Volatile Constituents of Large Cardamom (Amomum subulatum Roxb.)

Abstract

The steam-distilled volatile oil of the large cardamom (Amomum subulatum Roxb.), grown in Sikkim, India, was analysed by GC-MS. It consists of monoterpenic hydrocarbons (16.3%), oxygenated rnonoterpenes (75.2%) and sesquiterpenes (6.3%). Its major constituents are l,&cineole (61.3%), a-terpineol, a-and P-pinene and alloaromadendrene. Twenty-five compounds are reported for the first time.KEY WORDS large cardamom; Amomum subulatum Roxb.; Zingiberaceae; steam-volatile constituents; mono-and sesquiterpenes; GC-MS

Amomum tsao-ko —Chinese Black Cardamom: Detailed Oil Composition and Comparison With Two Other Cardamom Species

“…This is well in line with some previously published analyses. 18,20,31,33-35,39,45 However, one previous analysis reported very high levels of limonene together with other major compounds which were not present in our analysis. 25…”

“…This is well in line with some previously published analyses. 18,20,31,[33][34][35]39,45 However, one previous analysis reported very high levels of limonene together with other major compounds which were not present in our analysis. 25 Both oils contained very characteristic indane (=2,3-dihydro-1H-indene) derivatives: 4-indanecarbaldehyde (1) and 5-indanecarbaldehyde (2) and the respective dihydroindane compounds trans-and cis-2,3,3A,7A-tetrahydro-1H-indene-4-carbaldehyde (3/4) (Figure 1).…”

Identification and Sequencing of β-Myrcene Catabolism Genes from Pseudomonas sp. Strain M1

“…This compound was identified by the comparison of its MS spectrum with that of the authentic chemically synthesized compound. Although (E)and/or (Z)-myrcen-8-ols have already been found in insect pheromones and essential oils and recognized by their mass spectra (5,26,30,31), we failed to find any reported mass spectral data in the literature. To our knowledge, this is the first report of the mass spectrum of 2-methyl-6-methylen-2,7octadien-1-ol.…”

One-Step Green Synthesis of Gold Nanoparticles Using Black Cardamom and Effect of pH on Its Synthesis

“…There are few reports available on pharmaceutical composition of black cardamom which indicate that out of 40 identified compounds of black cardamom, 1,8-cineole (65 %), β-Pinene (0.85 %), and α-Terpineol (7.92 %) are the main constituents [ 45 ].…”
