100 results about "Elemene" patented technology

Elemenes are a group of closely related natural chemical compounds found in a variety of plants. The elemenes, which include α-, β-, γ-, and δ-elemene, are structural isomers of each other and are classified as sesquiterpenes. The elemenes contribute to the floral aromas of some plants, and are used as pheromones by some insects.

Beta-elemene amino acid or carboxylic acid derivatives and preparation process and use thereof

The invention discloses a A-elemene amino acid or carboxylic acid derivants, Process for preparing, usage and preparation; the structural formula of derivant is III. Wherein R represent C2-C20 every kinds of alpha-, beta-, gamma- amino acids; Every kinds of amino acids of C1-C20; wherein cyclohexane skeleton has three chirality center. This derivant is used to improve water-solubility and anticancer active of A-elemene amino acid, introducing amino acid which contains synthetic compounds of amidol or carboxy group, this derivant has stronger physiologically active and larger polarity, reaching the purpose of improving water-solubility.

Preparation method and applications for polydopamine coated mesoporous silica/elemene composite nanoparticle preparation

The invention discloses a preparation method and applications for a polydopamine coated mesoporous silica/elemene composite nanoparticle preparation. The preparation method includes dropwise adding anelemene and ethanol mixed solution into a mixed solution of mesoporous silica and deionized water under room temperature, performing centrifugation for 3 min after performing stirring for 4 h, and removing supernatant to obtain mesoporous silica/elemene composite nanoparticles; dropwise adding a mixed solution of the composite nanoparticles and the deionized water into a Tris buffer solution containing dopamine salt, performing stirring for 12 h at the room temperature, performing centrifugation for 3 min, and performing washing for 3 times with the deionized water; and obtaining polydopaminecoated mesoporous silica/elemene composite nanoparticles. The method can prepare polydopamine coated mesoporous silica/elemene nano-composite materials with different mass fractions. Through the showing of solid ultraviolet test results, good ultraviolet absorption can be achieved after polydopamine coats mesoporous silica/elemene nanoparticles, so that the nano preparation cannot be easily swallowed by a reticuloendothelial system and has good sustained release effects.

Use of beta-elemene and derivatives thereof in preventing atherosclerosis

The invention relates to the field of natural medicines, and particularly relates to use of beta-elemene and derivatives thereof in preventing atherosclerosis, and in particular relates to an application in preparation of medicines for treating atherosclerosis. Test results show that beta-elemene and derivatives can remarkably reduce the atherosclerotic plaque area in the coronary artery of an animal model, and meanwhile has remarkable improving effect on two key links in development process of atherosclerosis: adhesion of leukocyte and endothelial cells and peroxidation of lipids. Expression of adherence factors closely related to atherosclerosis can be reduced, so that peroxidation damage of endothelial cells in vitro and in vivo caused by high fat and H2O2 is avoided.

Method for extracting delta-elemene

The invention provides a method for extracting delta-elemene. The method comprises the following steps of: (1) carrying out ordinary rectification by using zedoary turmeric oil of which the delta-elemene content is more than 1.5% as the raw material, wherein the vacuum degree inside a rectifying column is 150-300Pa and the rectification ratio is 2:1, and collecting distillate with a temperature of 128-135 DEG C; (2) carrying out primary fine rectification by using the distillate obtained in the step (1) as the raw material, subsequently carrying out the secondary fine rectification by using the obtained distillate as the raw material, wherein the rectification ratios are different (4:1 in the primary fine rectification, and 6:1 in the secondary fine rectification) and the vacuum degrees in precise rectifying columns are both set as 50-150Pa, and collecting distillate with a temperature of 120-125 DEG C; and (3) carrying out axial compression high pressure column separation by using the obtained distillate in the step (2) as the raw material. According to the method, a method of primary ordinary rectification, secondary precise rectification and axial compression high pressure column separation is utilized, delta-elemene with high purity is obtained, and the difficult problem that no reference substances of the delta-elemene are available for years is solved.
