Studies on Chemical Constituents of Essential Oil from Leaves of Jiang-Zhang

Zhu Liang-fang, Lu Bi-yao and Li Yu-jing   

Abstract: Jiang-Zhang is a Physiological type of Cinnamomum porrectum (Roxb.) Kosterm. The essential oil of leaves of Jiang-Zhang can be extracted by steam distillation, with yields of 0.5–0.8%. It contained dtral (α-,β-citral) 64.11% and can be used in aromatic and medicinal industries. We used the methods of GC, IR, GC/MS/DS and prepared derivative and 47 chemical constituents were identified, as follows: α-thujene (0.06 %), α-pinene (2.42%), camphene (1.26%), sabinene (0.21%),β- pinene (1.38%) myrcene(0.38%), α-phellandrene (0.32%),△3-carene (0.01%), p-cymene(0.21%),α-limonene (1.57%), 1 8-cineole (0.82 % ), β-phellandrene (0.10 %), cis-linalool oxide(0.07 % ), linalool (8.43 % ) epicamphor(0.26 % ), camphor(1.10 %), borneol( 1.07 % ), β-citral (neral) (28.28 % ), geraniol (0.25%), nerol (0.47%), α-citral (geranial) (35.83%), methyl citronellate (0.12%), n-undecane (0.18), safrole (0.02), methyl geranate (0.23%), geranyl formate (0.09%), α-copaene (0.12%), trans-methyl cinnamate (0.02%), n-dodecane (0.20), β-elemene (0.12%), caryophyllene (4.67%), α-guaiene (0.04), β-guaiene (0.06%), β-selinene (0.97%), azulene (0.38%), β-cubebene (0.30%), n-pentadecane (0.05%), β-gurjunene (0.04 %), epi-β-santalene (0.46 %), aremophliene (0.05 % ), alloaromadendrene (0.03 % ), α-elemene (0.26%), trans-β-farnesene (0.04%), (z)-β-farnesene (0.30%), r-elemene (0.03%), β-bisaboiol(0.41%), cedrol (0.16%), respectively.
