Long Time

Artemisia annua L. (Asteraceae) still represents the only source of artemisinin, considered as one of the most important drugs for the treatment of malaria and which, more recently, has been shown to be effective against numerous types of tumors. The foliage and inflorescence of A. annua also yield an essential oil upon hydrodistillation. This oil has been evaluated at different development stages (pre-flowering and flowering) by GC/MS. The volatile oil from plants at full blooming showed numerous constituents, with germacrene D (21.2%), camphor (17.6%), β-farnesene (10.2%), β-caryophyllene (9%), and bicyclogermacrene (4.2%) among the main ones. Aromatic waters, after extraction with n-hexane, showed the presence, among others, of camphor (27.7%), 1,8-cineole (14%), artemisia ketone (10.1%), α-terpineol (6.1%), trans-pinocarveol (5.4%), and artemisia alcohol (2%). From plants at the pre-flowering stage, aromatic waters were obtained with camphor (30.7%), 1,8-cineole (12.8%), artemisia alcohol (11.4%), artemisia ketone (9.5%), alpha-terpineol (5.8%), and trans-pinocarveol (3.0%) as the main constituents. The qualitative and quantitative profiles of the two aromatic waters were similar. These results permitted the conclusion to be made that A. annua could be harvested a long time before the onset of flowering to obtain higher yields of artemisinin or could be allowed to attain maturity to obtain valuable yields of volatiles.

AbstractThe essential oil of Artemisia annua L., a weed collected from northern Iran, was studied for its toxicity and physiological aspects on 4th instar larva of the cotton bollworm Helicoverpa armigera Hübner in controlled conditions (26±1°C, 65±10% RH and 16 L : : 8 D h). The artificial diet was used as a medium for investigating the toxicity and the effect of LC10, LC30, LC50, and LC90on the feeding efficiency of 4th instar larva. The essential oil in doses of LC10, LC30, LC50, and LC90were estimated to be 2.01%, 3.86%, 6.07%, and 18.34%, respectively. The activity of α-amylase, protease, lipase, general esterases, and glutathione S-transferase and protein, triglyceride, glucose for treated larva were measured. The results showed that all of these parameters were decreased compared with the control. Hence, A. annua essential oil is suggested as a botanical for controlling this important pest of field crops.

Aim. The aim of the work was to assess the composition of biologically active compounds in plants of Artemisia annua L. Methods. The plants were grown on the experimental plot of the Central Botanical Garden of the National Academy of Sciences of Belarus. Essential oil from the above-ground mass was isolated by the method of water-steam distillation. To analyze the content of flavonoids and hydroxycinnamic acids, we used the method of quantitative extraction and spectrophotometric determination of the total content of hydroxycinnamic acids in the presence of flavonoids in plant extractive substances, and the method of Folin-Chocalteu was used to determine the content of phenolic compounds. Analysis of the essential oils was performed by GC and NMR. The analysis of the content of phenolic acids in extracts was performed by HPLC. Results. The genetic potential of A. annua was evaluated under conditions of the central agroclimatic zone of Belarus. The yield and composition of essential oils, the content of phenolic compounds and flavonoids, the composition of phenolic acids were studied. Conclusions. A. annua in the conditions of the central agroclimatic zone of Belarus contains essential oil, which is dominated by isoartemisia ketone, β-selinene, β-myrcene and camphor. In the above-ground mass phenolic acids including chlorogenic acid and isomers of caffeoylquinic acid were predominant in the composition of phenolic compounds. Keywords: annual wormwood, essential oil, phenolic compounds, phenolic acids.

Artemisinin Content

Artemisinin extracted from Artemisia annua has been used efficiently in malaria treatment since 2005. In this study, the variations in plant parameters (plant biomass, glandular trichome density, essential oil total chemical content, artemisinin production, and polyphenol oxidase (PPO) activity) were tested under different soil types (Luvisol, Gleysol, Anthrosol and sterile peat) and cultivation conditions (potted plants in semi-open field, and open field experiments) for plants inoculated with arbuscular mycorrhizal fungus (AMF) Rizophagus irregularis. Under semi-open field conditions, the AMF colonization of A. annua plant roots varied, and presented the highest percentage in Luvisol and sterile peat. The increase in the root colonization rate positively influenced some plant parameters (biomass, glandular trichome density, artemisinin concentration, essential oil quantity and composition), but no effects on PPO enzyme activity were detected. AMF fungus R. irregularis significantly increased the artemisinin content and essential oil yield of plants cultivated in Luvisol, Gleysol, Anthrosol and in peat. These soil types can offer appropriate conditions for A. annua cultivation and artemisinin production even on a smaller scale. Under open field conditions, low (about 5%) AMF colonization was observed. No differences in artemisin contents were detected, but essential oil yield significantly increased compared to control plants. AMF treatment increased beta-farnesene and germacrene D concentrations in Artemisia plants in the open field experiment.
