A Study of antioxidant properties of some different species of the Malvaceae family using HPTLC and multivariate analysis technique. |

| چکیده انگلیسی مقاله |
The Malvaceae family contains at least 243 genera and 4225 species in the world and 11 genera and 70 species in Iran, which are seen as herbs, shrubs, and trees. This family has been not only economically but also medicinally considered in traditional medicine. This work was initiated with classification and determination of antioxidant properties of 9 species using high performance thin layer chromatography (HPTLC) and Principal Component Analysis (PCA) technique. Extraction was performed by soaking in ethanol solvent and placing it on a Stirrer magnetic. Then, different solvent systems were investigated. The hexane-ethyl acetate-acetic acid mobile phase (4: 5: 1) was selected. Free radical scavenging activity was evaluated by HPTLC with DPPH test and total phenolic content was evaluated by FeCl3 test and vitamin E content of the species. Data analyzed using MATLAB software and PCA technique For classification. The results of DPPH test showed that, Abutilon theophrasti, Malva sylvestris , Gossypium hirsutum and Alcea rosea (Purple petals) were in one batch and had high free radical scavenging activity. According to the FeCl3 test, samples of Abutilon theophrasti, Malva sylvestris and Alcea rosea )Purple petals ( were in the same category and had a high phenolic content. According to the vitamin E test, Abutilon theophrasti and Malva sylvestris placed in the same category and presented a high amount of vitamin E. Antioxidant activity of Abutilon theophrasti and Malva sylvestris was higher than other samples. Therefore, Abutilon theophrasti and Malva sylvestris can be assumed as a rich source of compounds with antioxidant properties in the food and drug industry to maintain benefited human health. Also in this report, the extract of common Alcea rosea L. plant (white petals) was analyzed by GC-MS to identify phenolic compounds. The results of GC-MS showed that among the identified compounds, 8 are phenolic compounds, of which 4-Mercaptophenol (9%) has the highest percentage among phenolic compounds. This compound with the chemical formula C6H6OS has antioxidant properties. |
