This invention belongs to the field of genetic engineering and biotechnology, specifically relating to a β-glucosidase PO3 for the conversion of rare ginsenosides, its preparation method, and its applications. This invention obtains β-glucosidase PO3 by PCR amplification using genomic DNA of *Xanthomonas pseudoepiplo* TY3-10 as a template. The results of the examples show that this enzyme can not only convert total ginsenosides into rare ginsenosides F2, C-O, C-Mx1, and C-Mc1, but also convert ginsenoside Rb1 into F2, ginsenoside Rb2 into C-O, ginsenoside Rb3 into C-Mx1, and ginsenoside Rc into C-Mc1; it also exhibits excellent catalytic performance and high expression efficiency, possessing extremely high application value and commercial prospects.

The invention discloses an SNP molecular marker, a KASP primer, a kit and a method for detecting the content character of ginsenoside Rc in panax notoginseng, and elaborates the practical application of the kit in breeding of the content character of ginsenoside Rc in panax notoginseng. The SNP molecular marker involved in the invention is SNP-218351403, the marker is located on a chromosome 1 (Chr1), and the specific position is the 218351403 basic group. In addition, the base mutation type of the SNP marker is G / A. According to the invention, a set of KASP (Kompeste Allele Specific PCR) primer combination is developed, and the combination can be used for accurately distinguishing pseudo-ginseng plant individuals with high ginsenoside Rc content and pseudo-ginseng plant individuals with low ginsenoside Rc content. By using the primer combination, the molecular-assisted marker breeding technology can be effectively applied to the breeding process of the panax notoginseng plant, the operation is simple and convenient, the cost is lower, the breeding period of a new variety is shortened, and the primer combination can be used for long-term breeding tracking and variety tracing. Therefore, the method disclosed by the invention is of great significance in accelerating precise breeding of the panax notoginseng with high ginsenoside Rf content.

The application provides a multi-component quantitative analysis method of anti-aging tablets, acetonitrile-0.1% formic acid aqueous solution is used as a mobile phase, an HSS T3 chromatographic column is used for target compound separation, and 13 active components in the anti-aging tablets are simultaneously determined in an MRM mode by using an electrospray ionization triple quadrupole mass spectrometer, the linear range of the 13 active components is 0.4-100 ng / mL, the linear range of ginsenoside Rb1, ginsenoside Rb2, ginsenoside Rc, ginsenoside Rd, ginsenoside Re, ginsenoside Rf and ginsenoside Rg1 is 4-1000 ng / mL, the method has high sensitivity, strong specificity and good reproducibility, and realizes simultaneous quantitative analysis of the 13 active components in the anti-aging tablets.

The application discloses application of ginsenoside Rc and derivatives or salts thereof in preparation of a medicine for preventing and / or treating early lung metastasis of Lewis lung cancer and / or combination with other tumors. The ginsenoside Rc of the application shows better prevention and treatment effects on early lung metastasis of Lewis lung cancer and higher safety than cisplatin in a tumor-bearing mouse model, and no adverse reactions are found.

The invention provides a method for determining the content of multiple components in an Aidi preparation, and belongs to the technical field of medicines. The Aidi preparation is prepared from traditional Chinese medicinal materials including ginseng, cantharides, astragalus membranaceus and acanthopanax. The content determination method comprises the following steps: simultaneously determining cantharidin, ginsenoside Rg1, ginsenoside Re, ginsenoside Rb1, ginsenoside Rc, ginsenoside Rd, isofraxidin, syringin, formononetin, astragaloside, chlorogenic acid, eleutheroside E, calycosin-7-glucoside, astragaloside II, neochlorogenic acid, cryptochlorogenic acid and eleutheroside E1 in the Aidi preparation by adopting liquid chromatography-mass spectrometry; the composition is prepared from effective components such as ginsenoside F3, ginsenoside Rg2, azelaic acid and the like. Compared with the prior art, the method has the advantages that the contents of the 20 effective components in the Aidi preparation are simultaneously measured under the same chromatographic condition through liquid chromatography-mass spectrometry, the method is convenient and rapid, the requirement for product quality detection is greatly improved, the method is more suitable for quality control of drugs in the future, and the drug quality and the clinical drug effect are guaranteed.
