Composition of the essential oil of flowers ofChloranthus spicatus (Thunb.) Makino

Abstract

The composition of the essential oil of the flowers of Chloranthus spicatus (Thunb.) Makino (Chloranthaceae) was investigated using capillary GC-GC/MS, preparative GC and NMR techniques. Forty-seven compounds were identified either by comparing their retention indices and mass spectra with a library of authentic samples established under identical experimental conditions or, by isolating the compounds and deriving their structures by one-and two-dimensional NMR investigations. Thus, four minor components, viz. chloranthalactone A (0.5%), isogermafurenolide (0.7%), eudesma-4(15),7(11),9-trien-12-olide (0.5%), and 7α α α α α-hydroxyeudesm-4-en-6-one (3.3%), were isolated for the first time as constituents of the essential oil of the flowers of C. spicatus and their structures established. The major components of the oil include (Z)-β β β β β-ocimene (6.3%), allo-aromadendrene (6.2%), sarisane (2-allyl-4,5-methylenedioxyanisol, 4.2%) and selina-4(15),7(11)-diene (6.4%).

A Review of Traditional Medicinal Plants from Kachin State, Northern Myanmar

“…According to Xu et al, the whole plant also contains chloramultilides B-D [67] and chlospicates A (27), B (28), C (29), D (30), and E (31) [68]. The flowers of C. spicatus have been reported to contain (E)-ocimene, 3,6-dimethyl-4,5-diethyl-3,5octadiene, 1-(1,4-dimethyl-3-cyclohexen-1-yl)-ethanone, 2,6dimethyl-2,4,6-octatriene, germacrene B, (Z)-ocimene, germacrene D, 3-carene, cadinol [69], chloranthalactone A, isogermafurenolide, eudesma-4 (15),7(11),9-trien-12-olide, 7α-hydroxyeudesm-4-en-6one, (Z)-β-ocimene, allo-aromadendrene, sarisane (2-allyl-4,5methylenedioxyanisol), selina-4(15),7(11)-diene [70], 4-hydroxy-βionone, methyl jasmonate, methyl epijasmonate [71], cis-methyl jasmonate, cis-β-ocimene and β-pinene [72]. The biological activities of the plant have not yet been determined; however, it appears that C. spicatus has a valuable potential for being submitted to pharmacological studies.…”

Germacrone: Occurrence, Synthesis, Chemical Transformations and Biological Properties

“…Germacrone (1) is found as part of the essential oils of different plants that are widely distributed throughout the world (for example, Bulgaria, Bolivia, Vietnam, Alaska, China, Serbia, India, North America, Nigeria, Formosa [13], Asarum caulescens [14], Pogostemon formosanus [15], Ledum palustre [16], Artemisia lagopus [17], Fluorensia oolepis [18], Fagara macrophylla [19], Magnolia grandiflora [20], Hyptis mutabilis [21], Commiphora myrrha [22], Acanthogorgia vagae [23], Lallemantia iberica [24], Chloranthus spicatus [25], Cyperus articulatus [26], and Metrosideros diffusa [27]. In addition, 1 is noteworthy for its abundance in different essential oils (with yields higher than 20% of the total oil [36], and Pogostemon formosanus (36.6%) [37].…”
