Background: Fritillaria imperialis is an endangered species with pharmaceutical alkaloids that can be effective in reducing blood pressure and reducing cardiac palpitations.   Objective: Comparison of head space solid phase microextraction (HS-SPME) and hydro-distillation (HD) techniques in determination of essential oils in Fritillaria imperialis Methods: Quality and quantity determination o...

in this study, the quantity and quality of essential oil (eo) of chamomile cv. ‘bodegold’, moldavian dragonhead cv. ‘szk1’ and fennel cv. ‘soroksari’ were evaluated in shahrekord climate condition in spring 2014, shahrekord university. chamomile’ flowers and dragonhead’ herb were harvested at full flowering stage. fennel’ fruits were harvested at waxy and full-matured stages. the eo content of ...

Essential oil yield and composition in aromatic crops might be affected by genetic, agronomical environmental factors but till date there is no clear information about the harvesting time distillation for higher essential content without affecting quality. The current study was carried out to evaluate of chamomile flowers herb with part at three different times (6 A.M., 12 P.M. 6 P.M.) four tre...

This work describes the isolation and structural elucidation of compounds from the leaves of Myrcia tomentosa (Aubl.) DC. (goiaba-brava) and evaluates the antimicrobial activity of the crude extract, fractions and isolated compounds against bacteria and fungi. Column chromatography was used to fractionate and purify the extract of the M. tomentosa leaves and the chemical structures of the compo...

The chamomile drug (Chamomillae anthodium) is widely known and has been used as a medicine for ages. Today, the officially registered in European Pharmacopoeia. Despite economic importance of Matricaria recutita L., little about extent nature essential oil variability composition this species Albania.

abstract in order to study the effect of sowing date and seeding rate on essential oil content and composition of chamomile (matricaria recutita l.) cv. presov, prepared from slovakia, an experiment was conducted. the experimental design was split-plot in the basic of randomized complete blocked design (rcbd) with three replications. main plots consisted of three sowing dates (6 nov, 5 mar, and...

the present study explores the chemical constitution and antioxidant activity of the essential oils of the aerial parts of artemisia dracunculus l. and the flower heads of matricaria chamomilla l. gc-ms analysis revealed the presence of (z)-anethole (51.72%), (z)-β-ocimene (8.32%), methyleugenol (8.06%), limonene (4.94%) and linalool (4.41%) in artemisia dracunculus and (e)-β-farnesene (24.19%)...

Multi-target strategies are directed toward targets that are unrelated (or distantly related) and can create opportunities to address different pathologies. The antidermatophytic activities of nine natural skin lighteners: α-bisabolol, kojic acid, β-arbutin, azelaic acid, hydroquinone, nicotinamide, glycine, glutathione and ascorbyl tetraisopalmitate, were evaluated, in comparison with the know...
