Embodiment 1

[0054] Example 1 In vitro safety of rhododendron extract

[0055] 1.1. Experimental materials

[0056] Rhododendron japonica extract, DMEM cell culture medium, PBS buffer, skin fibroblast L929, skin stratum corneum cells HaCaT, MTT, 96-well plate

[0057] 1.2. Experimental Instruments

[0058] Stereo Microscope, Microplate Reader

[0059] 1.3. Experimental steps

[0060] The cells (skin fibroblasts L929 and skin stratum corneum cells HaCaT) were planted in 96-well plates respectively, and when the cell plating degree reached 60-70%, the medium was removed and replaced with the medium containing and not containing Rhododendron japonica extract. Fresh medium, continue to cultivate for 24 hours, then remove the medium and replace it with medium containing 0.5mg / ml MTT, after 4 hours of culture, use a microplate reader to detect the absorbance at 490nm, and process the results to make a histogram.

Abstract

The invention belongs to the technical field of daily chemical industry, and specifically provides a plateau rhododendron extract and its use for protecting ultraviolet damage and sports care. The plateau rhododendron grows at an altitude of 2800-4500 meters, and the plateau rhododendron extract is the extract of plateau rhododendron Flower and leaf extracts. The plateau rhododendron extract provided by the invention can alleviate the damage of ultraviolet radiation to the body and the inflammation caused by long-term strenuous exercise, and can prevent the damage of ultraviolet radiation in outdoor sports. The plateau rhododendron extract has no obvious toxic and side effects, and at the same time has the functions of protecting ultraviolet radiation damage and alleviating exercise fatigue.

Description

technical field [0001] The invention belongs to the technical field of daily chemicals, and in particular relates to the use of plateau rhododendron extracts for ultraviolet damage protection and sports care. Background technique [0002] On the Qinghai-Tibet Plateau, rhododendron (scientific name: Rhododendron simsii Planch) is one of the main shrubs, with more than 10 species. Tibetan medicine classifies rhododendrons into white rhododendrons and black rhododendrons according to their flowers. They have different titles in the folk. They are used internally to treat chronic bronchitis and externally for anti-inflammatory swelling due to their functions of clearing away heat, relieving cough, relieving asthma, eliminating phlegm, and reducing inflammation. And widely used by the people. The flowers, leaves and twigs of Rhododendron are used as medicine in Tibetan medicine. Rhododendron has been included in the catalog of daily chemical raw materials. [0003] Plateau Rho...
