"The ashoka is prized for its beautiful foliage and fragrant flowers. It is a handsome, small, erect evergreen tree, with deep green leaves growing in dense clusters." [[http://en.wikipedia.org/wiki/Saraca_asoca|wikipedia]]

"Many legends, cultural and scientific, were connected with asoka but as a medicinal tree against female diseases was not thoroughly recognised before the ninth century of our era... According... to Hiuen-Tsang the Buddha was born under a asoka tree." \\

The flower scent of ashoka is "...very diffusive and far-reaching, it brings to mind a delightful combination of lily and freesia, accompanied by a shade of orange blossom." \\
Although the scent, trapped on Porapaqk SQ, contained mainly (E,E)-farnesene (49%) and (E)-ocimene (29%), "...the very crisp and clean lily note is due to the combination of benzyl salicylate with prenyl salicylate, (Z)-hex-3-enyl salicylate, and (Z)-1-methylhex-3-enyl salicylate, all charcaterized by very low odor treshold values... (Z)-1-Methylhex-3-enyl salicylate... is characterized by a very appealing transparent and crisp floral-green odor. It is of basic importance - in combination with the salicylates mentioned above, β-ionone, jasmone, methyl anthranilate, and 1H-indole - to the flower scent of Saraca indica." \\
