The study of herbs extracts composition in the drying process

Medicinal and flavoring herbs are widely used in herbal medicine. Various methods to study plants, evaluate the efficiency of extraction biologically active target components. The process control is carried out by chromatographic, spectral methods. search for new fast, affordable, simple analysis currently relevant. dry droplet weighing method extract was proposed as an alternative known herb parsley extracts four (spectrophotometry, refractometry, thin layer chromatography direct drop weighing) out. objects were fresh protected ground Indana brand dried parsley. Fresh change chemical composition water-alcohol monitored 16 days. Compounds identified differential spectra. It found that amount substances extracted from greater than sample after 12 days drying. mobile phase fast selected. best separation chlorophylls related occurs at a volume ratio toluene ethyl alcohol 5:5 6:4. sensitivity refractometry does not allow determining difference extracts. Using piezoquartz microweighing, it proved with increase drying time parsley, number compounds increases. most sensitive i.e. MCNano-WPQ-8 device can be non-laboratory conditions express monitoring plant materials small manufactures. simpler, cheaper, more compact other devices. approach tested on various types phyto raw materials.
