Maxillaria tenuifolia Lindl. - Orchidaceae - delicate-leafed maxillaria, coconut pie orchid, Kokosnuss-Maxillaria, Kokosorchidee

Orchid, native to Central America.

„Of all the members of its genus, which are not as sought after in cultivation, Maxillaria tenuifolia is the most popular. It has rather small flowers, typically no more than one and a half inches, and they come only one to a spike. Its popularity is due to the flower's scent, which is just like that of coconuts. The flowers are colored in red with yellow or brown speckles.“

The typical coconut scent of M.tenuifolia flowers is produced primarly by δ-decalactone (29.5%), accompanied by γ-decalactone (1.0%), and a series of methyl ketones like 2-undecanone (2.9%), and 2-tridecanone (9.5%).

(R)-(+)-delta-decalactone (R=n-Pentyl)

Major constituents of M.tenuifolia flower volatiles are the sesquiterpenes α-copaene (35%) and β-caryophyllene (26%). Monoterpenes like α-pinene (5%), β-pinene (2%), myrcene (7%), limonene (3%), 1,8-cineole (4%) are also present, but the scent impression is dominated by δ-decalactone (0.4%).
