عنوان مقاله [English]
To evaluate the quality and quantity of primary and secondary metabolites at different phenological stages of Brazmbl medicinal plants, plant organs at both vegetative and flowering stages of Vamanan region in Āzādshahr were collected and dried. Whole plant extracts from Proveskia abrotanoides were used in this study at both vegetative and flowering stages to identify and evaluate the quality of tannins, saponins, anthocyanins and terpenoids compounds, flavones, and flavonoids. Also some primary metabolites such as soluble and insoluble carbohydrates, proline and total phenol in roots, stems, leaves, and flowers of plant were evaluated quantitatively. Qualitative analysis showed that saponins, anthocyanin, and tannin compounds were present at both vegetative and flowering stages of Proveskia abrotanoides. Also, quantitative analysis showed the maximum amount of starch in the root and the highest concentration of soluble carbohydrates, proline, and phenolic compounds in the leaves at vegetative stage. Overall, the results showed that at the vegetative stage regardless of starch, leaves had the highest soluble carbohydrates, proline, and phenolic compounds while at the reproductive stage root contained the highest level of these compounds.
