Abstract
Grindelia robusta (Asteraceae)is a perennial species, native of California, employed in pharmaceutical manufacture since recent studies reported antitussive, expectorant, sedative, and analgesic effects of the plant essential oil fractions. During the 2007 spring phytoplasmas belonging to ribosomal subgroup 16SrI-B (Aster yellows, ‘Candidatus Phytoplasma asteris’) was identified in G. robusta showing virescence and phyllody symptoms. In the order to verify possible qualitative differences in the composition of essential oils from healthy and phytoplasma infected G. robusta plants, gas chromatography-mass spectrometry (GC-MS) analyses was performed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
