Home Azerbaijan Technologies Isolation of High-Purity Preparation

Isolation of High-Purity Preparation β -SITOSTERIN from Narthamus L


Preparation β-sitosterin (С29Н52О) is a white needle crystal soluble in chlorophorm, methanol but insoluble in water. Methods of its isolation from sunflower seeds, bean, larch timber and grape pressing are well-known.

Innovative Aspect and Main Advantages

  1. Wide-spread, readily accessible and cost-effective raw material (cultural and wild species of Сarthamus L.);
  2. High purity (97%);
  3. Simplicity of method of isolation;
  4. Time and reagents saving;
  5. Economic effect:

Areas of Application

  1. In medicine: decreases the level of cholesterol in blood, suppress the resorption of exogenous and endogenous cholesterol, prevents the absorption of cholesterol in intestines;
  2. In cosmetology: plays role in restoring of structure epidermis and improving moisture-holding properties of skin);
  3. In scientific-research work: as reagents.

Stage of Development

Introduction certificates were obtained as a result of producing of β-sitosterin jointly with RPA “BiochemReagent”, Olayna Plant Chemical Reagents in 1979-1993 years.

Polarized lenses are offered for snow and water enthusiasts, lending an
extra degree of protection from glare. The frames are
smaller (since women normally have smaller faces
then men) and can be less light leakage.

It may be the first shoe of its kind that is
intended through environmentally friendly conditions. There are occasions where each every person can
try buying some of air Jordan sneakers.
