Current Bioactive Compounds - Volume 7, Issue 2, 2011

This issue is dedicated to scientists belonging to the fields of phytoanalysis, -chemistry and -pharmacy, respectively. Today there is an increasing need for the qualitative and quantitative analysis of medicinal plants since each of them is composed of a great number of beneficial compounds with different pharmacological activity. In case of medicinal plants, the identification, discrimination and classification are especially diffic Read More

Volatile chemical compounds responsible for the aroma of plant materials are derived from a number of different biochemical and chemical pathways. These chemical compounds are formed during plant metabolism, processing (i.e. fermentation) and post-harvest storage. Not surprisingly, there are a large number of chemical classes of compounds found in plant materials which are present at varying concentr Read More

Traditional Chinese Medicine (TCM) is becoming more and more popular all over the world. Novel analytical tools for quality control are highly demanded enabling analysis starting at breeding and ending at biological fluids including urine or serum. Compared to analytical separation methods (chromatography, electrophoresis) near-infrared spectroscopy (NIRS) allows analyzing matter of interest non-invasively, fast a Read More

During the whole human history and particularly in the recent years, various plants of medicinal importance are being utilized for curing various diseases and ailments. A huge world population knowingly or unknowingly is using herbal medicines. The investigations have already shown that there is a strong correlation between current therapeutics and traditional plants. However, there are renewed attempts in phytochemist Read More

The aim of this paper was to review the ability of NIR spectroscopy to determine fermentative volatile compounds, oak volatile compounds, ethylphenols, haloanisoles, and halophenols in aged red wines, which are the highest quality and reputation in the market. Six hundred wines from four different Spanish geographic zones aged during different storage time (at least 6, called as “crianza”, 12, called as “reserva”, and 1 Read More

Fourier Transform Infrared (FTIR) spectroscopic imaging and mapping techniques have become essential tools for the detection and characterization of the molecular components of biological tissues and the modern analytical techniques enabling molecular imaging of complex botanical samples. These techniques are based on the absorption of IR radiations by vibrational transitions in covalent bonds and their Read More

The application of IR spectroscopy in herbal analysis is still limited when compared to other areas (food and beverage industry, microbiology, pharmaceutical etc). The aim of this work is to adopt the fingerprinting through Fourier Transform Infrared (FTIR) technique to measure the polyphenols of six seagrasses of Gulf of Mannar, India. The representative IR spectra from the mid-infrared region (4000-400 cm-1) for Read More

Previously, we showed that extracts of ripe seasonal sweet corn tassels possess anti-irritant and anti-oxidant activities. The chemical identification of corn tassel bioactives was investigated by HPLC analysis. The hydroalcoholic extracts are composed primarily (>85%) phenolic-type compounds. The predominant component from C18 columns were concentrated by reverse phase chromatography and purified to greater than 97- Read More
