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, 4-hydroxy-2,5-dimethyl-3(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.“
[The flavour of cape gooseberry (Physalis peruviana L.), Berger, R. G., Drawert, F., Kollmannsberger, H. Zeitschrift für Lebensmittel-Untersuchung und Forschung, Vol.188(2), 1989, 122-126]

Major volatile components of ripe cape gooseberry fruit pulp (headspace SPME) were hexanol (6.8%), 1,8-cineole (6.6%), ethyl butanoate (6.4%), ethyl octanoate (4.0%), ethyl decanoate (3.3%), 4-terpineol (3.2%), 2-methyl butanol (3.1%), benzaldehyde (2.9%), butanol (2.5%), dimethylvinylcarbinol (2.2%), 2-methylbutyl acetate (2.1%), butyl butanoate (2.1%), and benzyl alcohol (2.0%). Among the minor components were e.g. rose oxide (0.13%), δ-octalactone (0.59%), and β-ionone (0.19%).
