Preparation method and application of Paeonia suffruticosa Andr. flower water

Abstract

The invention discloses a preparation method and application of Paeonia suffruticosa Andr. flower water. The method of preparing the Paeonia suffruticosa Andr. flower water provided by the invention comprises the following steps of (1) taking Paeonia suffruticosa Andr. buds with the diameter of 1.5-2.5 centimeters from a big windbell period to a blooming period, and cleaning petals without stamens with purified water to obtain cleaned Paeonia suffruticosa Andr. petals; and (2) distilling the Paeonia suffruticosa Andr. petals cleaned in the step (1) according to the ratio of the fresh weight of the petals to the weight of the purified water of 1 to 1-1 to3 for 1-3 hours, and collecting clear and transparent liquid condensed after distillation so as to obtain the Paeonia suffruticosa Andr. flower water. According to the preparation method and the application of the Paeonia suffruticosa Andr. flower water, the Paeonia suffruticosa Andr. flower water obtained by distilling the petals of Paeonia suffruticosa Andr. buds contains a large number of functional components, and the value of the Paeonia suffruticosa Andr. flower water is fully exerted when the Paeonia suffruticosa Andr. flower water is used in the fields of skin care and food.

Description

technical field [0001] The invention relates to an extraction method, in particular to a preparation method and application of peony flower water. Background technique [0002] Peony (Paeonia suffruticosa Andr.) is a perennial deciduous shrub of Paeoniaceae (Paeoniaceae), native to China, and has a history of artificial cultivation in my country for more than 1600 years. It is an important resource integrating ornamental, medicinal and edible. plant. In 2011, the seed oils of Fengdan and Purple Spotted Peony were approved as new resource foods, and in 2013, the petals of 'Fengdan' peony were approved as new resource food raw materials, which expanded its scope of application. At present, researches on flowers as materials mainly focus on pigment composition, content, coloring mechanism and antioxidant activity of petal extracts. The compounds isolated and identified mainly include flavonoids, flavonols and anthocyanins. In addition, fatty acids, polysaccharides, Protein, po...

Problems solved by technology

[0003] The above studies focused on secondary metabolites such as flavonoids for peony flowers in full bloom, which laid the foundation for the development and utilization of petals. However, there is a lack of research on the accumulation of small molecule volatiles during the development of peony flowers and the technology of petal distillation.

Especially in recent years, the popularity of peony stamen tea, the unopened flower buds are the best raw material for picking stamens, followed by the petals becoming waste after picking, resulting in a great waste of resources

So far, the pure dew obtained by distillation of peony petals is relative content (peak area method, the value is %), and the absolute content is unknown, which is not conducive to accurate addition as later raw materials

[0004] There have been studies on the content analysis of flavonoid compounds in the petals, and the volatile components in the blooming stage of the flower, but the research on the synthesis and accumulation of the volatile components in the petals at different development stages has not been reported so far; The headspace collection method and relative quantitative method are often used in the determination of volatile components in time (Li SS, Chen LG, XuYJ, Wang LJ, Wang LS. 2012. Identification of floral fragrances in tree peonycultivars by gaschromatography–mass spectrometry. Scientia Horticulturae, 142 :158–165), which detected a total of 58 volatile components by GC-MS from the full-flowering stage of 'Fengdan' and calculated the percentage content. From the perspective of proportion, the determined compounds in the full-flowering stage are mainly It is terpenes, alkanes and alcohols, etc., accounting for 47.531%, 0.638%, and 14.491% of the total volatile components, respectively
