ULTRASONICATION EXTRACTION AND SOLID PHASE EXTRACTION CLEAN-UP FOR QUANTIFICATION OF ARISTOLOCHIC ACID I IN THE THAI HERBAL ANTITUSSIVE 3 FORMULA BY HIGH PERFORMANCE LIQUID CHROMATOGRAPHY WITH PHOTODIODE ARRAY DETECTION

Objective: To establish a reliable High Performance Liquid Chromatography method with photodiode array detection (HPLC-PDA) and a suitable extraction method for identification and quantification of Aristolochic acid I (AA-I) in 3 different sample types, i.e.Aristolochia tagala Cham.(ATC), Thai Herbal Antitussive 3 Formula (ATF3), and Thai Herbal An

In systems with several effectors, the results of dose-response (DR) experiments are usually assessed by checking them against two hypotheses: independent action (IA) and concentration addition (CA).Both are useful simplifications, but do not represent the only possible responses, and avoid to a large extent the analysis of the interactions that ar

The fifth-generation (5G) system utilizing millimeter wave is available in Japan, but more bandwidth is demanded by the mobile phone operators to accommodate the demand for high data rate.Allocation of the vacant spectrum is impossible due to the past spectrum allocation to other radio systems.For example, 24.25-27.5 GHz has been allocated for the

Measuring the performance of food and agricultural systems is critical for their transformation towards a sustainable, healthy, and resilient future.To guide decisions and ensure agrifood systems deliver multiple functions, a holistic systems perspective is needed.Previous reviews of assessment approaches have focused primarily on the farm level an
