Relatively few animal species extract seeds from closed conifer cones because of the forces required to spread apart or penetrate the woody scales. Those species that forage on seeds in closed cones tend to forage selectively, and therefore act as selective agents on cone structure. However, little is known about the foraging preferences and thus phenotypic selection that is exerted on conifers...

The present article describes the chemical characteristics such as pH of aqueous extract, fluorescence, aqueous and alcoholic extractives, lignans and TLC profile of aqueous extract of Bhuiavli (Phyllanthus niruri).

AIM To determine the effect of two different extracts of red maca in male rats. METHODS Prostatic hyperplasia was induced in male rats with testosterone enanthate (TE). The study comprised six groups: one control group (group 1), one group treated with TE (group 2), two groups treated with TE and aqueous extract of red maca (groups 3 and 4), one group treated with hydroalcoholic extract of re...

BACKGROUND As part of the indigenous folk medicine in Japan, aqueous extracts of pine cones have been used for over a century to treat cancer and other illnesses and references to their use can be found in ancient Greek literature. However, the mechanisms by which such extracts work are largely unknown. MATERIALS AND METHODS Murine bone marrow (BM)-derived dendritic cells (DCs) and human mono...

BACKGROUND & OBJECTIVE Aqueous and organic solvent extracts of plants/plant parts were effective in killing the mosquito larvae. Comparative efficacy of the aqueous and hexane extracts of dried fruit of Solanum nigrum was tested against five laboratory colonized strains of mosquito species, namely Anopheles culicifacies species A, An. culicifacies species C, An. stephensi, Culex quinquefasciatu...

BACKGROUND Extracts of plants have been considered as sources of natural antioxidant agents. In this study, we aimed to explore the antioxidant capacity of the aqueous root extract of Asparagus cochinchinensis (Lour.) Merr. METHODS Using vitamin C (Vc) as a positive control, we analyzed the aqueous root extract of A. cochinchinensis free radical scavenging ability in vitro. We also establishe...

Cetraria islandica (Iceland moss) has been used for centuries in folk medicine in many countries against a number of conditions, including inflammatory conditions, mainly as an aqueous extract. C. islandica contains many compounds, such as polysaccharides and secondary metabolites, some of which have established biological activity. However, very little is known about their effect on the immune...

The present study aimed to assess the protective effects of aqueous extract from Morinda officinalis F. C. How on microwave-induced reproductive impairment in male rats. Microwave exposure injury was induced by exposure of 900 MHz microwaves at 218 μm/cm(2)radiation densities, 24 hours/day for 10 days. Male Sprague-Dawley rats were randomized to: normal control, microwave exposure model, or wat...

Thin layer chromatography of aqueous extract of whole Cheilanthesfarinosa fern indicated the presence of ptaquiloside or ptaquiloside like compound, coinciding Rf values with that of Pterosin B standard. HPLC analysis revealed the presence of 26.3 mg/kg ptaquiloside. In vitro studies of the aqueous extract on lymphocyte culture revealed a correlation between stimulative indices and concentratio...
