The chromatographic separation of organic solvent extracts of liverwort led to the isolation of six compounds. 2-Chromenone (1), 3, 4-dihydroxy-cinnamic acid (2), 3, 3', 4', 5, 7-pentahydroxy-2-phenylchromen-4-one (3), kaemperol-3-O-${\beta}$-D-glucopyranoside (4), 3-[[3-(3,4-Dihydroxyphenyl)-1-oxo-2-propenyl]oxy]-1, 4, 5-trihydroxycyclohexane carboxylic acid (5) and quercetin-3-O-rutinoside (6) were isolated from the methanolic extracts of the all part of Climacium dendroides. Their structure were established by chemical and spectroscopic methods. All compounds were isolated for the first time from this plant Climacium dendroides.

All plants in natural ecosystems are living in symbiosis with endophytes. Recently, there has been an increasing interest in endophytes since these organisms can interact with the hosts and produce various structurally or biologically interesting molecules. This study aimed to identify these molecules from endophytes. Chemical investigation of Climacium dendroides-derived fungus Talaromyces sp. resulted in the isolation of two diphenyl ether derivatives, purpactin A (1) and penicillide (2), and two steroids, dankasterone A (3) and calvasterol B (4). The structures of the compounds were identified via extensive spectroscopic and spectrometric methods. Four compounds did not show any antioxidative activities in the on-line antioxidant activity screening system.
