The full length sequences of dxs, dxr, g10h, sls, tdc, str and dat which encoded key enzymes involved in terpenoid indole alkaloids (TIAs) biosynthesis pathway were obtained via two-step Gateway PCR method, with the tr.

Monoterpenoid indolopyridine alkaloids are a small group of alkaloids composed of trymptamine and substituted pyridine moieties, the latter being derived from a secologanin aglucone unit by insertion of nitrogen.

Six indole alkaloids were separated from the bark of Anthocephalus chinensis(Anthocephalus cadamba) and they were identifed as vallesiachotamine(Ⅰ),isovallesiachotamine(Ⅱ),strictosamide(Ⅲ), cadambine(Ⅳ),desoxycordifoline(Ⅴ) and 5α carboxystrictosidine(Ⅵ)on the basis of their spectral data and physicochemical properties.

Objective To study indole alkaloids of Ervatamia hainanensis.
