Abstract
Chromatography techniques facilitate separation, purification, and identification of secondary compounds (natural products) in lichens and their mycobiont cultures. In particular, high-performance liquid chromatography (HPLC) plays a vital role in the identification of lichen substances because of its high sensitivity, speed, and reliability with the minimal sample. Therefore, we describe the extraction and HPLC protocol for the investigation of secondary compounds with a special focus on lichen mycobiont cultures.

Abstract
Chemical investigation of the lichen Parmotrema indicum Hale led to the isolation of one new diphenyl ether, parmetherine D (1), along with eight known compounds (2-9). The structures were determined by analysis of MS and NMR data and by comparison with the literature. Compounds 1, 2, and 7 were evaluated for α-glucosidase inhibition. Only compound 1 exhibited significant inhibition.
