 "The woodland strawberry was first cultivated in ancient Persia where farmers knew the fruit as Toot Farangi. Its seeds were later taken along the Silk Road towards the far East and to Europe where it was widely cultivated until the 18th century, when it began to be replaced by the garden strawberry, (Fragaria × ananassa), which has much larger fruit and showed greater variation, making them better suited for further breeding."  [[http://en.wikipedia.org/wiki/Fragaria_vesca]] "The woodland strawberry was first cultivated in ancient Persia where farmers knew the fruit as Toot Farangi.

 +Sensory experiments with reconstituted wild strawberry flavor preparations showed that 2,5-dimethyl-4-hydroxy-3(2H)-furanone (first found by Sundt 1970) makes a great contribution to the flavor of the berries. Analysis of ether/pentane extracts of F.vesca and F.×ananassa cv. Senga Sengana showed concentrations of 1.7mg/kg (F.vesca; with 10.7% main volatile component) and 0.2mg/kg (F.vesca and ×ananassa cv. Senga Sengana). Most abundant esters of both extracts were methyl butyrate, ethyl butyrate, ethyl hexanoate, hexyl acetate, and (2E)-hexenyl acetate. Major volatiles of F.vesca were acids like acetic acid (8.9%), hexanoic acid (5.1%), and butyric acid (3.9%) as well as alcoholes like (2E)-hexenol (4.1%), hexanol (3.0%), benzyl alcohol (2.7%), 2-pentadecanol (1.7%), and eugenol (1.6%). Major volatiles of F.×ananassa cv. Senga Sengana were also acids like hexadecanoic acid, hexanoic acid, 2-methylbutanoic acid, butanoic acid, acetic acid, and cinnamic acid, as well as alcoholes like hexanol, (2E)-hexenol, and linalool. Both extracts contained methyl cinnamate, but only F.vesca contained methyl anthranilate and methyl N-formyl anthranilate. Small amounts of vanillin, γ-hexalactone, γ-heptalactone, and γ-octalactone were present only in F.vesca, whether δ-hexalactone, δ-octalactone, benzaldehyde, 2-methoxy-4-vinylphenol, 4-vinylphenol (0.05mg/kg F.×ananassa cv. Senga Sengana!), and eugenol were found in both extracts. \\

 "The wood strawberry Fr.vesca L. differs from the cultivated types in that it contains a very aromatic, plainly recognizable woodstrawberry-like semivolatile compound. It was identified as [[http://www.thegoodscentscompany.com/data/rw1008212.html|methyl anthranilate]], reported previously by Hirvi and Honkanen (1982). This component was detected first in the nearly 50-year-old 'Mieze Schindler'." \\ "The wood strawberry Fr.vesca L. differs from the cultivated types in that it contains a very aromatic, plainly recognizable woodstrawberry-like semivolatile compound.
