Abstract: | Summary The flavonoid glycosides and the biflavonoids of cypress leaves have been separted by means of high-performance thin-layer chromatography with quantitation by densitometry. Some flavonoid glycosides and biflavonoids have been identified, other than from their chromatographic characteristics, by means of UV spectra recorded directly on the layer. Different clones, resistant and susceptible to cypress canker, have been analyzed; some differences between these two classes of trees have been found in their biflavonoid content. |
