Chimonanthus praecox (L.) Link - syn. Calycanthus praecox L.; Chimonanthus fragrans Lindl. - Calycanthaceae \\
蜡梅 la mei (chin.), wintersweet, Japanese allspice, **(China-) Winterblüte**

"Shrubs or small trees, 3-13 m tall, deciduous or sometimes with persistent leaves... This species is cultivated throughout most of China as well as in other temperate areas of the world as a decorative plant, particularly for its sweetly fragrant flowers. The leaves, roots, flowers, and seeds are used medicinally. Because of its extensive and long cultivation in China, some of the reported distribution is uncertain as to it actually being native."

"Its strongly scented pendent flowers, produced in winter on bare stems, have 15-21 yellow tepals, the inner ones usually with purplish red pigments." [[https://en.wikipedia.org/wiki/Chimonanthus_praecox]]

"Wintersweet is a relative of Calycanthus, our familiar Sweet Shrub or Carolina Allspice, and the flowers of the two are similar in overall structure. Those of the Wintersweet, however, are usually only about an inch across, and the fifteen to twenty petal-like segments are a translucent yellow, the innermost ones heavily streaked and blotched with purple. Several varieties with slightly different flowers are occasionally encountered. Chimonanthus praecox var. grandiflorus has flowers almost twice the size of those of the typical plant, but they are only slightly fragrant. The flowers of the var. concolor (var. luteus) are entirely yellow, and they often are sparingly produced." \\

SPME was applied to sampling of the volatile compounds emitted from living Chimonanthus praecox L. flowers and excised Chimonanthus praecox L. flowers. Main components of the flower scent were linalool (36.0%), methyl salicylate (24.5%), phenylethanol (11.1%), benzyl acetate (5.9%), trans-linalool oxide (furanoid, 5.3%), α-phellandrene (4.7%), and 4-methyl-1,3-pentadiene (2.0%). Minor components were e.g. styrene (0.6%), benzaldehyde (0.4%, nerol (0.8%), phenylethyl acetate (0.7%), cinnamaldehyde (0.04%), phenylpropyl acetate (0.3%), and cinnamyl acetate (0.05%). \\
