Triploid Populus tomentosa Carr. (Salicaceae) is a good alternative to meet the increasing need of the global pulp and paper industry. Meanwhile, the xylem of this species could be a useful bioresource to develop low molecular extractives with significant bioactive potential. In the present work, a phytochemical investigation on aqueous EtOH extractives of Triploid P. tomentosa xylem, by system...

BACKGROUND As the most common form of dementia, Alzheimer disease is characterized by progressive loss of memory and deterioration of cognitive functions. It is predicted that about 75.63 million people would suffer from dementia by 2030. Apart from conventional remedies, the application of herbal medicines is on the rise. There are numerous natural medicaments reported in the traditional manus...

Atrocapus lakoocha Roxb. or Ma-haad, is a tree in Moraceae family. The main stilbenoid in the heartwood of this plant, oxyresveratrol is an active substance that promotes strong tyrosinase inhibitory and antioxidative effects. In this study, thin layer chromatographic (TLC) – densitometric method was developed and validated to quantitative analyze of oxyresveratrol contents in aqueous and ethan...

OBJECTIVE To evaluate the correlation of total lymphocyte count (TLC) and CD4 cell count and the suitability of TLC as a surrogate marker for CD4 cell count of HIV-infected patients in China. METHODS Usefulness of TLC as a surrogate marker for a CD4 cell count <350 cells/mm(3) for HIV-positive patients in China was evaluated by 977 pairs of TLC and CD4 cell count from 977 outpatients. The res...

Background & Aim:Oxidative stresses caused by free radicals are known to promote many diseases such as inflammation and cancer; therefore, any plant product that can inhibit free radical production can play an important role in preventing diseases. We aimed to compare the fracture rate and the scavenging activity of free radicals, and the antioxidant composition of rol...

Thin-layer chromatography (TLC) has been a useful tool in the analysis of numerous urinary constituents; as in most applications of adsorption TLC, it is best used in conjunction with other chromatographic processes. The application of TLC to the resolution of polar urinary products derived from lipids is shown for the metabolism of a 14C-labeled fatty acid and a 14C-labeled glyceryl thioether....

Infection is one of the health problems and a disease that mainly causes death. Malaria parasitic infection transmitted through Anopheles sp. The female then besides malaria, other contaminants caused are bacteria such as Escherichia coli Staphylococcus aureus. This study aims to determine antioxidant, antimicrobial, antiplasmodial activity Sonchus arvensis L. ethyl acetate fractions. In vitro ...

Raw material, different formulations of foods, and dietary supplements of mate demands control of the content of bioactive substances for which high performance thin layer chromatography (TLC), described here, presents simple and rapid approach for detections as well as quantification. Using TLC densitometry, the following bioactive compounds were identified and quantified: chlorogenic acid (2....

To develop a chitosan-based nonviral gene carrier capable of delivering genes specifically into hepatoma cells, a bifunctional peptide composed of the TAT (transactivator of transcription) peptide and luteinizing hormone-releasing hormone (LHRH) was conjugated with low molecular weight chitosan, resulting in a TAT-LHRH-chitosan conjugate (TLC). TLC/DNA nanoparticles (TLCDNPs) were characterized...
