Physalis peruviana L. - Solanaceae - Cape gooseberry, Kapstachelbeere, Andenkirsche
Perennial herb, 0.5-2m tall, native to South Africa, naturalized in South America, cultivated worldwide.
„The volatile constituents of cape gooseberry (Physalis peruviana L.) were characterized using liquid/liquid extraction and fractionation of the flavour concentrates on silica gel, followed by high resolution gas chromatography and coupled gas chromatography — mass spectrometry. Sniffing gas chromatography of serially diluted flavour extracts showed methyl 2-methylbutyrate, 2,5-dimethyl-4-hydroxy-(2H)-furanone and its 4-methoxy derivative, 4- and 5-octanolide, β-ionone, and β-damascenone to be impact components. The non-volatile flavour fraction contained glucose, fructose, sucrose, citric acid, and smaller amounts of organic aliphatic and benzoic acids. The bound forms of volatiles were dominated by benzyl alcohol, 2-methylpropanol, and 2-methyl-butanol. The presence of significant amounts of activated acyl moieties in the fruit was indirectly concluded from various data.“
