 "...edible, berry or grape-sized fruit similar to kiwifruit in taste and appearance, but are green, brownish, or purple with smooth skin, sometimes with a red blush. Often sweeter than the kiwifruit, hardy kiwifruit can be eaten whole and need not be peeled."

-"More than 240 compounds were detected when the volatile components of the flowers and the fruit from several Actinidia arguta genotypes were investigated. Around 6070 different compounds were extracted from individual tissues of each genotype. Two different methods of volatile sampling (headspace and solvent) favoured different classes of compounds, dependent upon their volatilities and solubilities in the flower or fruit matrices. The compounds extracted from flowers largely comprised linalool derivatives including the lilac aldehydes and alcohols, 2,6-dimethyl-6-hydroxyocta-2,7-dienal, 8-hydroxylinalool, sesquiterpenes, and benzene compounds that are presumed metabolites of phenylalanine and tyrosine. Extracts of fruit samples contained some monoterpenes, but were dominated by esters such as ethyl butanoate, hexanoate, 2-methylbutanoate and 2-methylpropanoate, and by the aldehydes hexanal and (E)-2-hexenal. A number of unidentified compounds were also detected, including 8 from flowers that are so closely related that they are either isomers of one compound or two or more closely related compounds. This is the first report of the presence of a range of linalool derivatives in Actinidia." \\+"More than 240 compounds were detected when the volatile components of the flowers and the fruit from several Actinidia arguta genotypes were investigated.

 Major compounds of the glycosidically bound volatile fraction of baby kiwi (Actinidia arguta) were 2,5-dimethyl-4-hydroxy-3(2H)-furanone (furaneol), benzyl alcohol, 3-hydroxy-β-damascone, hexanal, and (Z)-3-hexen-1-ol. "Eugenol, raspberry ketone, and 4-vinylguaiacol were identified for the first time in the fruit of an Actinidia species. The high concentration of 2,5-dimethyl-4-hydroxy-3(2H)-furanone in bound form (95.36 μg/kg) is particularly interesting and justifies further investigation." \\ Major compounds of the glycosidically bound volatile fraction of baby kiwi (Actinidia arguta) were 2,5-dimethyl-4-hydroxy-3(2H)-furanone (furaneol), benzyl alcohol, 3-hydroxy-β-damascone, hexanal, and (Z)-3-hexen-1-ol.

 +Headspace volatiles of picked flowers collected with SPME (DVB/CAR/PDMS) and GC-MS showed 2-/3-methylbutanol (1.5-49.4%), 6-methyl-5-hepten-2-one (0-4.9%), lilac aldehydes B/C/D (1.0-53.0%), linalool (0-22.8%), lilac alcohols C/D (15.3-44.2%),  E)-β-ocimene (0-7.0%), 2-(4-methoxyphenyl)ethanol (0-21.%), 2-phenylethanol (0.2-25.0%), and 3-methylbutyl 3-methylbutanoate (0-3.3%) as main components. \\
