Ampas jahe merupakan salah satu limbah yang dihasilkan dari proses penyulingan minyak jahe. masih mengandung atsiri, gingerol, shogaol, dan resin sehingga ampas berpotensi untuk dimanfaatkan menjadi oleoresin. Tujuan percobaan ini adalah mengkaji pengaruh perbedaan konsentrasi etanol terhadap karakteristik oleoresin merah serta memperoleh pelarut terbaik berdasarkan hasil uji organoleptik. diek...

Abstract This study aims to determine differences in oleoresin production and the type content of turpentine P. oocarpa merkusii. The first stage research activity was collect obtained from 15 plants each pine aged 14 years which were determined randomly. Determination phytochemicals, especially using Gas Chromatography-Mass Spectrometry by injecting gas-phase chemical isolates. tapping data an...

ABSTRACT Copaiba oleoresin, extracted from the Copaifera reticulata tree, has been used as a remedy in popular medicine Brazilian Amazon for various purposes, including reducing drug abuse. Yet no studies evaluated effect of repeated administration copaiba oil on alcohol consumption animals. To evaluate this effect, we divided adult male Wistar rats into a) an group which animals had free acces...

In an analysis of Australian grown P. radiata marked changes were found in the relative proportions and compositions of the resin acids. fattY acids, and fatty acid esters associated with heartwood formation. While the proportion of resin acids increased substantially in the heartwood, there was little change in resin acid composition from outer sapwood to inner heartwood. Extracts from wood of...

Zingiber officinale Rosc, commonly called Ginger, is an underground rhizome widely used as a spice in the food and beverage industries. The prominent bioactive component of ginger [6]-gingerol. present study focuses on influence variety maturity stage [6]-gingerol content. Ten authentic cultivars were collected from ICAR-Indian Institute Spice Research, Calicut, Kerala, India analyzed for oleor...

Oleoresin samples collected directly from living-trees by three different tapping methods, and four geographical origins were analyzed using two gas chromatography (GC) methods. The GC was coupled to a flame ionization detector (GC-FID) for quantification, mass spectrometer (GC-MS) identifying the chemical composition. Twenty-eight components detected quantified. proportions of each component v...
