Abstract: A method of extracting myricetin from Xanthoceras sorbifolia Bunge is provided. The method includes: step 1, baking obtaining Xanthoceras sorbifolia Bunge crude powder; step 2, mixing the crude powder with a counter-current extraction solution to perform a counter-current extraction to obtain a filtrate and a filter residue; step 3, mixing the filter residue with a solvent to obtain a first mixture, and heating the first mixture to reflux for extraction to obtain an extraction liquid; step 4, mixing the extraction liquid and the filtrate, and concentrating under reduced pressure to obtain a concentrated solution; and step 5, separating and eluting the concentrated solution to obtain an eluent, then drying the eluent to obtain the myricetin.

Abstract: The disclosure relates to the technical field of extraction of an active ingredient from traditional Chinese medicine, and provides a method of extracting myricetin from Xanthoceras sorbifolia Bunge.

Abstract: A computer-aided design (CAD) system may support detection of internal channel networks for 3D printing and may include a CAD model access engine and a channel network detection engine. The CAD model access engine may access a CAD model of a physical object to be constructed through 3D printing. The channel network detection engine may detect an internal channel network included in the CAD model of the physical object, including by identifying channel openings along a surface of the CAD model that satisfy an opening size threshold and recursively identifying internal faces of the CAD model that form the internal channel network, wherein the internal faces are faces of the CAD model that are internal to the surface of the CAD model. The channel network detection engine may also perform a channel verification on the identified internal channel network to support the 3D printing of the physical object.

Abstract: Methods for computer-aided design and corresponding systems and computer-readable mediums. A method includes receiving a CAD model including a plurality of intersecting fluid channels, and determining a fluid inlet for the fluid channels. The method includes displaying possible fluid flow directions at an intersection of fluid channels. The method includes automatically adding a cooling fitting to at least one of the fluid channels of the CAD model in response to a user selection of one of the possible fluid flow directions.
