Artemisia annua as a Traditional Herbal Antimalarial
نویسندگان
چکیده
A. annua is so named because it is almost the only member of the genus with an annual cycle. It is a shrub, often growing over 2 m high (Ferreira et al., 1997; see Figure 3.1 and Figure 3.2). Its leaves and flowers contain artemisinin, first isolated in China in 1971; this is the constituent with the greatest antimalarial activity (see Table 3.3). Artemisinin has been found in only two other species, Artemisia apiacea and Artemisia lancea (Tan et al., 1998).

The antimalarial drug artemisinin is a natural product produced by the plant Artemisia annua. Extracts of A. annua have been used in Chinese herbal medicine for over two millennia. Following the re-discovery of A. annua extract as an effective antimalarial, and the isolation and structural elucidation of artemisinin as the active agent, it was recommended as the first-line treatment for uncompl...
متن کاملExtraction of the Antimalarial Artemisinin from Artemisia Annua L. Leaves with Supercritical Co2
The antimalarial artemisinin, the active principle of the plant Artemisia annua L., was extracted by Supercritical Fluid Extraction (SFE). Soxhlet extraction was studied as comparison processes. The extracts were analyzed by the indirect method GC-FID. The maximal extraction yield (1.82%DW) was obtained by SFE at T=40°C, P=200bar, CO2flow=4.5g/min, and 20% ethanol as modifier. The artemisinin e...
متن کاملThe potential of Artemisia annua L. as a locally produced remedy for malaria in the tropics: agricultural, chemical and clinical aspects.
The plant Artemisia annua L. (Asteraceae) is listed in the Chinese pharmacopoeia as a remedy for various fevers including malaria, and contains the well-established antimalarial compound artemisinin. In this study, a hybrid form of A. annua was successfully cultivated in Central Africa. The aerial parts of the plant contained 0.63-0.70% artemisinin per dry weight, and approximately 40% of this ...
متن کاملScreening of Natural/Synthetic Compounds for Antimalarial Activity
Plants have been used as a traditional medicine for the treatment of malaria. Plants may provide drugs directly such as quinine from cinchona bark or they may provide template molecules on which to base further new structures by organic synthesis—artemisinin from Artemisia annua. At the NIMR, efforts are being made to do primary screening of crude extracts of plant products to screen different ...
