Ipomoea asarifolia

Pale, E. et al., Acylated anthocyanins from the flowers of Ipomoea asarifolia, Phytochemistry, 48, 1433, 1998. 

During the period of this review. Pale et al. have isolated a triacylated-tetraglucosylated cyanidin derivative (243) from flowers of Ipomoea asarifolia, which contained E-3,5-dihydroxycinnamic acid linked to the 6-position of one of the glucosyl moieties. This acyl...

(2008) Biosynthesis and accumulation of ergoline alkaloids in a mutualistic association between Ipomoea asarifolia (Gonvolvulaceae) and a Clavicip-italean fungus. Plant Physiol, 147,296-305. 

Ergobalansine (9 Table I) was first identified in Cyperus species that had symbiotic Balansia species, which also produce this alkaloid in culture (13). Later, ergobalansine was also identified in the plant, Ipomoea asarifolia (family Convolvulaceae) (49). Based on recent studies in whieh EA were eliminated from I. asarifolia by fungicide treatment (50), it seems reasonable to expect that 9 is produced by a fungal symbiont of this plant.

Cuscutin, a metabolite of the holoparasitic Cuscuta lehmanniana Bge. growing on elms (Ulmus L., Ulmaceae), turned out be an ester with an unusual substitution pattern in its acyl residue, namely hexadecyl 3,5-dihydroxycinnamate (Fig. 6.3). This metabolite could not be detected in the host (Kamilov and Nikonov 1977). Snch a rare 3,5-dihydroxycinnamoyl moiety is also present in an anthocyanin of Ipomoea asarifolia (Table 6.1).
