Abstract
Fat and wax (F&W) compounds have to be removed from raw plant materials
before pectin and oligosaccharides (OS) can be isolated. In this research, the
mixtures of F&W, and polyphenols and sugars were firstly separated from the
roots of Eremurus hissaricus (Eremurus h.), and the byproducts of fruit
processing, such as apple pomace, sunflower head residues, and grape seeds,
etc., using hexane/ethanol or ethyl acetate as leaching reagents at various ra-
tios of liquid to solid. The resultant mixtures were then extracted with an
ethanol/water mixture to separate F&W from polyphenols and sugars. It was
found that the F&W yield decreased in the sequence of apricot > apple > sun-
flower head residues > peach > pumpkin with 21.84% in apricot as the highest
number. The amount of alcohol-water soluble compounds (AWSC), mainly
polyphenols and sugars, decreased in the sequence of peach > sunflower head
residues > apricot > pumpkin > apple. No inter-dependence of AWSC and
F&W was identified.

1. Introduction
Before extracting pectin and oligosaccharides (OS) and other biologically active
components from plant materials, the raw materials should undergo a defatting
process in order to intensify the extraction and isolation processes. Fats and
waxes have been used in various formulations for soap-making, skin and hair
care, cooking and healing purposes. They give consistency and stability to body
butters, healing balms, ointments, lip balms and creams. In addition, because
waxes are not absorbed by the skin, they provide an outer layer of protection and
