Abstract: Abstract Yunnan Province is very rich in Lichen plant resources, of which many kinds can be provided for the exploitation and utilization in food, vege- table, perfume, medicine, and dyestuff, etc. In their studies on the exploitation and utilization of Lichen plants, the authors examined the constituents of seven species of Lichen plants. The names of these plants and the isolated chemical constituents are as follows: 1. Alectoria asiatica DR. ...Usnic acid (1 ). 2. Alectoria sulcata Nyl. ...Virensic acid (2 ), Ethyl haematommate(3 ), Rhizonic acid (4 ) and Haematommic acid (5 ).
