Evaluation of chemical composition, some elements and antioxidants to various solvent extracts from Ruta chalepensis L. plant growing in al-jabal al- khadar region, Libya
Keywords:
Ruta chalepensis L, Medicinal plants, Polar solvents, Flavonoids, Mineral elements.Abstract
This study was conducted to evaluate the active substances and antioxidants of Ruta chalepensis L. in two types of different polar solvents (ethanol - hexane). It is one of the medicinal plants of commercial importance. It was collected in May 2023 in the city of Al-Qubba, located in northeastern Libya in the al-jabal al-khadar region, drying it and preparing extracts (flowering tops/seeds, leaves, stems). The results of detecting the active ingredients showed the superiority of the solvent hexane over ethanol, especially in leaves, while the highest values of mineral elements(sodium/potassium and copper) recorded for the leaves in the solvent ethanol, respectively (9.14 / 5.9 / 42), whilst the highest value for iron was recorded in the flower tips and seeds in hexane, about 2.2 ,This demonstrated the superiority of ethanol over hexane in extracting mineral elements and in addition to estimating the percentage of antioxidants for each studied parts, and they showed the highest value in the leaves and flowering tops 0.3µg/g, and the lowest value in the stems, 0.09µg/g. This supports that the higher the percentage of phenolic content of the plant, the greater its antioxidant activity, which gives it great potential for use as a natural antioxidant.
