xiphidium caeruleum/7 glucoside

Phytochemical analysis of Xiphidium caeruleum, a neotropical member of the family Haemodoraceae, resulted in the isolation and identification of a variety of phenylphenalenone-related compounds. The structures of four new phenylbenzoisochromenones (3, 6, 7, 10), a new phenylbenzoisoquinolinone (4),

We investigated the organ-specific phytochemistry of the inflorescences, leaves at different stages of senescence, and roots of Xiphidium caeruleum (Haemodoraceae) and elucidated the structure of six undescribed compounds. Among these, a phenylcarbamoylnaphthoquinone (PCNQ), representing the first

Phenylbenzoisochromenone glucosides (oxa-phenylphenalenone glucosides) occurring in some phenylphenalenone-producing plants of the Haemodoraceae undergo conversion to phenylbenzoisoquinolindiones (aza-phenylphenalenones) in extracts of Xiphidium caeruleum. Precursor-directed biosynthetic experiments

Phytochemical investigation of root cultures of Xiphidium caeruleum (Haemodoraceae) resulted in the structure elucidation of five previously undescribed phenylphenalenone-type compounds, structure revision of a phenylphenalenone glucoside, and identification of nine additional constituents
