A study of Minerals Content and Chemical Composition of Shih (Artemisia herba alba).

Abstract

The aim of this study was to investigate the chemical compositions of the aerial part of Shih (Artemisia herba alba) and it’s essential oil. Areial part of Shih sample was purchased from Omdurman Market(Sudan). The minerals content of the aerial part of Shih was measured by the Inductively coupled plasma (ICP) instrument. The (ICP) analysis showed a presence of Fe (25 mg/l), S (21 mg\l), P (11mg/l), Al (6.1 mg/l), Mg (0.58mg/l), Ca (0.43mg/l), Mn (0.62mg/l), Na (0.32mg/l), Er (0.55mg/l), Ti (0.25mg/l), Cs (0.56mg/l), as most available minerals in Shih(Artemisia herba alba). Aqueous extract of Shih sample was obtained using soxhlet system. Steam distillation was used to extract the essential oil from Shih sample. The Oil yield percentage was determined (0.68% ml/100g). The aerial part aqueous extract and essential oil of Shih sample was analyzed by GC-MS instrument.. GC-MS analysis of the aqueous extract showed a presence of fifteen constituents, dominated by bicycle{10.4.0}hexadecane,14,15diethyl(39.5%), alpha-d-manofuranoside, methyl (20.08%), Ledol (13. 41%),and lilac aldehyde C (5.58%) as the most major constituents. The GC-MS analysis of Shih essential oil showed a presence of seventy-one constituents, dominated by Camphor (14.37%), Isophorone (13.39%), Cinnamic acid, ethyl ester (10.51%), cinnamaldehyde-(E) (6.11%), 1,3-cyclopentadiene,5,5-dimethyl,1,1 diethyl (5.47%) and Methylene (3.70%), as the most major constituents.
