Phytochemical investigations of the orchid family were performed for alkaloid constituents, identification and inheritance of flower pigments in the species of ornamental value. Apart from the presence of chlorophyll in green flowered forms and carotenoids in some yellow flowers, anthocyanidins are predominated. The cyaniding, pelargonidin and petunidin, and complex mixture of their glycosides and acylated derivatives are often present in a single flower. In the present investigation of the preliminary phytochemical study of leaf flavanoids contents of Orchidiaceae family members in the Tirunelveli hills of South India were analyzed and surveyed.
