Embodiment Construction

[0018] As stated in the description, the present invention has a small limitation on the test parameters, and only one example is provided below. For matters not described in detail in the examples, refer to the conventional techniques in the field of Chinese medicinal chemistry.

[0019] The method for extracting perilla leaf extract from perilla leaf, comprises the following steps:

[0020] Take 100 g of perilla leaves, soak them in 1 L of solution for 10 h, wash them, and dry them. The solute of the solution consists of the following components: 13 mmol of HCl, 8 mmol of NaCl, 2 mmol of NH 4 h 2 PO 4 , 1.5mmol of H 3 BO 3 , 0.6 mmol of citric acid.

[0021] Crush to a diameter of less than 5mm, add 1% HCl-70% ethanol 160g, let it stand for 1h, after 25KHz, 300W ultrasonic treatment for 40min, extract 100g of the upper liquid, after purification by macroporous resin, extract 4g of active ingredient A.

[0022] Collect the remaining perilla leaves, dry them to 120g, add...

Abstract

The invention discloses a perilla leaf extract and an extraction method thereof. The perilla leaf extract comprises 1 part of active ingredient A extracted first and 1.25 parts of active ingredient B extracted for the second time, in parts by weight. After the ingredient A is extracted, polyphenols and anthocyanin in the perilla leaves are removed by use of a microwave method. The ratio of the ingredients of the perilla leaf extract is close to that of oils of the perilla leaves; especially, the ratio of perillaldehyde and the ratio of perillene are relatively high.

Description

technical field [0001] The invention relates to a perilla leaf extract and its extraction method, belonging to the chemical extraction process of plants. Background technique [0002] The main components of perilla leaf extract are perillaldehyde, pinene and limonene, etc., which can be used to prepare cosmetics, toothpaste and food flavors. 01107031.5 relates to a method for extracting perilla leaf extract from perilla seeds, including screening and removing impurities, raw material dehydration, pressing, filtering, degumming, deacidification, desoaping, washing and disinfection, crude oil dehydration, sterilization, cooling and other steps, degumming, The processes of deacidification, desoaping and dehydration are all carried out at room temperature between 40-60°C. The prior art also provides some methods for extracting perilla leaf extract from perilla leaves. "Optimized Microwave Extraction of Polyphenols from Perilla Leaves by Response Surface Method" (Wang Gennv) di...
