How is artemisinin produced?
Artemisinin is naturally produced in trichomes of leaves. At the same time, transgenic hairy roots are considered a good source to harvest artemisinin. However, the absence of trichomes in hairy roots suggests that artemisinin biosynthesis is not limited to trichomes.
How do you extract artemisinin?
Artemisinin extraction was performed by immersing 0.1 g of sieved dry leaves to 10 mL of n-hexane, resulting in a plant material to solvent ratio of 1:100 to prevent solvent saturation. The extraction was performed at 69 °C for 1 h.
What is precursor for artemisinin?
Using synthetic biology, the metabolism of the microbe is engineered to produce artemisinic acid, a precursor to artemisinin. Starting from acetyl-CoA (an abundant product of the central metabolism (more…)
What is the mechanism of action of artemisinin?
Artemisinin is believed to act via a two-step mechanism. Artemisinin is first activated by intraparasitic heme-iron which catalyzes the cleavage of this endoperoxide. A resulting free radical intermediate may then kill the parasite by alkylating and poisoning one or more essential malarial protein(s).
How much artemisinin should I take?
The conventional dosage regimen for orally administered Artemisinin is 500-1000 mg (10-20 mg/kg) on the first day, followed by 500 mg daily for 4 days.
What is the difference between Artemisia and artemisinin?
is that artemisia is (plant) any of many aromatic flowering plants of the genus artemisia , including wormwood, sagebrush, and tarragon while artemisinin is (medicine|biochemistry|organic compound) an antimalarial drug derived from the (sweet wormwood) shrub, , found as the active ingredient in traditional chinese …
Which mobile phase is used in artemisinin drug?
Analysis of artemisinin was achieved by UPLC using a Waters Acquity UPLC™ system fitted with a single quadrupole (SQ) detector (Waters Corporation, Milford, MA). The mobile phase was an isocratic system consisting of 60% v/v aqueous solution of 0.1% formic acid and 40% v/v acetonitrile.
Which mobile phase is isolated the artemisinin?
Chromatographic separation of artemisinin from plant extract was performed over silica gel 60 F254 HPTLC plate using n-hexane : ethyl acetate as mobile phase in the ratio of 75 : 25, v/v. The plate was developed at room temperature 25 ± 2.0°C.

- skin rash.
- nausea.
- vomiting.
- tremors.
- liver issues.
