  • Patent number: 12122744
    Abstract: The present application relates to a technical field of separating kavalactone and flavokawain, and in particular, to a method for separating flavokawain and kavalactone, kavalactone, and microencapsulated kavalactone. The separation method includes: S1. grinding root of piper methysticum, extracting by supercritical carbon dioxide and collecting a residue for later use, in which an extraction temperature is 45-50° C. and an extraction pressure is 4-8 MPa; S2. extracting the residue by supercritical carbon dioxide, and collecting extracted oil for later use, in which an extraction temperature is 60-80° C. and an extraction pressure is 20-50 MPa; S3. performing re-extraction and adsorption on the extracted oil to obtain a primary product of the kavalactone; and S4. crystallizing the primary product of kavalactone to obtain the kavalactone. The obtained kavalactone is used for microencapsulated kavalactone.

  • Patent number: 10973209
    Abstract: The current invent relates to the construction and application of a three-line breeding system in the Peruvian scallop×bay scallop hybrids. The said three-line consists of a male sterile line, a maintainer line and a restorer line. A combination of male sterile line and maintainer line is obtained by continuously backcrossing the male sterile individuals selected from F1 inter-specific hybrid families with sperm of the selfing family of the sperm-providing bay scallops until the progenies are all male sterile. The restorer line is obtained by continuously backcrossing selected individuals from the male sterile line with sperm of the selfing family of a bay scallop until the progenies are all hermaphroditic and exhibit excellent production traits. Commercial male sterile brood stocks are produced by backcrossing the male sterile line with the maintainer line and commercial hybrid spats are produced by backcrossing the male sterile line and the restorer line.

  • Patent number: 10918093
    Abstract: The current invent relates to the construction and application of a three-line breeding system in the bay scallop southern subspecies x Peruvian scallop hybrids. The said three-line consists of a male sterile line, a maintainer line and a restorer line. A combination of male sterile line and maintainer line is obtained by continuously backcrossing the male sterile individuals selected from F1 inter-specific hybrid families with sperm of the selfing family of the sperm-providing Peruvian scallops until the progenies are all male sterile. The restorer line is obtained by continuously backcrossing selected individuals from the male sterile line with sperm of the selfing family of a Peruvian scallop until the progenies are all hermaphroditic and exhibit excellent production traits. Commercial male sterile brood stocks are produced by backcrossing the male sterile line with the maintainer line and commercial hybrid spats are produced by backcrossing the male sterile line and the restorer line.

  • Publication number: 20170245478
    Abstract: The current invent relates to the construction and application of a three-line breeding system in the Peruvian scallop×bay scallop hybrids. The said three-line consists of a male sterile line, a maintainer line and a restorer line of the bay scallop×Peruvian scallop hybrids. Herein the Peruvian scallop×bay scallop hybrids are hybrids resulted from the eggs of the Peruvian scallops fertilized with sperm of the bay scallops. In constructing the three-line, male sterile individuals are selected from F1 inter-specific hybrid families and continuously backcrossed with sperm of the selling family of the sperm-providing bay scallops of the F1 hybrid to obtain a combination of male sterile line and maintainer line whose hybrid progenies are all male sterile. Then selected individuals from the male sterile line are continuously backcrossed with sperm from the selfing family of a bay scallop until the resulted progenies are all hermaphroditic and exhibit excellent production traits.
