53 results about "Delphinidin" patented technology

Delphinidin (also delphinidine) is an anthocyanidin, a primary plant pigment, and also an antioxidant. Delphinidin gives blue hues to flowers in the genera Viola and Delphinium. It also gives the blue-red color of the grape that produces Cabernet Sauvignon, and can be found in cranberries and Concord grapes as well as pomegranates, and bilberries.

Method for separating and preparing five high-purity anthocyanidin monomers from grape skins

The invention discloses a method for separating and preparing five high-purity anthocyanidin monomers from grape skins, relating to the preparation of natural pigments and belonging to the fields of food safety and food analytic chemistry. The method comprises the following steps of: firstly, carrying out anthocyanidin digestion on carbernet sauvignon grape skins to obtain crude extractive of anthocyanidin; then purifying the crude extractive by using XAD-7HP macroporous resin, and removing most of moisture absorption components such as saccharides, inorganic salts, phlegmatic temperament and the like in the crude extractive; and carrying out preparative liquid phase separation on the extractive of anthocyanidin subjected to the preliminary purification to obtain the high-purity monomers of the anthocyanidin. The method has the advantages of only using alcohol and acid as a solvent in stages of extraction, purification and separation in the preparation of the anthocyanidin and being environment-friendly, simple, convenient and feasible. The five anthocyanidin monomers obtained after purification are respectively delphinidin glucoside, 3'-methyl delphinidin glucoside, dimethyl delphinidin glucoside, dimethyl delphinidin acetylation glucoside, and dimethyl delphinidin trans-tonka-bean acetylation glucoside, the purities of which are sequentially 99.9%, 99.9%, 99.9%, 99.9%, 91.7%, 95.5%.

Antiseptic swill water fertilizer

Provided is an antiseptic swill water fertilizer. Swill is kitchen garbage of restaurants, canteens and families, and quick lime powder, nandina domestica powder, oleander powder, delphinium grandiflorum powder, crinum asiaticum powder, castor powder, poinsettia powder and the like are added into the swill. Crops such as growing vegetables and flowers can be watered with the swill mixed solution, pests can be killed. The swill mixed solution is good in insecticidal effect, the growth condition of plants irrigated by the swill mixed solution is good, the growth of the plants can be promoted, and the swill mixed solution is pollution-free and non-toxic, and plays an important role in protecting the environment. The swill plays an important role in killing and controlling insects, and the mixed solution obtained by adding quick lime powder, nandina domestica powder, oleander powder, delphinidin powder, crinum asiaticum powder, castor powder and poinsettia powder into the swill has a very good insect killing effect. The Antiseptic swill water fertilizer prepared by the invention not only can play a role in preventing and controlling insects and reducing environmental pollution, but also can be used for irrigating plants such as vegetables, fruit trees and flowers as a fertilizer to promote the growth of the plants.

InactiveCN108484701ASolve unstable puzzlesExcellent Matrix GuaranteeSugar derivativesSugar derivatives preparationBiotechnologyChromatographic separation
The invention provides a method for preparing tea tree purple bud anthocyanin high-purity products through separation. The method comprises the following steps: extracting tea tree purple buds by an acidic ethanol solution, performing extraction to defat, performing strong acid type action exchange resin separation to remove impurities, performing high-speed countercurrent chromatographic separation to obtain anthocyanin refined products, and performing purification by preparation type high performance liquid chromatography to obtain five anthocyanin high-purity products. According to the method, the fresh leaves of the purple bud tea tree varieties (Zijuan, red bud fingered citron, An 73 and optional 9803) rich in anthocyanin as raw materials and multi-stage separation and purification process technologies are creatively applied; meanwhile, the five tea tree purple bud anthocyanin high-purity products with single anthocyanin purity being more than 90 percent are prepared, wherein thepurity of delphinidin-3-O-(6-(E)p-coumaric acid)pyran galactoside exceeds 98 percent and the monomer quality requirement is met. The whole production process is simple, low in production cost and highin operability; high-quality raw materials are provided for research on pharmacology and medical efficacy and development of functional terminal products; furthermore, high-value utilization of the tea tree purple bud resources is realized truly.
