Embodiment 1

[0030] Embodiment 1: Accurately weigh 30g of blue water lily petal powder. Put it in a 1L flask, soak the petal powder with 600mL 5% NaCl solution, let it soak for 4 hours, install it on the left end of the simultaneous distillation extraction device, and heat it with an electric heating mantle until it boils; put 100mL of dichloromethane into a 500mL flask , connected to the right end of the simultaneous distillation and extraction device, and heated to 50°C with a constant temperature water bath to make it boil. After distilling and extracting for 2 hours at the same time, the flask with dichloromethane at the right end was removed, anhydrous sodium sulfate was added for drying, and the organic reagent was removed by rotary evaporation to obtain the essential oil product with a calculated yield of 0.10%.

Embodiment 2

[0031] Embodiment 2: Accurately weigh 30g of blue water lily petal powder. Put it in a 1L flask, soak the petal powder with 600mL10% NaCl solution, let it soak for 4 hours, install it on the left end of the simultaneous distillation extraction device, and heat it with an electric heating mantle until it boils; put 100mL of dichloromethane into a 500mL flask, Connect to the right end of the simultaneous distillation and extraction device, and heat it to 50°C with a constant temperature water bath to make it boil. At the same time, after distillation and extraction for 2 hours, the right end of the flask containing dichloromethane was removed, anhydrous sodium sulfate was added for drying, and the organic reagent was removed by rotary evaporation to obtain an essential oil product with a calculated yield of 0.14%.

Embodiment 3

[0032] Embodiment 3: Accurately weigh 30g of blue water lily petal powder, place it in a 1L flask, soak the petal powder with 600mL10% NaCl solution, let it soak for 4h, install it on the left end of the simultaneous distillation extraction device, and heat it to its peak with an electric heating mantle Boiling; put 100mL of dichloromethane into a 500mL flask, connect it to the right end of the simultaneous distillation and extraction device, and heat it to 50°C with a constant temperature water bath to make it boil. At the same time, after distillation and extraction for 4 hours, the right end of the flask containing dichloromethane was removed, anhydrous sodium sulfate was added for drying, and the organic reagent was removed by rotary evaporation to obtain an essential oil product with a calculated yield of 0.16%.

Abstract

The invention belongs to the technical field of recycling or refining of essential oil from raw materials, and discloses an extraction method and applications of nymphaea tetragona essential oil. According to the extraction method, steam distillation and solvent extraction are combined through a simple method, condensation and separation of fragrant components are combined, experimental steps arereduced, operation is simple, qualitative and quantitative effects are excellent; thousands of folds of condensation of trace components can be realized using a small amount of solvents, extraction rate on fragrant components is relatively high, and adverse influences caused by long term high temperature heating are avoided. Nymphaea tetragona petals are taken as raw materials, simultaneous distillation and solvent extraction (SDE) is adopted for extraction of essential oil, and GC-MS is adopted for identification of the main chemical components in essential oil, and preliminary research on the in vitro anti-oxidation performance of essential oil is carried out.

Description

technical field [0001] The invention belongs to the technical field of recovering or refining essential oil from raw materials, and in particular relates to an extraction method of blue water lily essential oil and its application. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: Nymphaea is a perennial aquatic herb of the family Nymphaeaceae, which is widely planted in temperate and tropical regions. The water lily can be viewed and admired, and the rhizome can be cooked. Modern studies have shown that Nymphaea plants contain various types of compounds, such as flavonoids, polysaccharides and alkaloids. More than 70 flavonoids and phenolic acid compounds were isolated from Nymphaea plants, namely flavonoids, flavonols and isoflavones. Nymphaea candida has a long history of medicinal use among the people. Among them, Nymphaea candida is a traditional medicinal material of the Uygur people in my country. Its ...
