A novel, commercially viable process for the extraction of high purity (>70%), bioactive furostanolic saponins including protodioscin (>30%), from the seeds of fenugreek (Trigonella foenumgraecum) comprising essentially the steps of powdering of the natural material followed by a first extraction, an ion-exchange chromatographic purification and a second extraction using a novel composite solvent and drying of the product under defined conditions, the entire process being carried out at essentially neutral pH and low temperatures of less than 80° C.

The invention discloses a combiner capable of promoting the movement function and the sexual function. The combiner comprises 4-48 parts by weight of yohimbine hydrochloride, 5-150 parts by weight of icariin, 20-300 parts by weight of tribulus terrestris protodioscin, 10-600 parts by weight of eurycoma longifolia extract, 10-600 parts by weight of maca extract, 10-500 parts by weight of taurine, 10-100 parts by weight of zinc aspartate, 150-1350 parts by weight of magnesium aspartate and 0.1-5 parts by weight of vitamin B6.

The invention discloses an ethanol extract (PDE4) and total saponin (PDE5), which have anticancer activity, from paris dulongensis H. Li&Kurita, preparation methods of the ethanol extract (PDE4) and the total saponin (PDE5) and application of the ethanol extract (PDE4) and the total saponin (PDE5) to the preparation of a medicine for treating or preventing leukemia, a liver cancer, a lung cancer, a mammary cancer and a colon cancer, and provides a separation and identification method of chemical components in the PDE 5. Polyphyllin V, polyphyllin I, beta-ecdysone, protodioscin, parisaponin I and ginsenoside Rg1 are separated from the PDE5 and identified by adopting a separation method of chromatographic column chromatography and semi-preparative high performance liquid chromatography and an identification method of a mass spectrum and a nuclear magnetic resonance wave spectrum. The separation and identification method is used for clarifying main chemical components of the PDE5 for the first time, can be used for simply ad quickly obtaining the chemical components from the PDE5 through a provided method, and is used for reconstructing a quality control standard for the paris dulongensis H. Li&Kurita, the extract PDE4 of the paris dulongensis H. Li&Kurita or the total saponin PDE5 of the paris dulongensis H. Li&Kurita.

The invention relates to a traditional Chinese medicine extract and a preparation method thereof, in particular to a Ginseng saponin extract and a preparation method thereof. In the extract, the content of protodioscin is not less than 80 percent based on that of Ginseng saponin Rh2, the content of Ginseng saponin Rh1 and the Ginseng saponin Rh2 is not less than 50 percent, the content of Ginseng saponin Rh1 is between 1 and 20 percent and the content of the Ginseng saponin Rh2 is between 20 and 60 percent.

The present invention relates to the simple chemical process of synthesizing methyl or ethyl protodioscin with dioscin as material. The process includes the following steps: 1. protecting trisaccharide chain in dioscin; 2. oxidizing the completely protected dioscin; 3. introducing place 26 glucosyl radical; 4. eliminating protecting epoxy radical; 5. reducing place 16 carbonyl radical selectively with reductant; 6. eliminating all the protecting radicals under alkaline or hydrogenating condition to obtain methyl or ethyl protodioscin.

The invention discloses a method for enhancing the inhibitory activity of tyrosinase, which belongs to the technical field of deep processing of fruits and vegetables. The present invention forms tyrosinase inhibitor with the phenolic acid of 0.6-1.8mg / mL concentration and the saponin of 0.5-1.5mg / mL concentration; Described phenolic acid is quercetin, cinnamic acid, ferulic acid, gallic acid, Three kinds of isorhamnetin; the dosage ratio of any three components of phenolic acid is 1: (1‑10): (1‑10); the saponin includes one of protodioscin, diosgenin, and smilagenin . The present invention uses polyphenols and saponins to compound into tyrosinase inhibitors, the relative activity of tyrosinase after treatment can be as low as 5%, and the polyphenols of the three components can produce a synergistic effect; high temperature will desugar the saponins Kylation, to generate substances with high tyrosinase inhibitory effect such as polyphenolic polymers, thus greatly improving the inhibitory effect of tyrosinase inhibitors on tyrosinase.
