Abstract

In this research work some bioactive molecules of Hypericum triqutrifolium Turra., were evaluated at vegetative (V), flowering (Fl) and fruiting (Fr)} developing stages during the growing seasons as natural products. HPLC was used for qualitative and quantitative of bioactive compounds, which compared with expected compounds such as: Sirginic, Querctrin, Apeginin, Karmeferol, Hypericin and Hyperforin. Different diversity and phytochemical composition among (V), (Fl), and (Fr) were observed. The highest concentration of quercitrin was obtained when plants fruited, whereas apigenin, kameferol and sriginic acid showed highest levels during flower development, while hyperforin in fruiting stage accumulated the highest concentration compared to vegetative and flowering. On the other hand, vegetative stage accumulated larger amounts of hypericin. Regarding to the bioactive accumulation in the individual plant parts, fresh fruit accumulate the highest level of hyperforin at fruiting stage, while it was not detected in stem during flowering and fruiting, whereas leaves produce more hypericin at flowering time
