Aromatic plants from Vetnam, sources of natural products for industry

Abstract

aromatic plants produce by vapour distillation or other processes essential oils which are products with high commercial value used in the natural product industries such flavour and fragrance, perfumes and cosmetics industries as well as pharmaceutical industry. The aim of this study was to characterise some aromatic plants from Vietnam through the chemical composition of their essential oils. We got interested in essential oils which contained a main component with high to ultra high content, susceptible to find an industrial use. For this study, a dozen of plants have been selected. The composition of their essential oils will be compared with those of the same plants, reported in the literature, from Vietnamese origin or from other countries.

A Study on Synthesis of para-menthane-3,8-diol (PMD) - A Safe Mosquito Repellent Active Ingredient

“…The citronellal content in lemon eucalyptus essential oil used in this study was different from other studies. Specifically, the citronellal content in this study was lower than the results reported in Vietnam by Tran Minh Hoi et al (78.2%) [13], and Ho Dung Manh et al (78.6%) [14], higher than the results reported by Tran Thi Nhu Trang et al (62%) [15]. In addition, the citronellal content in this study was lower than the citronellal content (74%) in the lemon eucalyptus essential oil used to synthesize PMD in the study of Jeremy Drapeur et al [6].…”

“…NMR spectra were recorded on a Bruker (AvanceNEO). 1 H and 13 C spectra were determined at 600 and 150 MHz, respectively, and were recorded in CDCl3. NMR spectral data of PMD: C NMR 20.3 (CH2), 22.2 (CH3), 25.5 (CH), 28.6 (CH3), 28.9 (CH3), 34.9 (CH2), 42.5 (CH2), 48.2 (CH), 67.9 (CH), 73.2 (C).…”
