Plant parasites are known to obtain primary and secondary compounds from their hosts. Mistletoes or parasitic plants are growing on various trees and belong to the Loranthaceae family. Numerous mistletoes don’t synthesize or modify the secondary compounds taken up from their hosts’.The hosts significantly influenced the phytoconstituents of hemi parasites. In traditional systems as well as in the modern system of medicine the plant Azadirachta indicais used as a medicine for various ailments and so the parasite Loranthus longiflorus grown on neem tree was chosen for the study. The present study is carried out to detect the phytochemical constituents of Host-Azadirachta indica and parasite Loranthus longiflorus from the Hyderabad region. Phytochemical analysis of methanolic leaf extracts revealed the presence of tannins, phenols, and Anthraquinones in both the host and parasite. GCMS analysis revealed the presence of five bioactive compounds in the host and parasite with varied compositions. The phytochemical and GCMS analysis indicated similarity in presence of phytoconstituents in both the host and parasite.
