Our objective was to create a calibration model for rapid determination of the oil in whole Milk Thistle seeds using the method Fourier Transform Near Infrared (FT-NIR) Spectroscopy. The seeds from different distributors and dealers from several European countries and from the harvests 2010, 2011 and 2013 were processed by Soxhlet extraction in Det-Gras N instrument and its FTNIR spectra were c...

A new method of ultrahigh pressure extraction (UPE) was used to extract the ginsenosides from Panax quinquefolium L. (American ginseng) root at room temperature. Several solvents, including water, ethanol, methanol, and n-butanol were used in the UPE. The ginsenosides were quantified by a HPLC equipped with UV-vis detector. The results showed that ethanol is the most efficient solvent among the...

Gloriosa superba is a very important medicinal plant that is used for the treatment of diseases like Gout, arthritis, cancer and act as anthelmintic, antimitotic and antiabortive agent. Its tuber is a great source of Colchicine for the pharmaceutical industries and requires drying before extraction. The accelerated artificial drying technique using Microwave Vacuum oven was evaluated with other...

Objective of the study was to assess the antidiabetic activity of a polyherbal formulation in alloxan induced diabetic rats. Methods: The antidiabetic activity of a polyherbal formulation in alloxan induced diabetic rats was assessed using Alloxan βcytotoxin induced chemical diabetes in a wide variety of wister albino rats. Result: The polyherbal formulation contain the following plants leaves ...

Background and purpose: Allium (Liliaceae) genus has about 600 spp. This investigation was designed to study the impact of extraction methods on total phenolic and flavonoid contents, antioxidant, and antihypoxic properties of A. ampeloprasum in mice. Materials and methods: The aerial parts were extracted by three different methods, i.e. maceration, ultrasonic assisted (UAE) and Soxhlet assist...

An alternative method for the extraction of polychlorinated biphenyls (PCBs) in ash samples, which is less time and solvent consuming than Soxhlet extraction, is presented. A study was carried out to evaluate the possibilities of microwave-assisted extraction (MAE) to determine exactly which parameters affect the efficiency of the process, since direct extrapolation of extraction conditions for...

In the present study, supercritical carbon dioxide (SC-CO(2)) extraction of seed oil from winter melon (Benincasa hispida) was investigated. The effects of process variables namely pressure (150-300 bar), temperature (40-50 °C) and dynamic extraction time (60-120 min) on crude extraction yield (CEY) were studied through response surface methodology (RSM). The SC-CO(2) extraction process was mod...
