Simultaneous quantification of chlorogenic acid, quercetin, and kaempferol in leaves by CE and HPLC techniques: method validation and comparative study.

Two analytical methods, CE and HPLC, were developed, validated, and compared for simultaneously determining chlorogenic acid, quercetin, and kaempferol in leaves collected from twelve different sources of Thailand. The determination was accomplished by CE on the uncoated fused silica capillary tube and by HPLC on the ZORBAX Eclipse Plus C18 column. Chlorogenic acid was found to have the highest average amount in leaves, followed by kaempferol and quercetin, respectively.

Polyherbal formulation exerts wound healing, anti-inflammatory, angiogenic and antimicrobial properties: Potential role in the treatment of diabetic foot ulcers.

Diabetic foot ulcer (DFU) is a common and devastating complication in diabetic patients and is associated with an elevated risk of amputation and mortality. DFU remains a major therapeutic challenge due to poor understanding of its underlying pathogenesis. This complication is characterized by impaired wound healing; however, mechanisms causing this impairment are complicated and involve interactions between many different cell types and infections.

Standardization of L. aerial part and capillary electrophoresis quantitative analysis of its leonurine content.

The quality parameters of L. aerial part crude drugs were evaluated. Fifteen crude drugs were collected from various locations throughout Thailand.

cytotoxic, genotoxic, and antityrosinase activities of root.

Wall. (Leguminosae), locally known as Non-tai-yak or An-chan-pa, commonly distributed in tropical nations and Southeast Asia. Regarding traditional Thai medical system, roots carry out a potential in dermatology.

Quality evaluation with reference to clitoriacetal and antioxidant activities of root.

A new approach for the detection of cervical cancer in Thai women.

Objectives: The objective was to screen cervical cell samples of Thai women by using the Fourier-transform infrared (FTIR) spectrophotometry technique; the results were compared to the histologic diagnosis (gold standard).

Methods: FTIR spectrophotometry is a new technology for cervical cancer screening. Instead of detecting the morphological changes as used in Pap smear test, this technique detects, at the molecular level, structural changes of functional groups through the changes of the infrared absorption spectrum.

Accreditation of analytical laboratories and proficiency testing: experiences from Thailand on the issues of pesticide analysis.

Thailand, the economic growth of which largely depends on agriculture-based industry, recognizes the importance of international standards for harmonization of international food trade and for protection of human health from chemicals used as food additives or those present as contaminants. Pesticides which are widely used in Thailand are the anticholinesterase pesticides, pyrethroids, coumarin derivatives, bipyridinium salts, and to some extent organochlorine compounds such as DDT in malaria control. Proficiency testing and accreditation of laboratories are recognized as effective means to ensure quality and validity of data and to enable adequate risk assessment of pesticide residues in food, work environment and environment in general.
