Antioxidative effect of extracts from Erodium cicutarium L.
Extracts from Erodium cicutarium L. (EC) and some standard substances present in EC extracts were tested for their antioxidative properties during Fe(2+)-induced triglyceride oxidation. Hydrophobic fractions such as petroleum ether (PEE), benzene (BE) and chloroform I (ChE I) extracts as well as hydrophilic fractions i.e. water (WE) and ethyl acetate (EAE) showed an antioxidative effect. Among ...
متن کاملHemp (Cannabis sativa L.) and abortion.
The correspondence of Zias et al. (1993), related the finding of carbonized matter containing tetrahydrocannabinol (THC), the primary psychoactive component of marijuana, in the abdomen of an adolescent girl who apparently died in childbirth around 400 AD. The researchers’s hypothesis was that Cannabis was administered to women in child birth to relieve pains and increase uterine contractions b...
متن کامل1 8 Ju l 2 01 3 Far Field measurement in the focal plane of a lens : a cautionary note
We study theoretically the accuracy of the method based on the Fourier property of lenses that is commonly used for the far field measurement . We consider a simple optical setup in which the far-field intensity pattern of a light beam passing through a Kerr medium is recorded by a CCD camera located in the back focal plane of a thin lens. Using Fresnel diffraction formula and numerical computa...
متن کاملSelf-burial Mechanism of Erodium cicutarium and Its Potential Application for Subsurface Exploration
Erodium cicutarium L. plants disperse their seeds by a combination of two dispersal strategies: explosive dispersal, and self-burial dispersal. As the fruits dry, the stresses developed in the structure cause the sudden separation of the seeds that fly away from the plant. Then, once on the ground, the seeds respond to variations in the external humidity : their dispersal unit, is helical when ...
متن کاملTissue-Specific Response to Experimental Demethylation at Seed Germination in the Non-Model Herb Erodium cicutarium
Experimental alteration of DNA methylation is a suitable tool to infer the relationship between phenotypic and epigenetic variation in plants. A detailed analysis of the genome-wide effect of demethylating agents, such as 5-azacytidine (5azaC), and zebularine is only available for the model species Arabidopsis thaliana, which suggests that 5azaC may have a slightly larger effect. In this study,...
