Embodiment 1

[0037] Embodiment 1: the preparation of compound

[0038] Throat hair samples come from Yulong Snow Mountain in Lijiang, Yunnan. Sampling 2.0 kg of dried trichomes was crushed to 35 mesh, extracted 5 times with 95wt% methanol for 30 hours each time, combined the extracts, filtered, concentrated under reduced pressure to obtain 108 g of extract. The extract is dissolved in pure methanol with a weight ratio of 2.0 times, and then mixed with 130 g of 100-mesh silica gel, and 0.8 kg of 160-mesh silica gel is packed into a column for silica gel column chromatography. The volume ratio is 1:0, 20:1, 9:1, 8:2, 7:3, 6:4, 1:1, 1:2 chloroform-acetone gradient elution, TLC monitoring and merging the same parts to obtain 8 parts, wherein the volume ratio is 7: The chloroform-acetone eluted part of 3 was separated by Agilent 1100 semi-preparative high-performance liquid chromatography, with 48wt% methanol as mobile phase, Zorbax SB-C18 (21.2×250mm, 5 μm) preparative column as stationary ph...
