The Australian desert shrubEremophila (myoporaceae): Mmedicinal, cultural, horticultural and phytochemical uses

Identification of antibacterial constituents from the indigenous Australian medicinal plant Eremophila duttonii F. Muell. (Myoporaceae)

“…The endemic Australian genus Eremophila is particularly well represented in the medical ethno-botanical literature, ranking alongside the genus Acacia as one of the most widely and intensively employed in traditional medicine. The genus has also attracted a fair amount of phytochemical interest owing to its characteristic accumulation of copious quantities of resinous leaf exudates (in some cases up to 20% of total leaf mass) and by the ability to elaborate structurally and stereochemically unusual terpenoids, unique within the plant kingdom (Richmond and Ghisalberti, 1994). Ghisalberti (1994a) has provided a comprehensive review of the ethno-pharmacology and phytochemistry of this genus and the family Myoporaceae as a whole.…”

“…The epimer, (+)-ngaione (ipomeamarone), is an antifungal phytoalexin found in the sweet potato, Ipomoea batatas L. Lam. (Convulvulaceae) under challenge from pathogenic fungi and other noxious stimuli (Richmond and Ghisalberti, 1994;Ghisalberti, 1994a). Both (−)-ngaione and (−)-3,4-dehydrongaione are known to be renaland hepato-toxic, having been demonstrated to be responsible for stock poisoning by grazing of Myoporum sp.…”

The genus Eremophila (Scrophulariaceae): an ethnobotanical, biological and phytochemical review

“…Four concentrations of extract were prepared: 16, 32, 64 and 128 mg/ml. The 128 mg/ml dose of the [14,21,22] E. cuneifolia Leaves Relieving common cold and headache [14] E. dalyana Leaves Treatment of colds and other chest ailments As a body wash for scabies [6] E. duttonii Leaves Treatment of minor dermal wounds and infected lesions derived from infestation by the scabies mites Treatments of ophthalmic and oto-nasopharyngeal complaints Insect repelling properties [21] E. fraseri Leaves To alleviate colds and To cure toothache and rheumatism As a sealant and an adhesive [19] E. freelingii Stems and leaves Against cough, common cold, and fever Against chest and body pain To alleviate diarrhoea [25,26] E. gilesii Leaves Treatment of colds, headache, chest pain As antibacterial agent for sores [3]…”

“…[2] The name Eremophila is derived from the Greek words Eremos meaning 'desert' and phileo 'love' , indicating that most of these species are adapted to live under the harsh conditions of the deserts and semi-arid places. [3] Eremophila comprises approximately 214 species, usually with alternate, shortly petiolate and lanceolate leaves with entire or dentate margin and acute apex. Many leaves are grey and hairy, and are thus protected against intensive light.…”

Antibacterial Performance of Terpenoids from the Australian Plant Eremophila lucida

“…Phytochemical investigations of species in the genus Eremophila have led to the isolation and identification of over 200 secondary compounds from several classes, with particularly rich diversity in sesqui- and diterpenoids [2]. This diversity of secondary compounds and the traditional use of some species has highlighted the pharmacological potential of this genus [3,4,5]. In more recent years biological activities have been found for various Eremophila extracts and isolated secondary compounds, including anti-inflammatory, antimicrobial and cytotoxic activities, and cardioactive effects [2,6,7,8,9,10,11].…”
