Plant pigments (antioxidants) of medicinal plants Malva silvestris L. and Malva moschata L. (Malvaceae).Bosn J Basic Med Sci. 2005 May; 5(2):53-8.BJ
Qualitative-quantitative structure of plant pigments in wild plants Malva silvestrs L. and Malva moschata L. (Malvaceae), which were collected in 20 locations in Sarajevo area and surroundings, was tested during spring and summer in 2003. Acetone extracts of both categories were made and rising paper-chromatography done for the purpose of qualitative analysis. Quantitative analysis was done by spectrophotometry. Chlorophyll a, chlorophyll b and xanthophylls presence was confirmed by separation of pigments from acetone extract of these plant species. Spectrophotometric analysis of acetone extracts showed these results (given in mg/L): chlorophyll a 2,386, chlorophyll b 0,332 and carrotenoides 1,037. Data given in mg/g dry substance are: chlorophyll a 1,193x10(-2), chlorophyll b 1,66x10(-3), and carrotenoides 5,185x10(-3). Pigments structure (in mg/L) in species Malva moschata is 1,6 for chlorophyll; 1,419 for chlorophyll b; and 0,364 for carrotenoides. Data given in mg/g are: chlorophyll a 8x10(-3), chlorophyll b 7,09x10(-3), and carrotenoides 1,82x10(-3). Considering that species Malva moschata L. grows on ecologically clear soils as opposed to well-known medicinal species Malva sylvestris L., and considering the production of phytomass, phytochemical structure and pharmacological influence it can be considered very medical and be given advantage over this wider spread category.
