Embodiment 1
[0075] Embodiment 1: the preparation of extract
[0076] Get 10g of Tianshan Snow Lotus from Tianshan Snow Lotus Farm in Xinjiang Tianshan, grind it into powder, and pass No. 3 sieve. Ultrasonic extraction was performed with water (400 mL) 40 times the weight of Saussurea tianshanensis for 30 minutes; after centrifugation at 5000×g for 10 minutes, the supernatant was collected; the above steps were repeated. After collecting the supernatant twice, add water to make the volume to 0.010 g crude drug / ml (that is, to make the volume to 1 L) to obtain the Saussurea tianshanensis extract.
[0077] Take 10g of Indonesian house white bird's nest, soak the bird's nest at room temperature for 3 hours with 100 times the weight of water (1L), filter to obtain the bird's nest filter residue; stew the bird's nest filter residue with 30 times the weight of bird's nest water (300mL) for 6 hours; filter to remove the stewed Add water to the boiled bird's nest residue to a volume of 0.010 g cr...
Embodiment 2
[0078] Embodiment 2: antioxidant effect test
[0079] A standard curve was established based on the copper ion oxidation resistance of TROLOX (an analogue of vitamin E), and the total antioxidant capacity of different bird's nest extracts and Saussurea tianshanensis extracts was calculated according to the standard curve. In this test, the higher the TROLOX equivalent, the better the antioxidant capacity of the tested extract (see figure 2 ).
Embodiment 3
[0080] Embodiment 3: the synergistic effect of Tianshan Snow Lotus Extract and Bird's Nest Extract
[0081] This example shows the synergistic effect of Tianshan Snow Lotus extract and bird's nest extract on antioxidant capacity.
[0082] Weigh the Saussurea esculenta extract, the bird's nest extract prepared according to Example 1, and the compositions in which the weight ratios of the Saussurea chinensis extract and the bird's nest extract are 1:1, 3:1 and 5:1. Antioxidant capacity tests were performed in the following experimental groups to compare the effect of the composition relative to the individual components.
[0083] Control group: take water without adding any test substance as the blank control
[0084] Group 1: 1:1 group
[0085] a: the composition of 12 parts by weight (i.e. 1 gram) of Saussurea tianshanensis extract and 12 parts by weight (i.e. 1 gram) of bird's nest extract
[0086] b: 12 parts by weight (i.e. 1 gram) of Saussurea tianshanensis extract and ...
