Embodiment 1

[0030] The preparation of the total phenols of embodiment 1 dragon's blood

[0031] Get dragon's blood raw material drug (Yunnan Xishuangbanna Yulin Pharmaceutical Co., Ltd. production, approval number: Z53021662) 1Kg, add 95% (v / v) ethanol to all dissolving, add distilled water until the alcohol content is 40% ( v / v), filter, get the supernatant, the precipitation part repeats the above-mentioned operation 3 times, and the supernatant merges; ) ethanol for elution, discard the eluent, elute with 80% (v / v) ethanol of 8 times the column volume, and recycle the solvent from the eluent to dryness to obtain 0.58Kg of total phenols of dragon's blood.

Embodiment 2

[0032] The preparation of embodiment 2 dragon's blood jerky total flavonoids

[0033] Take dracaena raw material drug (produced by Yunnan Xishuangbanna Yulin Pharmaceutical Co., Ltd., approval number: Z53021662) 1Kg, add 8 times the amount of ethyl acetate to reflux and extract twice, each time for 1 hour, filter, and combine twice Filtrate, reclaim ethyl acetate and concentrate to dryness; The ethyl acetate extract is pulverized into coarse powder, stirs 30 minutes with the 0.35% (v / v) NaOH solution of 30 times of extract amount to dissolve, filter; Filtrate with 10% ( v / v) Adjust the pH to 1-2 with HCl, let it stand for 12 hours, pour out the supernatant, and discard; the precipitate is centrifuged and filtered, and the precipitate is collected, washed with deionized water until the pH test paper detects it as neutral, below 60°C Vacuum-dried, pulverized, and passed through an 80-mesh sieve to obtain 0.50 kg of total flavonoids of dragon's blood.

Embodiment 3

[0034] Embodiment 3 Anti-radiation effect of dragon's blood drug prophylaxis

[0035] experimental method

[0036] Thirty-six Wistar rats (half male and half female) were randomly divided into two groups, namely the model control group (no radiation administration) and the administration group (radiation+administration). Before radiation, the administration group was given dracaena raw material drug (produced by Yunnan Xishuangbanna Yulin Pharmaceutical Co., Ltd., approval number: Z53021662) once a day by intragastric administration at a dose of 2 g / kg, and the model control group was given etc. The volume of the solvent control was administered continuously for 5 days. Carry out heavy ion radiation 2 hours after administration on the 6th day: the energy is 80MeV / u 12 C 6+ The ions were generated at the Lanzhou Heavy Ion Accelerator (HIRFL) at the Institute of Modern Physics, Chinese Academy of Sciences. After anesthetizing the rats, 12 C 6+ Ions were given a one-tim...
