Embodiment Construction

[0016] The related technical problems of the present invention will be further described in detail below. The applicant compared the yield of the perilla flavonoid extract extracted by the method of the present invention with the perilla flavone extract extracted directly with ethanol solvent without membrane breaking treatment, and the flavonoid content was measured by ultraviolet spectrophotometry.

[0017] 1. Preparation of standard curve

[0018] Accurately weigh 0.0501g of rutin standard substance, dissolve it with 30% ethanol, and completely transfer it into a 500ml volumetric flask, and dilute to volume with 30% ethanol. Take rutin standard solution 0, 1, 2, 4, 6, 8, 10ml respectively in seven 25ml volumetric flasks, supplement to 15ml with 30% ethanol, add 0.7ml of 5% sodium nitrite, shake well, and place for 5min Then add 0.7ml of 10% aluminum nitrate, and then add 5ml of 4% sodium hydroxide after 6 minutes, mix well, dilute to the mark with 30% ethanol, measure colo...

Abstract

The invention discloses a natural antioxidant of perilla flavone for cigarette and a method for preparing the same, and relates to the technical field of additives for cigarettes. The natural antioxidant of perilla flavone for cigarette is prepared by the following steps that: the residue obtained after the naphtha is extracted from perilla leaves is dried, subjected to vacuum film breaking, soaking, compound enzyme-catalysis, namely ethanol refluxing extraction, pressure reduction suction filter and low-temperature high-speed centrifugation and refined to obtain an extracting solution of perilla flavone. The method for preparing the natural antioxidant of perilla flavone for cigarette comprises the following steps: (1) raw material processing, and vacuum film breaking; (2) soaking, and adding 0.1 to 1 percent compound enzyme; and (3) extraction and refining. When the extract of the invention is added to the cut tobacco, the quality of the cut tobacco is not changed. The raw material used by the invention is wide in source and low in cost and price; and the method has the advantages of simple technological process and simple equipment, and the extract can be used as a novel natural antioxidant for cigarette.

Description

technical field [0001] The invention relates to the technical field of tobacco additives, in particular to an extraction and preparation method of natural tobacco antioxidant-perilla flavone. Background technique [0002] In tobacco products, it is necessary to ensure the quality of smoke and the low hazard of cigarettes. Adding tobacco additives-antioxidants to cigarettes has attracted more and more attention. Extracting natural antioxidants for tobacco use is an important direction for harm reduction and tar reduction, and the applicant is exploring along this direction. [0003] Perilla leaves are the leaves of Perilla frutescens (L.) Britt., a plant of the Labiatae family, also known as perilla leaves, which have the function of detoxification and are annual herbaceous plants. Originally produced in China, it is now mainly distributed in countries such as India, Myanmar, China, Japan, North Korea, South Korea, Indonesia and Russia. There are wild species and cultivated...
