  • Patent number: 10196417
    Abstract: A baicalin magnesium compound and methods for preparing and extracting the same. The method for preparing the baicalin magnesium compound includes steps of preparation of a baicalin suspension, preparation of a magnesium ion-containing suspension, reaction and drying. The method for extracting the baicalin magnesium compound includes steps of pretreatment of macroporous resin, extraction, adsorption and elution, concentration and drying and purification. The methods restores the baicalin to the original form as found in radix scutellariae, and the baicalin magnesium compound may be used as a substitute for the baicalin in pharmaceutical applications. As compared to the baicalin, the baicalin magnesium has a greatly increased solubility, faster adsorption rate and higher oral bioavailability. The baicalin magnesium compound may also be easily formulated as a water-soluble injection or a powder injection.

  • Publication number: 20140174137
    Abstract: A lock structure including a base and a door portion, a lock mechanism and a locking section, and a first mating element is provided. The door portion is pivotally connected to one end of the base portion by a pivot and is switched between an open and a close status. One of the base portion and the door portion comprises a first opening, the other comprises a first securing element close to the first opening. The lock mechanism and the locking section are disposed at the door and the base portion, respectively, and correspond to each other. The first mating element comprises a first engaging portion selectively connected to or detached from the first opening, wherein the first securing element restricts the first engaging portion from being detached from the first opening when the first engaging portion is located at the first opening and the door portion is closed.
