Constituents of Some Essential Oil Bearing Plants from Vietnam

Abstract

Essential oils obtained from hydrodistillation of three medicinal plants grown in Vietnam were analyzed by gas chromatography (GC) and gas chromatography/mass spectrometry (GC-MS). The monoterpene hydrocarbons, α-pinene (50.2%), β-pinene (23.6%) and limonene (5.3%) were the most abundant constituents of the rhizome oil of Zingiber collinsii Mood & Theilade (Zingiberaceae). The main compounds of the stem oil of Croton kongensis Gagnep., (Euphorbiaceae) were benzyl benzoate (12.7%), β-selinene (9.8%), bulnesol (8.0%) and 5,6,7,8-tetrahydroquinoxaline (7.4%). The leaf oil of Goniothalamus albiflous Ban., consisted mainly of α-pinene (26.2%), caryophyllene oxide (10.6%) and 1,8-cineole (9.7%). The composition of the oils of Zingiber collinsii and Croton kongensis was being reported for the first time.

Mosquito Larvicidal Activity of the Essential Oil of <i>Zingiber collinsii</i> against <i>Aedes albopictus</i> and <i>Cule</i><i>x quinquefasciatus</i>

“…The constituents of essential oils of Z. collinsii leaf are being reported for the first time. The abundance of α-pinene and β-pinene in the rhizome oil was in agreement with a previous report on the same part 11 . As usual, ubiquitous terpenoids were identified in both essential oils, consistent with most data obtained for the essential of Zingiber genus analysed from Vietnam and other parts of the world.…”

“…A chemical investigation of the rhizomes of Z. collinsii resulted in the isolation and identification of zerumbone, acoumarin scopoletin , quercetin, rutin, 5-hydroxymethyl furfural, bisdemethoxycurcumin and demethoxycurcumin 10 . The monoterpene hydrocarbons, α-pinene 50.2 , β-pinene 23.6 and limonene 5.3 were reported previously as the main constituents of the rhizome oil 11 . Till moment the authors are not aware of any report describing the biological activity of Z. collinsii essential oils.…”

Primary study on the components and main physico-chemical as well as biological properties of the oil of Alpinia galanga (L.) Wild in Phu Tho-Vietnam

“…The used injector temperature was 230°C. The MS conditions were as follows: Ionization voltage was 70 eV, transfer temperature was 250°C, the carrier gas was helium used at a flow rate of 0.5 ml/min, and the split ratio of the injector was 1:5 (Loi et al, 2015;Charles et al, 1992;Thang and Loi, 2016;Chau et al, 2014). The MS fragmentation patterns were compared with known patterns of other oils and with those in the literature by using Wiley (Wiley 9 th Version), NIST 08Libraries (on ChemStation HP).…”
