The traditional therapeutic indications for the use of Ajuga reptans (Labiatae) have been investigated. The H2O-soluble part of a crude and partially purified MeOH extract and two isolated iridoids (8-O-acetylharpagide and harpagide), were tested for a biological activity on isolated smooth muscle
We have identified a novel nonsteroidal ecdysteroid agonist. This compound was isolated from a methanol extract of Ajuga reptans L. (Lamiaceae) and the structure was identified by spectroscopic methods as 8-O-acetylharpagide. We have characterised this compound as an ecdysteroid agonist in a
We have reinvestigated the activity of 8-O-acetylharpagide, an iridoid glucoside, as an ecdysteroid agonist. Elbrecht et al. (Insect Biochem. Mol. Biol. 26 (1996) 519) isolated a preparation of this compound from Ajuga reptans L. and ascribed ecdysteroid agonist activity on the basis of the
8-O-acetylharpagide and harpagide are two kinds of effective component of Ajuga decumbens extract. A sensitive LC-MS/MS method has been established for pharmacokinetics of 8-O-acetylharpagide and harpagide in beagle dog after oral administration of from A. decumbens extract. Female beagle dogs

From the aerial parts of Ajuga salicifolia (L.) Schreber, a new ionone glycoside (3beta-hydroxy-7,8-dihydro-4-oxo-beta-ionol-9-O-beta-D-glucopyranoside) was isolated, along with the known compounds, corchoionoside C, 8-O-acetylmioporoside, ajugol, harpagide, 8-O-acetylharpagide, lavandulifolioside
We report the first analysis in absolute, and in particular, concerning the phytochemical pattern, about an endemic Italian species, Ajuga tenorei C. Presl. The analysis, performed by means of techniques such as Column Chromatography and NMR spectroscopy and Mass spectrometry, led to the isolation
Ajuga chamaepitys (L.) Schreb, well-known as Camaepitium or Ground Pine, is an annual herb typical of the Mediterranean area accounting several uses in the traditional medicine. In this work we have, analyzed the plant iridoid fraction together with the essential oil composition and study of the
Ajuga bracteosa Wall ex. Benth. (Lamiaceae) has been reported to possess many biological activities including antibacterial, antifungal, antispasmodic and antioxidant activity but there is no report as such on its mutagenic and/or anti-mutagenic activity. The aim of the present study was to isolate
Treatment and control of malaria have become more difficult with the spread of drug-resistant parasites and insecticide-resistant mosquito vectors. In the search for new antimalarial drugs, ethnopharmacological sources should merit more attention. Establishing the safety of traditional herbal
Context Some Ajuga L. (Lamiaceae) species are traditionally used for the treatment of malaria, as well as fever, which is a common symptom of many parasitic diseases. Objective In the continuation of our studies on the identification of antiprotozoal secondary metabolites of Turkish Lamiaceae
Ajuga remota is the most frequently used medicinal herb for malaria treatment in Kenya. Its two known isolates ajugarin-1 (1) and ergosterol-5,8-endoperoxide (3) and a new isolate 8-O-acetylharpagide (2) were evaluated for their in vitro antiplasmodial activity. Ajugarin-1 was moderately active,
