Phenylpropanoids have been known for numerous biological activities such as alleviation of fever, relief, antioxidative activity, growth inhibitory activity for spore of plant, or higher plant, insect attraction activity, and so on. 

Higher plants produce diverse chemicals such as alkaloids, terpenoids, and phenolic compounds (phenylpropanoids and flavonoids) in secondary metabolism. Among these chemicals, benzylisoquinoline alkaloids (BIAs) are very important in medicine due to their high biological activities. However, extraction yields from plants are low because most of these metabolites accumulate at low levels in plant cells. There has been increasing interest in the microbial... 

The downstream synthesis of two coumarins, ayapin (6,7-methylenedioxy-coumarin) and sco-poletin (6-methoxy-7-hydroxy-coumarin), is of biological interest due to their apparent roles as phytoalexins. Their accumulation has been correlated with resistance to pathogens in Helianthus (Tal and Robeson, 1986a, 1986b) and as feeding deterrents (Olson and Roseland, 1991). Both compounds are found in Jerusalem artichoke tubers (Cabello-Hurtado et al., 1998), and their synthesis via the phenylpropanoid pathway involves the first three steps leading to the activation of 4-coumaroyl CoA (Werck-Reichhart, 1995). Several routes have been postulated ayapin does not appear to be derived from scopoletin (Cabello-Hurtado et al., 1998).
