Abstract: A preparation method of a Lentinula edodes polysaccharide rich in ?-glucan includes: (1) extracting the Lentinula edodes polysaccharide to obtain a filtrate; (2) concentrating the filtrate to obtain a supernatant; (3) precipitating a crude Lentinula edodes polysaccharide from the supernatant using anhydrous ethanol to obtain a first precipitate; and (4) purifying the first precipitate to obtain the Lentinula edodes polysaccharide. The Lentinula edodes polysaccharide rich in the ?-glucan has stable quality, and its yield, polysaccharide content and ?-glucan content are significantly improved compared with water extraction and alcohol precipitation methods in the related art. In vitro pharmacological experiments prove that the Lentinula edodes polysaccharide rich in the ?-glucan has good anti-inflammatory activity and can be applied to preparation of drugs or health foods.

Abstract: Embodiments of the present invention disclose a method and an apparatus for providing folder project information based on a touch operation. The method includes: determining positions of touch points on a display screen; calculating, according to the positions of the touch points, a size of a zoomed display area of a folder item; acquiring a data source that is of the folder item and needs to be displayed, where the data source of the folder item corresponds to the size of the zoomed display area; and displaying the folder item according to an acquired data source and the size of the zoomed display area. According to the embodiments, the level of detail of folder item information in the window may be quickly changed without the need of page switching, thereby improving user experience with simple and quick operation.
