), concentration 50% (mortality 83.3%) and concentration 75% (mortality 90%). Keywords : Toona sinensis (Meliaceae), essential oil, Crosidolomia pavonana, and mortality.
