due to the growing trend of rangelands degradation, study effects of different harvesting intensities on species in order to gain a more fundamental utilization of ranglands can be effective for reclamation and improvement. the purpose of this research was to study effects of different harvesting intensities on key species ajuga chamaecistus.this species has a forage value in the study area. in...

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 and leonosides A and B. This is the first report of the occurrence of ionone glycosides and 8-O-ac...

In the present work, a comprehensive study was made on the analysis of chemical composition of essential oil and antibacterial activity from the leaves of Ajuga bracteosa. The essential oil was extracted by Cleavenger type apparatus and analyzed by GC-MS. The main components present in the essential oil of leaves are Limonene, α-humulene, β-Myrcene, Elemol, Camphene, βCaryophellene, α-phellendr...

Background: Ajuga species are anthelmintic, diuretic, antifungal, and antimycobacterial agents.Lamiaceae members Ajuga postii Briq. and Ajuga relicta P.H.Davis are local endemic species of Turkey. Aim: To give information about the total phenolic contents and antioxidant activities of the species. Methods: The total phenolic contents of the extracts have been quantified with Folin Ciocalteu col...

We studied the efficacy of water-soluble extracts from four Ajuga spp on the post-embryonic development of two exopterygota (sucking insect) species. To allow comparison between different Ajuga species, results are expressed in terms of quantity of plant extracted per litre of test solution. Crude methanolic extracts of all Ajuga plants tested, with the exception of A genevensis, showed conside...

In chloroplasts, several water-soluble carbohydrates have been suggested to act as stress protectants. The trisaccharide raffinose (alpha-1,6-galactosyl sucrose) is such a carbohydrate but has received little attention. We here demonstrate by compartmentation analysis of leaf mesophyll protoplasts that raffinose is clearly (to about 20%) present in chloroplasts of cold-treated common bugle (Aju...

The objective of the present study is to determine the bioefficacy of different crude extracts of Ajuga remota against anopheline and culicine larvae. Larval susceptibility of crude carbon-tetrachloride, methanol and petroleum-ether extracts of Ajuga remota leaves was observed against the malaria vector, Anopheles stephensi and the filariasis vector, Culex quinquefasciatus. Among the extracts t...

Feeding synthetic [2beta-2H]- and [2alpha-2H]-cholesterols to the hairy roots of Ajuga reptans var. atropurpurea and 2H-NMR analysis of the biosynthesized 20-hydroxyecdysone revealed that hydroxylation at C-2 proceeds with retention of configuration. Feeding [2alpha,3alpha-2H2]cholesterol followed by 2H-NMR analysis of the 2,3,22-triacetate of the resulting 20-hydroxyecdysone ruled out a mechan...
