“…Table 1 indicates the chemical constituents present in the oil, their percentages as well as retention indices on HP-5MS column. Monoterpene hydrocarbons (68.0%) and oxygenated monoterpene (14.9%) represent the main classes of compounds The chemical compositions of essential oils from some other Alpinia plant grown in Vietnam have been reported [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21] as shown in Table 2. A comparative analysis of the compositional patterns of essential oils of A. pinnanensis with other Alpinia species grown in Vietnam revealed a marked variation in their chemical constituents.…”

“…For example, while high contents of α-pinene and β-pinene were reported in the essential oils of the leaves of A. malaccensis [8] camphor, α-pinene and βagarofuran makes up the abundant compounds of A. polyantha [9]. In addition, 1,8-cineole was the prominent compound in the rhizome oil of A. henryi [10]. The quantitatively significant compounds of the flower oil of A. chinensis were caryophyllene oxide and β-bisabolene [11].…”

“…Although several Alpinia plants have been studied for their biological [2][3][4] and non-volatile [5,6] components, there is lack of information on the volatile and nonvolatile chemical constituents and biological activities of the studied plant. This arouses our interest in this research into the volatile compositions of this relatively unexploited flora of Vietnam. There are literature reports on the essential oil constituents from Alpinia plants collected from Vietnam [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21]. Although monoterpenes and sesquiterpenes compound constituted the bulk of the oil samples, there are marked variations in their chemical constituents.…”

The chemical composition of volatiles from the fruits of Alpinia menghaiensis S. Q. Tong & Y. M. Xia (Zingiberaceae) has been studied. The essential oils were obtained by hydrodistillation in a Clevenger-type apparatus and analyzed by gas chromatography (GC-FID) and gas chromatography coupled with mass spectrometry (GC-MS). The components of the essential oils were identified by comparison of their mass spectra (MS) data and linear retention indices (LRI) with literature data. The essential oil content was 0.32% (v/w), calculated on a dry weight basis.

Objective: Alpinia is a big genus of flowering plants in the family Zingiberaceae. The plants of this genus are generally aromatic due to their essential oils. The current study aims to identify chemical compositions in the rhizome and leaf oils of Alpinia vietnamica H.Đ. Trần, Luu & Škorničk. Methods: Essential oils of A vietnamica rhizomes and leaves obtained by hydrodistillation were investigated by the gas chromatography–flame ionization detection/mass spectrometry (GC–FID/MS) analysis. A vietnamica essential oils have been subjected to cytotoxic and α-glucosidase inhibitory assays. The protein interactions of the major compounds were viewed by molecular docking study. Results: In general, monoterpene hydrocarbons (60.4%-62.5%) and their oxygenated derivatives (18.1%-29.0%) were the main chemical classes of the rhizome and leaf oils. In the meantime, 1,8-cineole (25.7%-29.0%), β-pinene (12.8%-21.3%), geraniol (9.0%-15.2%), and α-pinene (6.1%-7.5%) can be seen as the main compounds. A vietnamica essential oils showed cytotoxicity toward four cancer cell lines KB, Hep-G2, Lu-1, and MCF-7 with IC50 values of 82.39 to 254.1 µg/mL. Significantly, the leaf oil (IC50 115.18 µg/mL) was better than the standard compound acarbose (IC50 156.68 µg/mL) in the α-glucosidase inhibitory assay. The results of molecular docking simulation suggested that 1,8-cineole, geraniol, α-pinene, and β-pinene could generate a similar inhibition (binding affinities) with acarbose, and the hydrogen and hydrophobic interactions played contributory roles in the binding to α-glucosidase enzyme. Conclusion: Further phytochemical investigations on this species, especially chromatographic separations to isolate bioactive metabolites, are needed. As well, pharmacological experiments are welcome since the current study is the first result.
