QUANTIFICATION OF CHEMICAL GROUPS AND QUANTITATIVE HPLC FINGERPRINT OF PORIA COCOS (SCHW.) WOLF

(1)Objective: In this study, a quantitative analysis of chemical groups (the triterpenoids, water-soluble polysaccharides, and acidic polysaccharides) and quantitative high liquid performance chromatography (HPLC) fingerprint of Poria cocos (Schw.) Wolf (PC) for quality control was developed.(2) Methodology: First, three main chemical groups, inclu

The data collected by floating cars is an important source for lane-level map production.Compared with other data sources, this method is a low-cost but challenging way to generate high-accuracy maps.In this here paper, we propose a data correction algorithm for low-frequency floating car data.First, we preprocess the trajectory data by an adaptive
