Variation in the composition of the essential oil of Valeriana officinalis L. roots from Estonia
The volatile constituents from roots of Valeriana officinalis L. were investigated using GC and GC/MS methods. Valerianae radix samples were obtained from retail pharmacies or cultivated in Estonia. The roots of five V. officinalis samples yielded 0.28–1.16% essential oil in the cut drug, which usually corresponded (four samples) to the European Pharmacopeia standard (0.3%). The basic oil compo...
متن کاملValeriana officinalis attenuates the rotenone-induced toxicity in Drosophila melanogaster.
In this study, we investigated the potential protective effects of Valeriana officinalis (V. officinalis) against the toxicity induced by rotenone in Drosophila melanogaster (D. melanogaster). Adult wild-type flies were concomitantly exposed to rotenone (500 μM) and V. officinalis aqueous extract (10mg/mL) in the food during 7 days. Rotenone-fed flies had a worse performance in the negative geo...
متن کاملComplex Variation in the Brain Arteries in Tehran
Variations in the cerebral arterial circle (CAC) correlate with incidence of some cerebrovascular diseases and must be considered during surgical operations (1, 2). It also seems that different distribution of variations of the CAC is related to the race. This issue may partially explain the different incidences of some of the cerebrovascular diseases in different ethnic or racial groups (3-5)....
متن کاملFlower size variation in Rosmarinus officinalis: individuals, populations and habitats.
BACKGROUND AND AIMS Flowers are relatively invariant organs within species, but quantitative variation often exists among conspecifics. These variations represent the raw material that natural selection can magnify, eventually resulting in morphological divergence and diversification. This paper investigates floral variability in Rosmarinus officinalis, a Mediterranean shrub. METHODS Nine pop...
متن کاملthe influence of corpus luteum on follicular fluid composition from different size follicles and their relationship to serum concentrations in sanjabi ewes
the aim of the present study was to determine the in?uence of presence or absence of corpus luteum (cl) on hormonal and metabolites composition of follicular ?uid (ff) harvested from different sized follicles and its relationship with blood serum concentrations in sanjabi ewes. ovaries and blood samples were collected from 60 clinically healthy adult ewes (sanjabi breed) 1–3 years of age in dio...
