Study of the extraction process of the Pleurotus citrinopileatus mushroom and evaluation of the biological activity of the extract

Pleurotus citrinopileatus, also known in Vietnam as golden oyster mushroom, is a food rich protein, fiber, essential amino acids, carbohydrates, water-soluble vitamins, and minerals. In particular, the composition of yellow mushrooms, there β -1.3 - glucan with high biological activity an active ingredient contributing to intense stimulation immunity. The study researched process extracting citrinopileatus mushroom by assisted extraction combination ultrasonic waves pyrolysis aqueous solvent at 100°C, then evaluation extract orient application functional foods support cancer treatment. Some conditions documented through are follows: used for was water, sodium chloride salt catalyst, ratio 1g NaCl:100 ml solution, sample ultrasonically processed 60 min magnetic stirred 100°C 2 hours, concentration Na2CO3 participating reaction 20%, HCl 2M, IPA treatment/mushroom residue 1:1 (v/v). From powder, research team successfully obtained β- glucan.
