To investigate the potential for the utilization of cotton stalk, ammonia hydrothermal treatment was applied to fractionate the samples into aqueous ammonia-soluble and ammonia-insoluble portions. The ammonia-soluble portion was purified to yield lignin fractions. The lignin fractions obtained were characterized by wet chemistry (carbohydrate analysis) and spectroscopy methods (FT-IR, 13C and 1...

Benign Prostatic Hyperplasia (BPH) affects, worldwide, 50% of 60-year-old men. The Peruvian plant red maca (Lepidium meyenii) inhibits BPH in rodents. This study aimed to determine the effects of methanolic red maca extract and its n-butanol and aqueous fractions on expression of androgen and oestrogen receptors in rats with testosterone enanthate-induced BPH. Thirty-six rats in six groups were...

Rural dwellers in Nigeria often resort to herbal remedy and dietary control in the treatment of diabetes mellitus (DM). This work was undertaken to provide the rationale for the use of the leaves of Gogronema latifolium as a traditional antidiabetic agent. Methanol extract (ME) of the leaves of G. latifolium was prepared by soxhlet extraction while the aqueous extract (AE) was prepared by cold ...

Purpose: To evaluate the amino acid, antioxidant and ionic profiles of Carpolobia lutea leaf (Polygalaceae) extract (CLL). Methods: The powdered leaf was macerated and subjected to gradient solvent extraction with nhexane, chloroform, ethyl acetate and ethanol for 72 h to obtain their respective fractions. Amino acid analysis was by cation-exchange chromatography using automated amino acid anal...

With the procedure which is described, brain tissue is separated into six fractions, the sum of whose weights equals the dry weight of the tissue. Three of these primary fractions are further separated into subfractions. Recovery is quantitative at each step. The procedure, as applied to rat brain, gave consistent results; duplicate analyses of the two halves of brains, divided as equally as po...

EARLY analyses of the proteins of the normal aqueous humour by Franceschetti and Wieland (1928), and later by Kronfeld (1941) and Kronfeld and others (1941), have shown a content of 10 to 20 mg. per cent. Any functional significance this protein may have is unknown. However, the human lens contains 30-40 p' r cent. protein, the fractions of which have been determined by several authors (Cagianu...

BACKGROUND Diabetes is a serious metabolic disorder affecting the metabolism of carbohydrate, protein and fat. A number of studies have shown that diabetes mellitus is associated with oxidative stress, leading to an increased production of reactive oxygen species. Ficus deltoidea is traditionally used in Malaysia for regulating blood sugar, blood pressure and cholesterol levels. The use of F. d...

A study of the chemical composition essential oil obtained from aerial parts Salvia glutinosa L., growing in Georgia, was carried out. The percentage dominant components determined by integration, component are caryophyllene oxide (11.43 %), spathulenol (5.93 humulene (4.5 %). From terpene compounds oxygenated sesquiterpenes dominants. content phenolic  using Folin-Ciocalteu reagent aqueou...

Despite the traditional use of Solidago canadensis L. (Asteraceae) as a diuretic drug, there is a scarcity in scientific data concerning the activity of its different extracts and fractions as well as the class of constituents responsible for this diuretic action. A comparative study was carried out for the diuretic activities of the different standardized extracts and fractions of the...
