Volatile constituents of Elsholtzia fruiticosa (D. Don) Rehder were studied by two different extraction techniques, supercritical fluid extraction (SFE) and hydrodistillation (HD), and the results were compared with head space analysis (HS). Thirty-five constituents were identified in both the SFE and HD oils and fourteen in the HS, accounting for 94.2%, 97.7% and 96.9% of the total identifications, respectively. A distinctive feature of the results was the very high content of non-terpenes (59.8%) in the HS, the high content of oxygenated monoterpenes (41.1%) in the HD oil and the high content of sesquiterpene hydrocarbons (21.8%) in the SFE oil. Monoterpene hydrocarbons were represented in HS (13.6%), HD (19.4%) and SFE (4.3%). In SFE sesquiterpene hydrocarbons formed 21.8% of the total, as compared to 6.6% in the HD and 1.1% in the HS Oxygenated sesquiterpenes represented 3.0% in SFE, 0.8% in HD and were absent in HS. Diterpenes were only present in the SFE oil (3.4%). Non-terpenes were represented by 24.5% in the SFE oil and 29.8% in the HD oil.

“…Among them, α-pinene, β-pinene, acetophenone, caryophylene oxide, carvacrol, benzaldehyde, β-caryophyllene, 1,8-cineole, α-phellandrene, and α-terpineol widely exist. Especially, α-pinene and β-pinene are most significant two, which were detected and identified in 15 species in the genus [45-66]. Acetophenone, caryophylene oxide, carvacrol, benzaldehyde, β-caryophyllene, α-phellandrene, and α-terpineol are also major examples.…”

Plants of the genus Elsholtzia (Lamiaceae) have a long history of medicinal use in folk. The phytochemical investigations revealed the presence of flavonoids, phenylpropanoids, terpenoids, and other compounds. Abundant volatile components are also identified. Pure compounds, volatile constituents and crude extracts from the genus exhibited a wide spectrum of in vitro and in vivo pharmacological activities. The aims of this review hopefully provide comprehensive information on the distribution, phytochemistry, volatile components, and pharmacological research of Elsholtzia for exploring the potential and advance researches.

“…2,4-Dithiapentane (representing 11.35% of their compounds) was also reported to be the major component of the oil. It is apparent that the major components of the essential oils of the rhizomes of T. violacea do not include the usual monoterpenoids and sesqiterpenoids associated with essential oils reported in literature (Tariku et al, 2011;Ahmad et al, 2006;Dos Santos et al, 2001;Ahmad et al, 1988). The oil of T. violacea is rather rich in sulfur-containing compounds that are similar to those found in Allium sativa (garlic) (Martinez-Velazquez et al, 2011; El-meleigy et al, 2010; Dieumou et al, 2009;Kimbaris et al, 2008).…”

Tulbaghia violacea Harv L.F. is one of the many medicinal plants used by Zulu traditional healers to treat respiratory tract diseases. Essential oil extracted from the rhizomes of T. violacea was evaluated for its chemical composition, antioxidant and antibacterial activities. The gas chromatography/mass spectrometry (GC/MS) analysis of the oils revealed the main constituents of the essential oils of T. violacea to be 2,4-dithiapentane (51.04%), ρ-xylene (20.59%), chloromethylmethyl sulfide (8.69%), σxylene (7.38%), thiodiglycol (6.43%) and ρ-xylol (5.88%). While the oil showed weak antioxidant activity, the antimicrobial activity of the essential oil carried out on both Gram positive and negative bacteria (using the agar disk diffusion method) showed that the oil of T. violacea was effective against 8 of the 16 microorganisms tested, with MIC values ranging from 2.5 to 5.0 mg/ml. The oil had low (1218 and 1641 µg/ml) cytotoxicity levels against HEK293 and HepG2 cell lines, respectively. It is apparent that the bioactivity of the essential oil of T. violacea contributes to the use of this plant in folk medicine.
