NOVELTY - Extracting beta-sitosterol involves preparing corn oil by steam distillation. Corn debris is removed. The obtained corn is washed, crushed to 20 meshes and placed on support plate with distilled water. The obtained liquid material is poured into charging pot. The pot is added injected with water at bottom above 20-30cm. The charging pot is sealed. The pot is heated such that low pressure saturated steam is generated for 0.5-1 hours. The corn raw material is covered with layer of water vapor then pan is distillated. Oil-water mixture at upper part of the pot is distilled off.    USE - Method for extracting beta-sitosterol from corn silk (claimed).    ADVANTAGE - The method enables to extract pure beta-sitosterol in eco-friendly, cost-effective and simple manner, and improves productivity and extraction rate.    DETAILED DESCRIPTION - Extracting beta-sitosterol from corn silk involves preparing corn oil by steam distillation. Corn debris is removed. The obtained corn is washed, crushed to 20 meshes and placed on support plate with distilled water. The obtained liquid material is poured into charging pot. The pot is added injected with water at bottom above 20-30cm. The charging pot is sealed. The pot is heated such that low pressure saturated steam is generated for 0.5-1 hours. The corn raw material is covered with layer of water vapor then pan is distillated. Oil-water mixture at upper part of the pot is distilled off. The obtained corn is introduced into condenser and cooled to room temperature to obtain distillate. The distillate is imported into oil and water separator for still clarification. The oil and water layers are separated. The obtained material is subjected to supercritical carbon dioxide with predetermined temperature and pressure of fluid. The material is continuously injected from extraction purification tower reactor into bottom of tower. The carbon dioxide temperature and pressure from the bottom of the tower to upside remains constant. The corn oil is collected into the tower from the sump pump and mixed with supercritical carbon dioxide. The obtained material is purified and extracted by throttle pressure separator III import. The separator at its bottom contains precipitate of beta-sitosterol, which is collected.
