title: Phytochemical Study of Isoplexis chalcantha.
abstract: Three cardioactive glycosides were isolated from ISOPLEXIS CHALCANTHA. Two were identified as uzarigenin-canarobioside and uzarigenin-digilanidobioside, previously found in other Isoplexis. The third glycoside must be uzarigenin-digitoxoside from the same source. The flavones apigenin, luteolin and their 7- Obeta- D-glycosides were also obtained, together with the salidroside [2-(4-hydroxyphenyl)-ethyl-1-beta- D-glucopyranoside].
