Embodiment 1

[0027] A dendrobium officinale flower extract with whitening effect is characterized in that: the following raw materials are composed of 80% of dendrobium officinale flower element and 20% of rice bran oil in parts by mass.

[0028] The dendrobium officinale flower element is obtained by flash extraction technology combined with subcritical extraction method, and the steps are as follows:

[0029] (1) Flash extraction: Add the chopped fresh petals of Dendrobium candidum into the flash extractor, and add 95% (volume ratio) ethanol with 10 times the mass weight;

[0030] (2) The mixture in step (1) was turned at 6000 rpm, the extraction time was 3 minutes, and the extraction temperature was 20°C.

[0031] (3) Centrifuge the mixture in step (2) at high speed to obtain an ethanol extract.

[0032] (4) Concentrating the ethanol extract in step (3) by vacuum heating to an ethanol-free extract.

[0033] (5) Subcritical extraction: put the extract in step (4) into a closed extracti...

Abstract

A dendrobium candidum flower extract with a whitening effect comprises, by weight, 80-90% of dendrobium candidum florigen and 10-20% of rice bran oil, wherein the dendrobium candidum florigen is prepared by flash extraction technology and a sub-critical extraction method. The dendrobium candidum flower extract has the advantages that a preparation process is low in cost and high in production efficiency, the problem of easiness in browning in the production process is solved by combining flash extraction with sub-critical extraction technology, and the fat-soluble dendrobium candidum flower extract achieves the multilayer whitening effect by improving skin microcirculation, inhibiting black pigment formation, resisting oxidation and improving skin colors.

Description

technical field [0001] The invention relates to the technical field of deep processing of traditional Chinese medicinal materials, in particular to a dendrobium officinale flower extract with whitening effect. Background technique [0002] Dendrobium candidum, also known as Wanzhangxu, is listed in "Shen Nong's Materia Medica" and is listed as top grade. As a perennial herb, Dendrobium grows in tropical and subtropical virgin forests and similar warm and humid environments, mostly epiphytic on large tree trunks or rocks. It has good effects in anti-tumor, improving human immunity, treating gastrointestinal diseases, anti-aging, anti-oxidation, anti-platelet aggregation, lowering blood sugar and treating cataracts. [0003] The flowers of Dendrobium officinale are the flowers of Dendrobium officinale. It is the most luxuriant and beautiful from May to July. The flower of Dendrobium officinale is light yellow, with six petals in total. The most significant effect is to relie...
