1. ARTEMISININA E DERIVADOS: DESCOBERTA, ESTRATÉGIAS SINTÉTICAS E OBTENÇÃO INDUSTRIAL
Artemisinin, a natural sesquiterpene isolated from the Artemisia annua L. plant, represents a remarkable achievement in the treatment against malaria. Since its discovery in the 1970’s, researchers readily started synthesizing this complex natural product containing an unusual endoperoxide fragment. Despite various total syntheses reported, only in the las

2. Influence of Artemisia Annua on Broiler Performance and Intestinal Microflora
ABSTRACT The present study aimed to investigate the effect of Artemisia (Artemisia annua) supplementation as essential oil and powder, in broiler diet on performance and intestinal microflora. One hundred and eighty Cobb 500 broiler chicks assigned to three experimental groups (six replicates with 10 broilers per replicate) were housed in an environment-cont

3. Comparison of the Dietary Supplementation of Lactobacillus plantarum, and Fermented and Non-Fermented Artemisia Annua on the Performance, Egg Quality, Serum Cholesterol, and Eggyolk-Oxidative Stability During Storage in Laying Hens
ABSTRACT Artemisia annua L. is a widely distributed medicinal plant and well-known for treating malaria due to the artemisinin content. We previously found enhanced antioxidant and antibacterial activities of Lactobacillus plantarum-fermented A. annua dried leaves in vitro. The present study compared the effects of the dietary supplementation of L. plantarum

4. Characterization of hepatoprotective metabolites from Artemisia annua and Cleome droserifolia using HPLC/PDA/ESI/MS–MS
ABSTRACT The hepatoprotective activities of two traditionally used plants, Cleome droserifolia (Forssk.) Delile, Cleomaceae, and Artemisia annua L., Asteraceae, were recently reported. However, the biologically active metabolites responsible for this activity were not identified. The aqueous extract of C. droserifolia aerial parts, and the polar fraction of

5. Bioactivity of essential oils from Artemisia against Diaphania hyalinata and its selectivity to beneficial insects
ABSTRACT: The demand for effective insecticides in pest control with low toxicity to the non-target organisms, such as natural enemies and pollinators, is increasing steadily. A good alternative for synthetic insecticides is natural compounds, including essential oils (EO). This work assessed toxicity of essential oils extracted from Artemisia annua, A. absi

6. Box–Behnken experimental design for extraction of artemisinin from Artemisia annua and validation of the assay method
ABSTRACT Obtaining artemisinin and its derivatives is very costly, which limits access to low-income people. Some hydroalcoholic extract of Artemisia annua L., Asteraceae, which has shown comparable antimalarial activity could be an alternative to the purified compound, especially if the cultivars have higher content of artemisinin. The objective of this stu

7. In vitro and in vivo antileishmanial activity of Artemisia annua L. leaf powder and its potential usefulness in the treatment of uncomplicated cutaneous leishmaniasis in humans
ABSTRACT INTRODUCTION: Cutaneous leishmaniasis (CL) is a tropical disease that affects millions of individuals worldwide. The current drugs for CL may be effective but have serious side effects; hence, alternatives are urgently needed. Although plant-derived materials are used for the treatment of various diseases in 80% of the global population, the valid

8. Artemisia annua increases resistance to heat and oxidative stresses, but has no effect on lifespan in Caenorhabditis elegans
Abstract It is suggested that oxidative stress induced by cellular reactive oxygen species is one of the major causal factors of aging. The effect of dietary supplementation of anti-oxidants on response to environmental stressors and lifespan has been studied in various model organisms. In the present study, we examine the effect of Artemisia annua extract o

10. Atividade ovicida e larvicida do extrato hidroalcoólico de Artemisia annua sobre parasitas gastrintestinais de bovinos
Os parasitas gastrintestinais causam enorme prejuízo econômico na bovinocultura, tanto nacional como mundial, ocasionado principalmente por Bunostumomsp., Cooperiasp. e Trichostrongylussp. O objetivo deste trabalho foi determinar a eficácia in vitro do extrato hidroalcoólico de Artemisia annua(H.7) frente a esses endoparasitas. O H.7 foi produzido com se
