| "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."

| "A novel rapid, simple and solvent-free method was developed for determination of the volatile compounds from the flowers of Chimonanthus praecox Link using headspace solid-phase microextraction (HS-SPME) and gas chromatography-mass spectrometry (GC-MS). The SPME conditions were firstly optimized and applied to sampling of the volatile compounds emitted from living Chimonanthus praecox L. flowers and excised Chimonanthus | "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." \\ |
| praecox L. flowers. Thirty-one compounds emitted from living flowers were identified for the first time, which mainly included 4-methyl-1,3-pentadiene (2.0%), α-phellandrene (4.7%), benzyl methanol (11.1%), trans-linalool oxide (furanyl ring) (5.3%), α-linalool (36.0%), methyl salicylate (24.5%) and acetic acid benzyl ester (5.9%). Comparing the emission from living flowers and excised flowers, twenty-eight compounds were found to be detected in the two emissions, and three compounds, n-pentadecane, n-cetane and n-heptadecane, were only | [Winter blooming shrubs.

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%). \\ |
