Bursera delpechiana Poiss. ex Engl. - syn. Bursera linanoe (La Llave) Rzed., Calderón & Medina; Amyris linaloe La Llave - Burseraceae \\
Indian lavender tree, Mexican Linaloe tree, **Indischer Lavendel-Baum**, Linaloe-Baum

Deciduous tree, native to Mexico, cultivated in India. 
 
"B.linanoe is a narrow endemic to the tropical dry forest in the south of Mexico in the states of Puebla, Oaxaca, Guerrero and Morelos (Becerra & Venable, 2008)... Introduced to india from Mexico at the beginning of the 20th century for the exploitation of its essential oil... Bursera delpechiana did well in the Indian environment due to its drought resistance and its cultivation spread soon to andhra Pradesh, Thailand, and other areas. The innovation of distilling the mature fruits instead of the wood, as it had been done in Mexico, proved to be a success, giving the indian oil a superior odor and a longer persistence. The indian oil eventually took over the international markets and its industrial exploitation in Mexico collapsed." \\
Comparing the chemical composition of essential oils of Bursera delpechiana from Mexico and B. linanoe from India show (B.delpechiana/B.linaloe) linalool 2.20/0.16%, linalyl acetate 90.34/92.16% and germacrene D 1.96/0.72% as main components. \\

Essential oil obtained by steam distillation of the leaves and fruits contains more linalyl acetate than linalool; oil from the branches is the other way round. When stored for more than 12 months, cis- and trans-linalooloxide are formed. \\

(R)-(-)-linalyl  acetate (~95% ee; 57.6%), (S)-(-)-germacrene D (100% ee; 39.3%) and β-caryophyllene (1.8%) were the main components of B.linaloe leaf extract with dichloromethane. Linalool was found only as a trace (<0.1%). \\
