Abstract
The Hibiscus syriacus L. family Malvaceae is cultivated in Egypt and has been used in folk medicine to treat many health problems due to its antipyretic and anthelmintic nature. Hibiscus syriacus L. is a highly deciduous flowering shrub reaching 2–4 m. Genomic DNA was studied using RAPD-PCR and ISSR. The analysis of the amplified fragments generated by RAPD reactions revealed that the genetic profile of Hibiscus syriacus L. produces diverse molecular patterns. The primers OPA-20 and OPB-14 can be used for the identification of this species since they generate producible fragments. The ISSR analysis revealed 100% polymorphism when compared to a sample of Hibiscus sabdariffa L. and indicated variability in morphological characteristics and/or biological activity. The highest percentage of protein and amino acid contents were predominant in the leaves of Hibiscus syriacus L. followed by its flowers and stem respectively. Moreover, a proximate analysis of the flowers, leaves and stem was carried out; the highest percentage of moisture (10.13) and ash (17.40%) contents were in flowers, while the leaves and stem had less of these contents. Meanwhile, the stem showed the highest percentage of fiber content (36.98 %) followed by flowers and leaves.

Summary
Malvaceae belongs to the order of Malvales, which is a family of dicotyledonous flowering plants. It contains about 244 genera with around 4,225 known species (Christenhusz and Byng, 2016). Malvaceae plants are distributed worldwide and are characterized by stellate simple uni-cellular hairs. Either annual or perennial, and characterized by the presence of stellate and/or simple unicellular hairs. They are famous for their lobed, alternate petiolate leaves with an obtuse truncated base; their flowers are axillary and solitary (Welsh, 1980)
