Abstract: Parmotrema tinctorum is an edible lichen used as a spice for flavouring food. In Kerala, southern part of India, its occurrence is reported in the evergreen/sub-tropical forests at an altitude of 750-2300m especially in Wayanad and Idukki districts. Despite large collection from the forests of Kerala for use as spice, the reports on its nutritional composition is meager. In the present study, the phytochemical screening and evaluation of proximate composition of edible lichen viz. Parmotrema tinctorum (Nyl.) Hale (Parmeliaceae) was carried out. Phytochemical screening of P.tinctorum extracts showed presence of carbohydrates, phenols, flavanoids, tannins, terpenoids, coumarins and saponins. The powdered lichen was subjected for proximate analysis to estimate moisture, ash, total fat, total carbohydrate, crude protein and crude fibre. P. tinctorum exhibited high content of ash, crude fibre and crude protein indicating the nutritional benefits of this lichen.
