767 results about "Crocin" patented technology

Crocin is a carotenoid chemical compound that is found in the flowers crocus and gardenia. Crocin is the chemical primarily responsible for the color of saffron. Chemically, crocin is the diester formed from the disaccharide gentiobiose and the dicarboxylic acid crocetin. When isolated as a pure chemical compound, it has a deep red color and forms crystals with a melting point of 186 °C. When dissolved in water, it forms an orange solution.

Method used for preparing high-purity gardenoside and crocin from gardenia jasminoides ellis

InactiveCN103951718AHigh puritySolve the problem that the purity is low and must be purified by repeated adsorptionSugar derivativesNatural dyesGenipinMixed materials
The invention relates to a method used for preparing high-purity gardenoside and crocin from gardenia jasminoides ellis, and belongs to the technical field of food and medicine. The method comprises following steps: a, gardenia jasminoides ellis is collected, and is extracted at a temperature of 40 to 70 DEG C, an obtained extracted solution is cooled to room temperature, active carbon or diatomite is added, and an obtained mixture is filtered and concentrated so as to obtain an extractum; b, the extractum is dissolved in water, pH value is adjusted to 7.8 to 9, an obtained solution is processes by using a MCI gel chromatographic column, is allowed to stand, and is subjected to elution with water, an obtained mixed material is subjected to elution with an ethanol solution with a mass percent concentration of 5 to 30% so as to obtain an eluent containing gardenoside, and an obtained product is subjected to elution with an ethanol solution with a mass percent concentration of 60 to 90% so as to obtain an eluent containing crocin; c, the eluent containing gardenoside is concentrated, is dissolved in ethyl acetate or absolute ethyl alcohol, and is subjected to crystallization so as to obtain high-purity gardenoside; the eluent containing crocin is concentrated and dried so as to obtain high-purity crocin. Beneficial effect of the method is that: purity of gardenoside and purity of crocin are both high.

Rotation planting technology for saffron crocus with rice, peony and green vegetables

ActiveCN105230333ASolve the problem of continuous cropping soil obstaclesEfficient couplingPlant cultivationCultivating equipmentsContinuous croppingGreenhouse
The invention discloses a rotation planting technology for saffron crocus with rice, peony and green vegetables. According to the planting technology, saffron crocus is in alternate rotation with rice in a field, saffron crocus is in rotation with peonies and green vegetables in a greenhouse, and the crops for rotation are linked in the mode that in the first season, rice is sown in the field in the middle ten days of May, and harvesting is conducted in the last ten days of November; in the second season, saffron crocus is sown in the first ten days in December, bulbs are harvested in the first ten days of May in the next year and put on shelves in July in the greenhouse, flowers are harvested in the last ten days in November, and the shelves are removed; in the third season, peonies are put into pots in the first ten days of December, enter the greenhouse for flower forcing and are harvested around the spring festival; in the fourth season, green vegetable are planted in the greenhouse from the middle ten days of February to the last ten days of June for multiple batches. The rotation planting technology comprises the specific steps that firstly, rice is planted; secondly, saffron crocus is planted; thirdly, peonies are planted; fourthly, green vegetables are planted. By means of the rotation planting technology, the problem of soil impediment caused by continuous cropping of rice, saffron crocus and vegetable, efficient coupling of water and fertilizer is achieved, and plant diseases and insect pests spread through soil are relieved.
