Abstract

Aster himalaicus a perennial plant grows only in the Himalayas at high altitudes 3600–4800 m such as in Nepal Sikkim Bhutan Burma Tibet and Yunnan Province of China The aerial parts of this plant have been extensively used as folk medicine in Tibet for treatment of coughs bronchitis hepatitis snakebite and so on 1 Several flavonoids isotated from Aster himalaicus were reported recently 2 For the purpose of searching for antibacterial sesquiterpenoids we investigated the chemical constituents of this plant collected in the marginal areas of QinghaiTibet Plateau in China Recently we reported a new and several known eudesmane sesquiterpenoid 3 To the best of our knowledge there have been only one eudesmane sesquiterpene 6amethoxy415eudesmen1βol obtained from Aster species before our research 4 Subsequent investigation of this plant resulted in the isolation of four eudesmane sesquiterpenoids of which compounds 2–4previously yielded their ester
