The Flos Lonicerae-Fructus Forsythiae herb couple is the basic components of Chinese herbal preparations (Shuang-Huang-Lian tablet, Yin-Qiao-Jie-Du tablet and Fufang Qin-Lan oral liquid), and its pharmacological effects were significantly higher than that in Flos Lonicerae or Fructus Forsythiae, but the reasons remained unknown. In the present study, pattern recognition analysis (hierarchical c...

The study uses 30 years of the third generation Advanced Very-High-Resolution Radiometer (AVHRR) NDVI3g monthly data from 1982 to 2012 identify natural clusters and important driving factors upstream watersheds in Taiwan through hierarchical cluster analysis (HCA) redundancy (RDA), respectively. Subsequently, as a result HCA, six were identified based on NDVI data, delineating unique characteri...

Macroalgae are an essential basic ingredient for many industries from which numerous derived products with great economic value manufactured. Each macroalga has a unique composition that might provide specific physical and chemical information can be used as markers authentication. Their compositions may differ depending on different factors, including geographical regions. Unsupervised explora...

Aquatic oligochaetes are very common in streams, and are used as biological assessment indicators as well as in the biological management of organic-enriched systems. In this study, we analyzed the effects of environmental factors influencing the distribution of aquatic oligochaetes Limnodrilus hoffmeisteri in streams. We used 13 environmental factors in three categories (i.e., geography, hydro...

The combinations of inductively coupled plasma-optical emission spectrometry (ICP-OES) and three classification algorithms, i.e., partial least squares discriminant analysis (PLS-DA), least squares support vector machine (LS-SVM) and soft independent modeling of class analogies (SIMCA), for discriminating different brands of Iranian bottled mineral waters, were explored. ICP-OES was used for th...

The main objective of this study was to use infrared spectroscopy to identify vegetable oils used as raw material for biodiesel production and apply multivariate analysis to the data. Six different vegetable oil sources--canola, cotton, corn, palm, sunflower and soybeans--were used to produce biodiesel batches. The spectra were acquired by Fourier transform infrared spectroscopy using a univers...

Twenty-nine Korean wheat cultivars were analyzed for 8 important minerals (Cu, Fe, Mn, Zn, Ca, K, Mg and P) using Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES). A hierarchical cluster analysis (HCA) was applied to classify wheat cultivars, which has a similarity in mineral compositions. The concentration ranges of the micro-minerals Cu, Fe, Mn, and Zn: 0.12~0.71 mg/100 g, 2....

In this study, powder was obtained from yellow and purple-fleshed potatoes by microwave hot air drying the effects of methods on total phenolic compounds, monomeric anthocyanin, color, antioxidant activity, starch ratio vitamin C were determined. It observed that process caused an increase in bioactive components purple-colored samples, no significant differences determined terms yellow-colored...

Myrtle (Myrtus communis L.) is an aromatic and medicinal plant spreading in the Mediterranean area. The main uses of myrtle plants are liqueur essential oil production with several biological properties. A large part properties these products due to phenolic compounds. Twenty-two cultivars originating from areas Sardinia Island cultivated at same site were analysed for compounds determination. ...

The present study was performed to assess the quality of Potentilla fruticosa L. sampled from distinct regions of China using high performance liquid chromatography (HPLC) fingerprinting coupled with a suite of chemometric methods. For this quantitative analysis, the main active phytochemical compositions and the antioxidant activity in P. fruticosa were also investigated. Considering the high ...
