Botanical Name - Artemisia annua Category - Medicinal Form - Dry Part Used - Leaves General Information - Artemisia annua belongs to the plant family of Asteraceae and is an annual short-day plant. Its stem is erect brownish or violet brown. The plant itself is hairless and naturally grows from 30 to 100 cm tall, although in cultivation it is possible for plants to reach a height of 200 cm. The leaves of A. annua have a length of 3 - 5 cm and are divided by deep cuts into two or three small leaflets. The intensive aromatic scent of the leaves is characteristic.[8] The artemisinin content in dried leaves is in between 0% and 1.5%.[9] New hybrids of Artemisia annua developed in Switzerland can reach a leaf artemisinin content of up to 2%.[10] The small flowers have a diameter of 2-2.5 mm and are arranged in loose panicles. Their color is green-yellowish. The seeds are brown achenes with a diameter of only 0.6-0.8 mm. Phytochemicals- "The major active constituent of Artemisia annua, Artemisia apiacea, and Artemisia lancea is artemisinin. Derivatives of this compound include arteether, artemether, artemotil, artenimol, artesunate, and dihydroartemisinin, which, along with artemisin, are currently being used to treat drug-resistant and non-drug resistant malaria. The aerial parts of Artemisia annua contain 0.01-0.8 % of artemisinin per dry weight. Other constituents of Artemisia annua include deoxyartemisinin, artemisinic acid, arteannuin-B, stigmasterol, friedelin, friedelan-3 beta-ol, artemetin, and quercetagetin 3',4'-tetramethyl ether. The essential oil of Artemisia annua aerial parts contains 44% camphor, 16% germacrene D, 11% trans-pinocarveol, 9% beta-selinene, 9% beta-caryophyllene, and 3% artemisia ketone."

SUMMARY Bilirubin: This test is based on the coupling of bilirubin with a diazotized dichloroaniline in a strongly acid medium. The colors range from light tan to reddish-brown. Ketone: This test is based on the reaction of acetoacetic acid with sodium nitroprusside in a strongly basic medium. The colors range from beige or buff-pink color for a Negative reading to pink and pink-purple for a Positive reading. Specific Gravity: This test is based on the apparent pKa change of certain pretreated polyelectrolytes in relation to the ionic concentration. In the presence of an indicator, the colors range from dark blue or blue-green in urine of low ionic concentration to green and yellow-green in urine of higher ionic concentration. Blood: This test is based on the pseudoperoxidase action of hemoglobin and erythrocytes which catalyzes the reaction of 3,3, 5, 5-tetramethyl-benzidine and buffered organic peroxide. The resulting colors range from orange to yellow-green and dark green. Very high blood concentration may cause the color development to continue to dark blue. pH: This test is based on the well known double pH indicator method, where bromothymol blue and methyl red give distinguishable colors over the pH range of 5-9. The colors range from red-orange to yellow and yellow-green to blue-green. Protein: This test is based on the protein error-of-indicator principle. At a constant pH, the development of any green color is due to the presence of protein. Colors range from yellow for a �??Negative�?? reaction to yellow-green and green to blue-green for a �??Positive�?? reaction. Urobilinogen: This test is based on a modified Ehrlich reaction in which p-diethylaminobenzaldehyde reacts with urobilinogen in a strongly acid medium. Colors range from light pink to bright magenta. Nitrite: This test depends on the conversion of nitrate to nitrite by the action of Gram-negative bacteria in the urine. The nitrite reacts with p-arsanilic acid to from a diazonium compound in an acid medium. The diazonium compound in turn couples with 1,2,3,4-tetrahydrobenzo(h) quinolin to produce a pink color. Leukocytes: This test is based on the action of esterase present in leukocytes, which catalyzes the hydrolysis of an indoxyl ester derivative. The indoxyl ester liberated reacts with a diazonium salt to produce a beige-pink to purple color. Ascorbic Acid: The composition comprises of a complex chelating agent with a polyvalent metal ion in its higher state and an indicator dye that can reacts with the metal ion in its lower state to produce a color change from blue-green to yellow.
