| The timber is used for furniture and sieve hoop-making, and in bridge construction. The leaves are used as a vegetable in China and Malaysia, and as animal fodder in India. The trees are widely used medicinally, with the bark being used as an astringent and depurative, powdered root as a refreshment and a diuretic, and tender leaves as a carminative." \\ | The timber is used for furniture and sieve hoop-making, and in bridge construction.

| "The young leaves of T. sinensis (xiāngchūn) are extensively used as a vegetable in China; they have a floral, yet onion-like flavor, attributed to volatile organosulfur compounds."

| The volatiles of the leaves of T.sinensis were analyzed with MAE-HS-SPME/GC-MS, and 45 compounds were identified (96% of the total chromatographic area). Trans-caryophyllene (21.4%), 2-hexenal (14.6%), 5-ethylthiazole (7.5%), 2,5-dimethylthiophen (4.2%), 1-methylimidazole-2-thione (3.6%), limonene (3.5%), β-eudesmol (2.6%), 1,7,7-trimethyl-2-vinylbicyclo[2.2.1]hept-2-ene (2.6%), 2-carene (2.3%), α-caryophyllene (2.1%) and β-elemene (1.9%) were the main components. Several kinds of low concentration terpenes and sulfur compounds like β-cedrene (1.5%), α-guaiaene (1.3%) and mintsulfide (0.2%) were also present. \\ | The volatiles of the leaves of T.sinensis were analyzed with MAE-HS-SPME/GC-MS, and 45 compounds were identified (96% of the total chromatographic area).

| "The various parts tissues of this species are widely used in Traditional Chinese Medicine (TCM). The leaves and stems of this plant were used for the treatment of itch, dysentery, and enteritis. The bark was used as an astringent and depurative, the powdered roots were used as a corrective, and the fruits were used as an astringent and for the treatment of eye infections. Previous phytochemical investigations on this species have resulted in the isolation of flavonoids, phenolics, alkaloids, terpenes, anthraquinones, and limonoids. Besides its uses in TCM, the young leaves of T. sinensis (xiāngchūn) have been used extensively as a vegetable source in China for their special onion-like flavor and wealth of nutrients such as carotene and vitamins B and C, etc. The cultivated variety with red young leaves (Figure 1a) is considered of better flavour than those with green leaves." \\ | "The various parts tissues of this species are widely used in Traditional Chinese Medicine (TCM).
