PHYTOCHEMICAL AND BIOLOGICAL STUDY ON CERTAIN PLANTS BELONGING TO FAMILY ROSACEAE

Abstract

Family Rosaceae is one of the largest plant families, it is comprised of 90 genera and 1500 species distributed all over the world except for the Antarctica. The family is famous for many edible fruits like apple, apricot, prunes, plums and berries in addition to the ornamental members represented mainly in genus Rosa. Genus Rosa represents the third famous genus belonging to the Rosaceae and is mainly characterized by ornamental flowers that are the backbone for many gardens all over the world. Although many phytochemical and biological studies were exploited on many species from genus Rosa but little was traced concerning the banksiae and polyantha species and from which the three varieties; Rosa banksiae var. banksiae Ait. (RBW), Rosa polyantha Thunb. ‘orange fairy’ (RPO) and Rosa polyantha Thunb. ‘white fairy’ (RPW) were chosen for in-depth phytochemical and biological studies.

This study was divided into three main parts:

Part I: Cultivation and genetic characteristics of selected Rosa species family Rosaceae Chapter 1: Cultivation of selected Rosa species family Rosaceae The three Rosa varieties in this study were successfully cultivated during Spring 2016 for the first time at the Medicinal Plants Research Station, Faculty of Pharmacy, Ain Shams University (PS) with the aim of providing a renewable source of them and also to compare their relative chemical profiles to their collected (CS) counterparties at the start of the study. During Spring 2021 the chemical profiles of both the collected (CS) and cultivated roses (PS) were compared using GC/MS and LC/MS analyses (as discussed in part II, chapter 3 and 4).
