Artemisinin is the first-line drug for anti-malaria recommended by the World Health Organization (WHO). As the sole natural plant source of artemisinin, ecotypes of Artemisia annua L. vary widely in artemisinin content between nations, and China is the main producing area of A. annua. Here we present a three-dimensional evaluation on ecotypic diversity of A. annua from 12 main producing areas i...
BACKGROUND In addition to recognized antimalarial effects, Artemisia annua L. (Qinghao) possesses anticancer properties. The underlying mechanisms of this activity are unknown. The aim of our experiments was to investigate the effects of distinct types of compounds isolated from A. annua on the immune-activated production of major mediators of angiogenesis playing a crucial role in growth of tu...
Haemonchus contortus is a blood-sucking abomasal parasite of small ruminants that is responsible for major losses to producers worldwide. Resistance of this nematode to commercial anthelmintics has produced a demand for alternative control methods. Plants in the genus Artemisia have traditionally been used as anthelmintics and whole plants and plant extracts have demonstrated activity against g...
Objective: This review intends to motivate and encourage researchers to explore new alternatives to treat different diseases with Artemisia annua L., an important plant of traditional Chinese pharmacopoeia that has been used for more than 2.000 years in the treatment of different diseases, mainly malaria. Methods: Data include currently available information about A. annua, its origin, traditio...
Artemisinin is the active antimalarial compound obtained from the leaves of Artemisia annua L. Artemisinin, and its semi-synthetic derivatives, are the main drugs used to treat multi-drug-resistant Plasmodium falciparum (one of the human malaria parasite species). The in vitro susceptibility of P. falciparum K1 and 3d7 strains and field isolates from the state of Amazonas, Brazil, to A. annua i...
در این تحقیق اثر کودهای شیمیایی ازت و فسفر بر میزان رشد، کیفیت و کمیت اسانس در گیاه درمنه شیرین (artemisia annua l.) مطالعه شد. برای این منظور اثر کودهای نیتروژن (46% به فرم اوره) و فسفر (48% به فرم سوپر فسفات تریپل) هر کدام در چهار سطح به مقادیر صفر، 40، 80 و 120 کیلوگرم در هکتار روی رشد رویشی و تغییرات کمی و کیفی اسانس برگ درمنه شیرین بررسی شد. این آزمایش به صورت بلوکهای کامل تصادفی، با 16 تی...
Artemisinin, a sesquiterpenoid endoperoxide, isolated from the plant Artemisia annua L., is widely used in the treatment of malaria. Another sesquiterpenoid, β-caryophyllene having antibiotic, antioxidant, anticarcinogenic and local anesthetic activities, is also presented in A. annua. The role played by sesquiterpene transporters in trichomes and accumulation of these metabolites is poorly und...
