Since ancient times, herbal medicines (HM) have played a vital role in worldwide healthcare systems. It is therefore critical that thorough evaluation of the quality and control its complicated chemical makeup be conducted, order to ensure efficacy safety. The notion HM prints, which aim acquire full characterization compound matrices, has become one most persuasive techniques for during last f...

Demand for high quality Basmati rice has increased significantly in the last decade. This commodity is highly vulnerable to fraud, especially post COVID-19 era. A unique two-tiered analytical system comprised of rapid on-site screening samples using handheld portable Near-infrared NIR and laboratory confirmatory technique a Head space gas chromatography mass spectrometry (HS-GC-MS) strategy unt...

Deep spectral modelling for regression and classification is gaining popularity in the chemometrics domain. A major topic deep learning (DL) of data choice optimization neural network architecture suitable specific task modelling. Although there are several recent research articles already available chemometric domain showing advanced approaches to modelling, currently, a lack hands-on tutorial...

Laser-induced breakdown spectroscopy (LIBS), accompanied by chemometric data analysis, is used to identify and classify gemstones of various hardness. The study involves several gemstones: amethyst, aquamarine beryl, bloodstone citrine, diopside, enstatite. Their hardness determined through a correlation utilizing the spectral intensity ratio ionic atomic lines an identified element in LIB spec...

Hyperspectral imaging covering the spectral range of 384-1034 nm combined with chemometric methods was used to detect Sclerotinia sclerotiorum (SS) on oilseed rape stems by two sample sets (60 healthy and 60 infected stems for each set). Second derivative spectra and PCA loadings were used to select the optimal wavelengths. Discriminant models were built and compared to detect SS on oilseed rap...

Danshen, the dried root of Salvia miltiorrhiza Bge., is a widely used commercially available herbal drug, and unstable quality of different samples is a current issue. This study focused on a comprehensive and systematic method combining fingerprints and chemical identification with chemometrics for discrimination and quality assessment of Danshen samples. Twenty-five samples were analyzed by H...

It is possible to classify various propolis samples based on their botanical or geographic origins, since environmental conditions and the harvest season have an impact chemical ingredients that make up propolis. In current research, determination geographical classification of according mineral/metal content are addressed. Acid digestion was employed for recovery inductively-coupled plasma-opt...

The determination of food geographical origin has been an important subject of study over the past decade, with an increasing number of analytical techniques being developed to determine the provenance of agricultural products. Agricultural soils can differ for the composition and the relative quantities of mineral nutrients and trace elements whose bioavailability depends on soil properties. T...
