Embodiment 1
[0014] Preparation of artemisinin mother liquor
[0015] Add the crude drug of Artemisia annua to No. 6 gasoline for extraction, put the extract on a silica gel column, recover the solvent from the effluent to obtain mother liquor A; add an eluent (petroleum ether: ethyl acetate = 95:5) to the silica gel column to elute until the Artemisia annua The eluent is eluted completely, the eluent is concentrated and crystallized, the crystallization solution is filtered to obtain the filtrate and the artemisinin recrystallization product, the solvent is recovered from the filtrate to obtain the mother liquor B, and the mother liquor A and the mother liquor B are combined to obtain the artemisinin mother liquor.
Embodiment 2
[0017] The test of Artemisia annua oil killing HIV: Artemisia annua oil and HIV virus (TCID 50 =1.78×10 5 After co-incubating for 1 hour, the HIV-1 P24 kit of Biomerieux was used to measure the amount of antigen P24, thereby deducing the amount of HIV virus. Inhibition rate=100×(1-measured OD value / HIV virus liquid control).
[0018] Artemisia annua oil has activity of killing HIV in vitro
[0019] The test of Artemisia annua oil directly killing HIV in vitro shows that Artemisia annua oil has a certain direct killing effect on HIV virus. When the concentration is 0.10mg / ml, the direct killing rate of HIV virus has reached more than 73%. The inhibitory effect is more obvious, as shown in Table 1.

Embodiment 3
[0024] Artemisia annua oil inhibits HIV-1 reverse transcriptase activity in vitro: add reverse transcriptase standard solution to the drug solution, and then use the Retrosys reverse transcriptase activity test kit from Innovagen Company to measure. Inhibition rate = 100 × (1 - measured OD value / positive control).
[0025] The test of Artemisia annua oil inhibiting the reverse transcriptase activity of HIV-1 in vitro shows that Artemisia annua oil has an inhibitory effect on the reverse transcriptase of HIV-1. The inhibition of recording enzyme reached 75.05%, see Table 2.
