Problems solved by technology

However, the technology relies on pure supercritical CO 2 The fluid extraction method is only limited to the extraction of the small molecular weight essential oil part, and the active ingredients of the large molecular weight water-soluble part are ignored; in addition, since Lingxiang is a plant of the Primula genus, the organic acids, Aromatic phenols, alcohols, aldehydes, ketones and their derivatives are contained in the intercellular and intercellular pectin between plants, and CN1414077A uses CO 2 In fluid extraction, raw materials are processed by pulverizing them first. However, such pulverized particles cannot damage cells very finely. Too fine powder not only consumes power energy, but also forms paste prizes that in turn block CO2. 2 fluid extraction
Therefore, there are incomplete extraction of active ingredients, and the extraction yield is lower than 2.0%.

Embodiment 1

[0030] 1) Extraction of active ingredients from Lingxiang

[0031] 600 kg of freshly collected Linglingxiang, washed away the sand, air-drained, aged for 3-4 hours, and dried with calcined soil; cut into 30-50mm long pieces and soaked in 200 kg of water for 2 hours. Then place it in a stainless steel container, add cellulase and pectinase to extract for 4 hours. Filtrate, collect the active ingredient extract in the separation liquid, and obtain 70 kg of water-soluble active ingredient extract product. Smoke the Lingxiang slag after enzymolysis with logs for 6-8 hours, or smoke with Lingxiang dry waste residue for 10-12 hours; remoisturize to obtain 85 kg of smoked and roasted Lingxiang slag; Lingxiang residue, using supercritical CO 2 The fluid is used as an extraction solvent for extraction, and the extract is subjected to high-speed centrifugation to obtain partial extracts of essential oils; supercritical CO 2 The extraction process conditions are: the extraction pressu...

Embodiment 2

[0035] 1) Extraction of active ingredients from Lingxiang

[0036] 500 kg of freshly collected Linglingxiang, washed off the sand, drained by air, aged for 4 hours, and dried with calcined clay; cut into 30mm long pieces and soaked in 100 kg of water for 2 hours. Then place it in a stainless steel container, add cellulase and pectinase to extract for 4 hours. Filtrate, collect the active ingredient extract in the separation liquid, obtain 61 kilograms of water-soluble active ingredient extract products. Smoke the Lingxiang slag after enzymolysis with logs for 6-8 hours, or smoke with Lingxiang dry waste residue for 10-12 hours; remoisturize to obtain 72 kg of smoked and roasted Lingxiang slag; Tonka residue, using ethanol as a polar solvent entrainer, using supercritical CO 2 The fluid is used as an extraction solvent for extraction, and the extract is subjected to high-speed centrifugation to obtain partial extracts of essential oils; supercritical CO 2 The extraction proc...

Abstract

The invention relates to a method for extracting effective constituents from holy basil. Newly-collected holy basil is used as raw materials, and water-soluble effective constituent extractive and essential oil part extractive are obtained through aging treatment, enzymolysis, resin adsorption, holy basil log smoke curing and essential oil extraction through supercritical fluid. An ancient folk technology and a modern leading-edge process are organically bonded in the method, the extracted effective constituents are free of residual solvents, aroma components are not damaged, the effective constituents are completely extracted, and extraction yield is high.

Description

technical field [0001] The invention relates to a method for extracting active ingredients of natural plants, in particular to a method for extracting active ingredients from Lingxiang. Background technique [0002] Linglingxiang, also known as Lingxiang (Lysimachia foenum-graecum Hance), is a plant of the genus Primulaceae, which is mainly produced in Jinxiu Yao Autonomous County of Guangxi Zhuang Autonomous Region and Jianghua Yao Autonomous County of Hunan Province. The name of Linglingxiang was first recorded in "Jiayou Materia Medica", which is the lavender in "Famous Doctors". Song "Tujing Materia Medica" contains: "Linglingxiang, which is found in all the lakes and ridges today, mostly grows in wetlands. The leaves are like hemp, facing each other, and the stems are like scorpions. They often bloom in mid-July. The most fragrant, the so-called smoked grass in ancient times, or cloud, the same with smoked grass." Lingxiang contains more organic acids and aromatic phe...
