The genus Montenegrina is revised on the basis of material available at the Hungarian Natural History Museum (Budapest), Naturhistorisches Museum Wien (Vienna), and the Naturmuseum Senckenberg (Frankfurt am Main), as well as newly discovered populations. The following new taxa are described: Montenegrina haringae sp. n., Montenegrina lillae sp. n., Montenegrina prokletiana sp. n., Montenegrina ...

The structure of a new diterpene, C30H46O11, with antibacterial activity against Pseudomonas aeruginose and Escherichia coli, isolated from the fresh whole plants of Ajuga lupulina (Labiatae) was established to be 2 beta-hydroxy-2-methylbutanoyl-3 alpha-lupulin (3-deoxy-14,15-dihydro-2-hydroxy-15-methoxycaryoptinol 2-methylbutanoate), by means of X-ray crystallographic analysis. The present stu...

We investigated the in vivo activity of crude water extracts of Ajuga remota Benth (Labiatae) against Plasmodium berghei in mice using plants harvested from two areas in Kenya where the plant is commonly used to treat malaria. The extract was tested using a 4-day test at a dose of 30 mg/kg/day (equivalent to 0.2 ml solution per mouse). Wet leaf extract was the most effective with 90.4% suppress...

The crop species Brassica rapa L. has significant economic importance around the world. However, the global distribution and complex evolutionary history of the species has made investigating its genetic population structure difficult. Crop domestication and improvement has resulted in extreme phenotypic diversity and subspecies that are used for oilseed, food for human consumption, and fodder ...

Background and objectives: To date, thousands of secondary metabolites have been isolated from plants and microorganisms and there is an unprecedented attention towards potential biomedical applications of natural compounds. In this study, cytotoxic properties of methanol extracts of Stachys obtusicrena, Aristolochia olivieri, Linum album, Dionysia sawyeri, Ajuga chamaecist...

Background & Aim: The aim of this research is investigation and familiarity with the important herbal drugs that have used for traditional curing of animal diseases in different areas of Kerman province, Iran. From a long time ago native farmers and tribes of different regions used the available natural herbs which existed in those regions to cure animal diseases in different areas of Kerman pr...

The volatile oil content and composition of the aerial parts of Ajuga orientalis L. (Lamiaceae) grown in northern parts of Iran have been analyzed by GC/MS. Thirty compounds were identified, representing 97.9% of the total oil. The main compounds were germacrene-D (24.2%), beta-cubebene (18.3%), beta-caryophyllene (16.9%) and alpha-cubebene (5.3%).

Stabilities of anthocyanins from Concord grapes, red cabbage, tradescantia and ajuga were studied. RP-HPLC analysis was used to characterize individual anthocyanins and spectrophotometric analysis for all pigments. Anthocyanins from tradescantia were much more stable than the other extracts. Such increased stability was attributed to its intrinsic nature.
