From the bark of Taxus yunnanensis , 15 non-taxane compounds were isolated. Through spectroscopic methods such as 1D and 2D NMR and MS experiments, one of them was determined as a new abietane-type diterpenoid named taxayunnin ( 1 ). The other 14 known compounds were identified as taxamairin C ( 2 ), taxamairin A ( 3 ), 3 β-hydroxy-sandaracopimaric acid ( 4 ), (+)-3-hydroxy-isodrimenin ( 5 ), rubrosterone ( 6 ), ponasterone A ( 7 ), ecdysterone ( 8 ), 20-hydroxy-echysone-20,22-monoacetonide ( 9 ), 7-oxositosterol ( 10 ), stigmast-4-en-6 β-ol-3-one ( 11 ), 5 α,6 β-dihydroxy-daucosterol ( 12 ), β-sitosterol ( 13 ), daucosterol ( 14 ), 1- O - β- d -glucopyranosyl-(2 S , 3 R , 4 E , 8 Z )-2- N -(2'-hydroxypalmitoyl)-octadeca-sphinga-4,8-dienine ( 15 ), respectively. Compounds 4 - 6 , 9 - 12 and 15 were isolated from Taxus plants for the first time. |
