Embodiment 1

[0213] Example 1 An active extract derived from the non-medicinal parts of rhubarb, the extract refers to the rhubarb stems and petioles that were first picked in May to August, removed the rotted leaves and flocs, and cut the stems in half, Dry in the shade to obtain dry rhubarb stems and petioles; then cut the dried rhubarb stems and petioles into sections and put them into a pulverizer to pulverize them, pass through a No. 4 sieve to obtain rhubarb powder; finally, take 0.5 Kg of rhubarb powder and put it into a decoction bag. Put it into a multifunctional dynamic extraction tank, add 16 times the amount of water, heat and reflux for extraction, at a temperature of 100°C, decoct for 1.5 h, decoct for 3 times, filter and combine the filtrates for 3 times, at a temperature of 60°C and a pressure of 0.07MPa Concentrate under reduced pressure to an extract, then pack the extract into freeze-drying bottles, and freeze-dry it at a temperature of -45°C and a vacuum of 0.16mbar.

Abstract

The invention relates to an active extract derived from non-medicinal parts of rhubarb. The extract is made by firstly plucking stems and petiole of rhubarb from May to August, removing rotted leavesand inflorescences, splitting the stems half and half, and drying the split stems in shade to obtain dried rhubarb stems and petiole; then, sectioning the dried rhubarb stems and petiole, performing pulverization, and sieving the obtained product through a No.4 sieve to obtain rhubarb powder; and finally performing heating reflux extraction, pressure reduction concentration, and freeze drying to the rhubarb powder to obtain the active extract. The invention further discloses an application of the extract. The side effect of the active extract is obviously reduced.
