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 sp...

Herbs have long been used in the treatment of various disorders in traditional medicine since ancient age. Artemisia absinthium, one of these herbs, has traditionally been used in different societies for antibiotic, antiparasitic, antifungal and antipyretic purposes.

The first study of the aphid fauna from Chukotka Autonomous Okrug has been made; 18 species are reported from this territory, the most north-eastern of Russia and of the Palaeartic Region. Five new species are described: Aphis aquilonalis sp. nov. on Rumex arcticus Trautv.; Aphis beringiensis sp. nov. were collected by yellow trap; Macrosiphoniella (Asterobium) jaroslavi sp. nov. on Artemisia a...

This study aimed to determine phenolic compounds of Artemisia spicigera (family Asteraceae) growing in East-Azarbaijan province of Iran. 20%, 40 % and 60% SPE fractions of methanolic extract of A. spicigera, were subjected to reversed phase preparative HPLC, with the mobile phase consisted of methanol and water. Structural identification of phytochemicals by spectroscopic methods including UV a...

The clinical assays of Jerome Munyangi in RDC [1,2] following those of Patrick Ogwang in Uganda [3] have clearly shown that Artemisia annua has prophylactic properties against malaria, but it is not known how and why. Artemisia plants are rich in polyunsaturated fatty acids (PUFA) which generate prostaglandins and stimulate monocytes. PUFAs possess well documented antimalarial and prophylactic ...
