title: A new phenanthrene with a spirolactone from Dendrobium chrysanthum and its anti-inflammatory activities.
abstract: Investigation of phenolic patterns from the stems of Dendrobium chrysanthum by HPLC-PDA-MS has led to the isolation of a new phenanthrene derivative with a spirolactone ring, dendrochrysanene (1), that proved to suppress the mRNA level of TNF-alpha, IL8, IL10, and iNOS in murine peritoneal macrophages. The structure of 1 was characterized on the basis of various NMR (1H, 13C, 1H-1H COSY, HMQC, and HMBC), mass spectrometry, and X-ray crystal diffraction data.
