Essential oil constituents of aerial parts of Artemisia scoparia Waldst. & Kit.

Abstract

Hydrodistilled oil obtained from the aerial parts of Artemisia scoparia Waldst. & Kit. was analysed by capillary GC and GC-MS. The volatile oil of the 10-15 cm high herb was composed mainly of eight monoterpenes (ca. 68.5%), and the predominant constituents were β-myrcene (24.4%), γ-terpinene (18.3%), neral (12.5%) and cis-p-mentha-2-en-1-ol (5.1%). Among seven sesquiterpenes (6.9%) present in the oil, the prominent one was β-caryophyllene (3.4%). p-Cymene (17.4%) and p-cymene-8-ol were the characterized aromatic compounds in the volatile oil. Three aliphatic constituents, identified as n-octane, n-heptadecane and n-eicosane, occurred in trace ExperimentalFresh aerial parts of A. scoparia were collected from the cultivated species grown in the Herbal garden of Jamia Hamdard, New Delhi, India. The plant material was identified and authenticated by Dr. M. P. Sharma, Department of Botany, Jamia Hamdard, New Delhi, India. A voucher specimen (No. DBT-01-03) is deposited in the herbarium of the Department of Pharmacognosy and Phytochemistry, Jamia Hamdard. Isolation of OilThe air-dried plant material was hydrodistilled in an all-glass apparatus according to the method recommended by the British Pharmacopoeia, 1988. The pale yellow oil was dried over anhydrous sodium sulphate and stored at 4°C in the dark. The yield was 0.65% based on the dry weight of sample. GC AnalysisAnalytical GC with FID detector was carried out on a Varian 3300 gas chromatograph fitted with Silicone DB-1 capillary column (30 m × 0.25 mm i.d., film thickness 0.25 µm). The carrier gas was helium at a flow rate of

Antifungal Activity of Essential Oils from Three Artemisia Species against Colletotrichum gloeosporioides of Mango

“…β-myrcene (30.2%), β-cymene (12.8%), and (+)-limonene (12.4%) were the main monoterpenes of the fresh leaves of A. scoparia , collected during the last week of June in northern India (Chandigarh) [ 57 ]. Moreover, the major components from the volatile oils were β-myrcene (24.4%), β-terpinene (18.3%), and neral (12.5%) in northern India (New Delhi) [ 58 ]. Essential oils have very complex ingredients, containing 20–60 components in different concentrations [ 59 , 60 ]; previous studies have been conducted on which ingredients work.…”

The First Report on Chemical Composition and Antimicrobial Activity of Artemisia scoparia Waldst. et Kit. Extracts

“…Kapoor et al determined that the major components of A. scoparia oil from India were β-myrcene, γ-terpinene, pcymene, and neral. 28 Hydrocarbon monoterpenoids were the predominant class of compounds. In A. scoparia volatiles from India monoterpenoids amounted to about half of the total oil content and γ-terpinene and eugenol were the most abundant constituents.…”
