SAJEEVAN.P,NOTED ENVIRONMENTALIST IN KAMBALLUR HAS INFORMED US THAT ORILATHAMARA( A RARE MEDICINAL PLANT ) HAS BEEN IDENTIFIED TO GROW IN AKKOKAVU,KAMBALLUR.
WE HAVE DECIDED TO MAKE A PRIMARY STUDY OF THE BIODIVERSITY THERE FROM TOMORROW ONWARDS.
Nervilia aragoana Gaud., the plant well known in malayalam as Orilathamara is a medicinally important small tuberous terrestrial orchid with wide therapeutic potentials. The plant belongs to Orchidaceae family. It is reported to be near threatened in Karnataka, endangered in Thamilnadu and vulnerable in Kerala and is included in the negative list of exports notified by Govt. of India. It is found in India especially in the higher altitudes of Western Ghats. Nervilia has got many uses in traditional and folk medicine. Its leaf paste is used against head ache, leaf decoction as women tonic and tubers for postnatal care and also to induce lactation. Leaves and tubers are the major medicinal parts. Biochemical investigations revealed that the plant mainly contains flavanoids, sterols, glycosides and tannins. The flourescent studies of the aqueous extract revealed a milkish green flourescence under UV 365 nm and a good yellowish green flourescence under UV-254nm confirming the presence of some chromophores. The TLC finger prints developed gave 6 specific flourescent bands. The salient findings observed in this preliminary study are documented as means of authentication. The specific TLC fingerprint developed in the study will be help in the correct identification of the genuine samples of this endangered plant, preparation of monograph as well as to help distinguishing the plant from its adulterants.
