Biodiesel Production of Garcinia Mangostana Linn. seeds by Two-Phase Solvent Extraction and Alkali-Catalyzed Transesterification

Abstract

Abstract-The present study introduced the potential used of Garcinia Mangostana Linn. seeds as feedstock for bio-diesel production. The preparation of biodiesel by two-phase solvent extraction (TSE) and alkali-catalyzed transesterification was studied. The important factors including catalyst concentration, ratio of methanol to oil and temperature on conversion FAME were examined respectively by experiments. The results of two-step transesterification showed that the optimal conversion of Garcinia Mangostana Linn. seeds into fatty acid methyl ester (FAME) were at condition of 4:1 methanol/oil volume ratio, 50 o C reaction temperature, 0.5% ( catalyst / oil weight ratio w/w) solid base catalyst amount and at 5 minutes reaction time.

Mangosteen pericarp extract embedded in electrospun PVP nanofiber mats: physicochemical properties and release mechanism of α-mangostin

“…20 Alkene groups in the MPE were confirmed by the presence of peaks at 838 and 583 cm -1 for =C-H bending. 53 The characteristic peaks of PVP were noticed in the FTIR spectrum of MF0 nanofiber mat: O-H stretching at around 3,420 cm -1 , C=O stretching at 1,653 cm -1 , and C-N stretching at 1,288 cm -1 . 54,55 Asymmetric stretching of CH 2 in PVP chain was shown by the moderate peak at 2,952 cm -1 .…”

Analisis Komposisi Biodiesel Hasil Konversi Minyak Biji Carica (Carica pubescens) Menggunakan Enzim Lipase Bekatul

“…Minyak nabati atau hewani yang dapat dibudidayakan dan kemudian dipanen memberikan sifat terbarukan bagi biodiesel. Beberapa penelitian telah dilakukan untuk memproduksi biodiesel dari minyak nabati yaitu dari minyak kapuk randu [2], minyak jarak pagar [3], minyak kemiri [4], minyak biji kapuk [5], minyak kacang kedelai [6], minyak biji manggis [7], minyak biji karet [8], minyak biji apokat [9], minyak biji papaya dan biji rambutan [10].…”

Microstructural Characterization of the Garcinia mangostana Fruit at Different Maturity Level

“…Garcinia mangostana L. (Clusiaceae), commonly known as mangosteen, have been used as a traditional medicine in Southeastern Asia for the treatment of diarrhea, dysentery, inflammation, ulcers and wound healing 2,3 . Mangosteen is cultivated mainly in Indonesia, Malaysia, Philipina and Thailand [4][5][6] . Medicinal properties of G. mangostana are associated with its bioactive compounds, xanthone.…”
