Study of the phenolic compounds of some species of malvaceae

Author(s): Ahmed Ali Hussein, Ahmed Abbas Motar


This study was conducted to investigate the chemical and molecular relationships and compare them to the leaves of eight species, varieties and species belonging to the Malvaceae family in Iraq for the period from 10/8/2022 to 1/2/2023, as the following species were studied: Abelmoschus esculentus var. BATHRAH, Abelmoschus esculentus var.LAHLOUBA, Abelmoschus esculentus var.HUSSAINAWI, Hibisscus sabdariffa var.RED, Hibisscus sabdariffa var.STRIPED, Malva parviflora, Althaea officinalis var.RED, Althaea officinalis var.WHITE Obtained from field trips and tours. The results of the chemical study determined the concentrations of six secondary (phenolic) compounds using High Performance Liquid Chromatography (HPLC) technology belonging to Abelmoschus esculentus L. They are (protocatechuic acid, catechin, Quercetin-3-o-gentobioside, Rutin, Isoquercetrin, Quercetin). The highest concentration of the compound Quercetin-3-o-gentobioside, which reached (1.2 mg / g), and the lowest concentration of the compound Rutin, which reached ((0.35 mg / g). Also, five secondary (phenolic) compounds belonging to the type L Malva parvflora were identified (P-coumaric acid, Apigenin (Naringenin, Luteolin, Cinnamic acid), as the highest concentration of the compound Naringenin reached ((1.4 mg / g in When the lowest concentration of the Luteolin compound was ((0.19 mg / g) and nine secondary (phenolic) compounds belonging to the species L Althaea officinalis were identified, which are (Gallic acid, Hydroxy benzoic acid, ferulic acid, Caffeic acid, Chrysin, P-coumarins, Vanillic acid, Ellagic acid, Syringic acid), where the highest concentration of the compound P-coumarins was (2.1) mg / g, and the compound with the lowest concentration was the compound Vanillic acid, which reached ((0.15 mg / g). Ten secondary (phenolic) compounds belonging to the Hibiscus sabdariffa species were identified. L are (Gossypetrin, Sabdaretin, Gossyptin, Chlorogenic acid, (Hibiscetin, Rutin, protocatechuic acid, Eugenol, Quercetin, Kaempferol), as the highest concentration of the Quercetin compound reached ((1.4 mg / g) and the lowest concentration of the Eugenol compound reached (0.45) mg / On the basis of these compounds, it became clear that all varieties differed by the concentration of the separated compounds, and the chemical study proved its usefulness in distinguishing, separating, and finding evolutionary links between the studied varieties.
