Anthriscus sylvestris (L.) Hoffm. - Apiaceae - cow parsley, wild chervil, Wiesen-Kerbel

Biennial or perennial herb, up to 1.50m tall, native to Eurasia, naturalized in North America.

Cow parsley has a harsher flavor than garden chervil, with a hint of carrots. Young leaves are used to flavor salads, cottage cheese, wild herb soups, and wild vegetables. http://de.wikipedia.org/wiki/Wiesen-Kerbel

Main volatile compounds of the floral fragrance of A. sylvestris, collected at PorapakQ, were myrcene (47%), δ-3-carene, γ-cadinene, E/Z-β-ocimene, γ-terpinene, β-phellandrene, limonene and γ-elemene.

„The volatile components of fresh leaves and roots from Anthriscus sylvestris (L.) Hoffm., obtained through hydrodistillation, were analysed by GC and GC-MS. This was compared to dichloromethane extracts of both fresh and dried leaf and root material. The monoterpene fraction (69-70%) dominated, while β-phellandrene (39-45%) was the main component in both the leaf and the root oil. Other components in the leaf oil were β-myrcene (17%), sabinene (6.2%), Z-β-ocimene (5.4%) and benzene acetaldehyde (phenylacetaldehyde, 4.1%). In the roots we found Z-β-ocimene (16.9%) and α-pinene (4.6%) as other major components. These principle constituents of both essential oils were also present in the dichloromethane extracts of the fresh and dried leaves and the roots, although in much smaller percentages. Comparing hydrodistillation of fresh plant material with a dichloromethane extract, the latter yielded a considerably lower amount of constituents.“

The main compounds of three essential oil samples obtained by steam distillation from the rhizomes of Anthriscus sylvestris (L.) Hoffm. growing in Quebec (Canada), were β-phellandrene (25.1-66.4%), myrcene (8.7-48.4%), trans-sabinyl acetate (tr-5.6%) and cis-β-ocimene (2.6-4.4%). The hydrolates contained mainly trans-sabinyl acetate, tiglic acid, carvacrol, 3-methyl-2(5H)-furanone, terpinen-4-ol and elemicin.
