Abstract


The aerial part of Pineapple weed (Matricaria matricarioides), an adulterant of Chamomile, was investigated for its chemical constituents. Nine compounds were isolated and identified as two spiroethers [cis - en - yn - dicycloether 1 and trans - en - yn - dicycloether 2], three coumarins [7 - methoxycoumarin (Herniarin) 3, umbelliferone 4 and 7 - methoxy - 3, 4 -dihydrocoumarin 5], phytol 6, luteolin - 7 - glucoside 7, (Z) - 2 - β - D - Glucopyranosyloxyl - 4 - methoxycinnamic acid 8, and (E) - 2 - β -D-Glucopyranosyloxyl - 4 -methoxycinnamic acid 9. By GC-MS analysis, the major components of the steam distilled volatile oil were identified as trans-en-yn-dicycloether and cis-en- yn-dicycloether, with the trans-form being more abundant than the cis-form. The results indicated some similarities between the constituents of Pineapple weed and those of German Chamomile. All these nine compounds are reported for the first time from Pineapple weed growing in Newfoundland. Compound 5 is reported from this plant genus for the first time.
