ABSTRACT
Objective To analyze and identify the chemical constituents of essential oil from the fruits of Cinnamomum camphora chvar. Borneol. Methods The essential oil from the fruits was extracted by steam distillation and its chemical constituents were analyzed and identified by GC-MS. Results Fifty compounds were separated, and 42 kinds of which accounting for 99.536% were identified. D-borneol was the most abundant compound, of which the amount was 50.684%of the total constituents. Conciusion This present study demonstrated higher content of natural D-borneol, providing scientific basis for further exploration and utilization of the fruits of Cinnamomum camphora chvar. Borneol.
ABSTRACT
<p><b>OBJECTIVE</b>To optimize the condition of callus of Cinnamonum camphora induced.</p><p><b>METHOD</b>GC and plant tissue culture method were applied in the study.</p><p><b>RESULT</b>The effect of callus induced and the growth of callus were different in MS medium with different proportion of hormone. The ration of callus induced was the highest and the growth of callus was the most prosperous in the MS medium with 4 mg x L(-1) 2,4-D and 0.2 mg x L(-1) 6-BA. It is found that callus induced by young leaf contained borneol, but callus induced by young stem not.</p><p><b>CONCLUSION</b>The optimization of callus of C. camphora induced is using the MS medium with 4 mg x L(-1) 2,4-D + 0.2 mg x L(-1) 6-BA. Callus induced by young leaf can generate borneol.</p>
