Figure 5.4 GALDI mass spectra of ursonic acid (7, m/z 477) fresh (a), photoaged with (b) and without (a) glass filter. Spectrum (b) depicts the normal ageing pattern (cf. Figure 5.3), but ageing without glass filter and therefore with much more UV light results in a mass shift of (M+2) in spectrum (c) relative to (b), which is explained by Norrish reactions...

Arctostaphylos uva-ursi (bearberry) contains a steroid, sitosterol, and triterpenoids, such as amyrin, betulinic acid, lupeol, oleanolic acid, taraxenol, ursolic acid, and uvaol. The main constituent is a glucoside called arbutin. Other constituents are methylarbutin, ericolin, ursone, gallic acid, and ellagic acid. [Pg.1235]
