In vitro study on metabolite profiles of bioactive xanthones isolated from Halenia elliptica D. Don by high performance liquid chromatography coupled to ion trap time-of-flight mass spectrometry.
Beijing, China. In J Pharm Biomed Anal, Apr 2012
The metabolisms of five xanthones isolated from a Tibetan medicinal herb Halenia elliptica D. Don, including 1-hydroxy-2,3,5-trimethoxy-xanthone (HM-1), 1-hydroxy-2,3,4,7-tetramethoxy-xanthone (HM-2), 1-hydroxy-2,3,4,5-tetramethoxy-xanthone (HM-3), 1,7-dihydroxy-2,3,4,5-tetramethoxy-xanthone (HM-4) and 1,5-dihydroxy-2,3-dimethoxy-xanthone (HM-5), were studied in rat liver microsomes in vitro.

Holmium:yttrium-aluminium-garnet lithotripsy is more effective than pneumatic lithotripsy for ureteral calculi, but no more effective than shock-wave lithotripsy (Dornier HM-3) for distal ureteral calculi.
