Cold extraction methods with ethanol applied to the flavedo of Citrus fruits have been commonly for preparation several liquors. In order obtain optimization and then best ratio functional ingredients in extract, grandis Osbeck (pummelo) was subjected a maceration absolute at room temperature as well 40 °C. The kinetics were monitored by UV–VIS spectroscopy, chemical fingerprint characteristic ...

Two methods are available for ascertaining the size, shape, sequence and relations of the several parts of a renal tubule of mammalia, namely, reconstruction by the wax-plate method and maceration of kidney substance to an extent permitting isolation of tubules or tubule segments. Of these two methods that of reconstruction is the more satisfactory, within the limits of its applicability, since...

Solid bath soap is a cosmetic preparation to remove dirt from skin surfaces. Kaffir lime peel good natural ingredient for health. The aim of this study was produce solid thick extract kaffir with several concentrations. made by maceration dissolving 500 grams powder 96 % ethanol as solvent much 1,000 mL 2x24 hours and concentrated using rotary evaporator at C. the method used in making cold pro...

Since Yamagiwa and Itshikawa in 1915 (14) succeeded in inducing cancer in rabbits by means of coal tar, investigators have been aware that the induced cancers appear within fairly sharply defined loci. Most data secured by chemical analysis do not supply direct information about these foci; because, in order to obtain enough material for analysis the treated epidermises of several mice are usua...

This work proposes the elaboration of a product based on maceration Sherry Vinegar together with pineapple in order to extract certain volatile compounds that can be found pineapples, giving final new organoleptic properties and increased polyphenolic content. Maceration trials were carried out application microwaves ultrasound, which reduced time from traditional three-day solid-liquid just fe...

The method of cold maceration was used in the extraction Justicia secunda starting with a non-polar (hexane) to more polar solvent. crude extracts hexane, ethyl acetate, acetone, and methanol from stem were obtained using polarity guided method. Lupeol Lauric acid are two well-known compounds that discovered when portion acetate extract J. subjected spectroscopic (1H NMR) structural elucidation...

This study aims to investigate the biological activities related to hair loss of Equisetum debile extracts, including 5α-reductase inhibition, interleukin-6 (IL-6) secretion reduction, and anti-oxidation. E. debile extracts were obtained by maceration in various solvents. Crude extract (CE) was obtained by maceration in 95% ethanol. Chlorophyll-free extract (CF) was the CE which of the chloroph...
