SENYAWA METABOLIT SEKUNDER TUMBUHAN LITSEA GLUTINOSA MADANG

SECONDARY METABOLITE COMPOUND PLANT Litsea glutinosa madang

Author :
SABLI, ACHMAD SANDI 




ABSTRAK

Senyawa terpenoid dan turunan sinamat yang disarankan sebagai -Amirin dan isopentil 3-4-metoksifenil propanoat telah diisolasi dari ekstrak n-heksana kulit batang tumbuhan Litsea glutinosa madang. Isolasi dan fraksinasi dilakukan secara ekstraksi maserasi kromatografi lapis tipis KLT kromatografi cair kolom vakum KCKV kromatotron dan rekristalisasi. Identifikasi struktur dilakukan berdasarkan data spektroskopi ultra violet UV infra merah IR spektroskopi 13C-NMR dan spektroskopi 1H-NMR. Aktivitas biologi kedua senyawa ditunjukkan oleh nilai LC50 sebesar 9861 ppm untuk senyawa isopentil 3-4-metoksifenil propanoat dan 19842 ppm untuk senyawa -Amirin dengan metode BSLT dan nilai LC50 sebesar 16728 ppm untuk senyawa isopentil 3-4-metoksifenil propanoat dan 23102 ppm untuk -Amirin dengan larva instar III Aedes aegypti.


ABSTRACT

Terpenoids and cinnamate derivates suggested as -Amyrin and isopentyl 3-4-methoxyphenyl propanoate were isolated from hexane extract of the stem bark of Litsea glutinosa madang. The methods used in this research included maseration extraction and fractination using thin layer chromatography TLC Liquid column vacuum chromatography chromatotron and recrystalization. The structure identification of these compounds were established using the ultra violet UV spectroscopy infra red IR spectroscopy 13C-NMR spectroscopy and 1H-NMR spectroscopy. Bioactivities both compounds were shown by the LC50 values i.e. 9861 ppm for isopentyl 3-4-methoxyphenyl propanoate and 19842 ppm for -Amyrin with Brine Shrimp Lethality Test BSLT using Artemia salina L. and the LC50 values i.e. 16728 ppm for isopentyl 3-4-methoxyphenyl propanoate and 23102 ppm for -Amyrin insecticide assay using larva instar III Aedes aegypti.
