چکیده

Two polyacetylene glycosides, gymnasterkoreasides A and B, were isolated from the roots of Gymnaster koraiensis. Their structures were elucidated to be (3R)-8-decene-4,6-diyne-1,3-diol 1-O-beta-D-glucopyraside and (3R)-8-decene-4,6-diyne-1,3-diol 1-O-beta-D-apiofuranosyl-(1-->6)-beta-D-glucopyraside on the basis of spectroscopic analysis including COSY, HMQC, and HMBC experiments, as well as chemical methods, which confirmed the determination of a chiral center by the modified Mosher's method.

Gymnaster koraiensis and its major components, 3,5-di-O-caffeoylquinic acid and gymnasterkoreayne B, reduce oxidative damage induced by tert-butyl hydroperoxide or acetaminophen in HepG2 cells

We investigated the protective effects of Gymnaster koraiensis against oxidative stress-induced hepatic cell damage. We used two different cytotoxicity models, i.e., the administration of tert-butyl hydroperoxide (t-BHP) and acetaminophen, in HepG2 cells to evaluate the protective effects of G. koraiensis. The ethyl acetate (EA) fraction of G. koraiensis and its major compound, 3,5-di-O-caffeoy...

Inhibition of Osteoclast Formation and Bone Resorption by Gymnasterkoreayne F from Gymnaster koraiensis

INTRODUCTION Osteoclasts are multinucleated cells that are derived from the hematopoietic myeloid/monocyte lineage via the action of M-CSF and receptor activator of NF-κB ligand (RANKL) (1). Binding of RANKL to RANK activates and/or induces expression of the transcription factors NF-κB, AP-1, and NFAT2, which are important for osteoclast differentiation (1, 2). Fusion-induced osteoclast formati...

Molecular Characterization and Morphology of Two Endophytic Peyronellaea Species from Pinus koraiensis in Korea

Species of Phoma and its allies were isolated during a survey on the diversity of endophytic fungi associated with pine trees in Korea. Based on the phylogenetic analyses of internal transcribed spacer and β-tubulin gene sequences, two Phoma-like species from the needles of Pinus koraiensis were identified as Peyronellaea calorpreferens and P. glomerata. They were also morphologically identifie...

Molecular Identification of Endophytic Fungi Isolated from Needle Leaves of Conifers in Bohyeon Mountain, Korea

Fungal endophytes are microfungi that live in plants without causing apparent symptoms of infection. This study was conducted to identify endophytic fungi isolated from leaves of coniferous trees in Bohyeon Mountain of Korea. We collected leaves of two species of coniferous trees, Pinus densiflora and Pinus koraiensis, from 11 sites in the study area. A total 58 isolates were obtained and ident...
