摘要: Abstract Five new alkaloids together with 20 known ones were isolated from Alstonia rostrata, and identified on the base of NMR, MS, UV IR spectroscopic data. Additionally, alstrostine G (1) possessed an unprecedented 6/5/6/6/5/6-ring system. The analysis those alkaloids’ biosynthetic pathway partly indicated their reticulate metabolic relationship. research result disclosed diverse biogenesis monoterpenoid indole rostrata speciesin combination previous reported A.
