文摘
- •
N-Benzoyltyramine (1) was identified as a UV-inducible compound from rice leaves.
- •
Two new casbene diterpenes (2 and 3) were isolated from UV-irradiated rice leaves.
- •
Compounds 2 and 3 may be biosynthetic intermediates of a casbene-type phytoalexin.
- •
Two known amides were recognized as phytoalexins in the rice–M. oryzae system.
