Salvia divinorum is a hallucinogenic herb that is internationally regulated. In this study, salvinorin A, the active compound in S. divinorum, was extracted from S. divinorum plant leaves using a 5-min extraction with dichloromethane. Four additional Salvia species (Salvia officinalis, Salvia guaranitica, Salvia splendens, and Salvia nemorosa) were extracted using this procedure, and all extrac...

This study was done to investigate the interaction effect of the mixture of each pair of traditional medicinal plants including: Sage (Salvia officinalis), Hawthorn (Crataegusoxyacantha), Walnut Leaf (Juglansregia L.), Red Cabbage (Brassica oleracea), and Yellow Sweet Clover (Melilotus officinalis) on the antioxidant activities and free radical scavenging by using DPPH (2, 2-diphenyl-1-picrylhy...

Ten phenolic compounds were isolated from a butanol fraction of sage extracts. Their structures were determined by spectral methods (NMR, MS, IR). Among them, a novel compound, 4-hydroxyacetophenone-4-O-â-D-apiofuranosyl-(1f6)-O-â-D-glucopyranoside, was identified. Two test systems, DPPH free radical scavenging activity and radical cation ABTS•+ scavenging activity, were used to evaluate their ...

We have tested acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) inhibitory activities of nineteen essential oils obtained from cultivated plants, namely one from Anethum graveolens L. (organic fertilizer), two from Foeniculum vulgare Mill. collected at fully-mature and flowering stages (organic fertilizer), two from Melissa officinalis L. (cultivated using organic and chemical ferti...

background: salvia limbata is an aromatic herbaceous plant and grows widely in iran turkey and afghanistan. in the previous study, six flavones together with rosmarinic acid were isolated from the ethyl acetate and methanol extracts of s. limbata. in this report, we focused on the isolation and identification of the glycosylated sterols and the main accumulated amino acid of the species s. limb...

Four essential oils of Thyme (Thymus linearis), Lemon grass (Cymbopogon citratus), Rosemary (Rosmarinus officinalis), Mint (Mentha longifolia) and Formic Acid (65%) used at three concentrations (25, 50 and 100%) against Varroa destructor damaging honey bee Apis mellifera colonies in Honeybee Research Institute, National Agricultural Research Centre, Islamabad, Pakistan. The percentage of infest...

Unlike most other plant microsomal desaturases, the Delta6-fatty acid desaturase from borage (Borago officinalis) contains an N-terminal extension that shows homology to the small hemoprotein cytochrome (Cyt) b5. To determine if this domain serves as a functional electron donor for the Delta6-fatty acid desaturase, mutagenesis and functional analysis by expression in transgenic Arabidopsis was ...

AIM To determine the effect of a Calendula officinalis flower extract on lung metastasis by B16F-10 melanoma cells in C57BL/6 mice. MATERIALS AND METHODS Male mice were injected with B16F-10 melanoma cells through the tail vein and simultaneously treated with C.officinalis flower extract. Parameters studied were lung tumor nodule count, life span of animals, gamma glutamyl transpeptidase acti...
