RESUMEN

Phytochemical investigation of the plant Clerodendrum phlomidis Linn. F. (Lamiaceae) has now led to the isolation of two new flavonoid glycosides (1, 2) together with six known compounds identified as pectolinaringenin (3), pectolinaringenin-7-O-ß-D-glucopyranoside (4), 24ß-ethylcholesta-5,22E,25-triene-3ß-ol (5), 24ß-ethylcholesta-5,22E,25-triene-3ß-O-ß-D-glucopyranoside (6), (2S,3S,4R,10E)-2-[(2'R)-2'-hydroxytetracosanoylamino]-10-octadecene-1,3,4-triol (7) and andrographolide (8) mainly by spectroscopic analysis. Compounds 4 and 6-8 are reported for the first time from C. phlomidis.
