Received 23 December 1997; accepted 19 January 1998

Keywords:¹agetes stenophylla; Asteraceae; Flavonoids; Chemosystematic signi"cance

1. Subject and source

Aerial parts of the following voucher specimens were analysed: ¹. stenophylla: Mexico. Michoacan: Uruapan, C. G. Pringles 10361. Guerrero: Los Barrales, G. B. Hinton 14910. Jalisco: La Barranca, Guadalajara, W.E. Sa!ord 1460.

Voucher specimens are deposited in the Darwinian Herbarium (Buenos Aires, Argentina) and the Miguel Lillo Herbarium (TucumaHn, Argentina).

2. Previous work

None.

3. Present study

The following #avonoids were identi"ed in the aerial parts of ¹agetes steno

-phylla: quercetagetin, patuletin, patuletin 7-glucoside, isorhamnetin, isorhamnetin

(2)

3-galactoside and isorhamnetin 7-glucoside. The results were supported by all voucher specimens cited.

Separation and identi"cation of compounds were carried out by CC, PC, TLC and UV-VIS spectroscopy techniques, based on procedures described by Mabry et al. (1970) and by Markham (1982), and have been described in previous papers (Abdala de Israilev and Seeligmann, 1983; Abdala de Israiler et al. 1991)

4. Chemosystematic signi5cance

Morphology and #avonoid chemistry suggest that ¹_. _stenophylla _{is related to}

Argentine species. The #avonoids quercetagetin, patuletin and/or their glycosides, which characterise Argentine species of¹_agetes(Abdala, 1989), have also been found in this study.

¹. stenophyllamight be most closely allied to three north west Argentine species (Abdala and Seeligmann, 1983, 1985) where the#avonoid isorahmnetin and/or its glycosides, have also been detected.
