摘要

Ganoderma lucidum known as Reishi in Japanese and Lingzhi in Chinese, are commonly used in Vietnam with excellent beneficial health effects. Polysaccharides are usually considered as their main active components. To date, a careful comparison of crude polysaccharides extraction methods from the Ganoderma lucidum, which is grown in Vietnam, has not been performed. In this study, the crude polysaccharides from fruiting bodies of Vietnamese Lingzhi collected from the South of Vietnam were analyzed and compared based on monitoring the absorbance of the samples in 490 nm, as well as enzymatic, microwave and ultrasonic methods with different surveyed parameters, such as: concentration of enzyme, microwave frequencies, extraction time, extraction temperature, ratio of sample and water. The results showed that the highest crude polysaccharide was extracted when using cellulase in enzymatic method.
