Abstract

To quantitatively analyze volatile oil in curcuma kzoangsiensis S. G. Lee C. F. Liang. produced in different places and seasons, and to quantitatively analyze crucumol by gas chromatographic (GC). The volatile oil was distilled by the steam distillation(XD) and the crucumol was determined by GC on a HP-5 column (0.32 mm!`30m, 0.2|m), Inlet
-1 temperature 200!aC, FID 250!aC, flow 1.0 ml!/ , splitless. Temperature programming started at 60!aC holding for 4
-1 min, then increased to 210!aC at a rate of 3!aC!/ . The quantity of volatile oil in Curcuma kzoangsiensis S. G. Lee C. F. Liang. in different places and collecting time were detected. The contents of volatile oil and crucumol was the hightest
in Bingyang place. The quantity of volatile oil was the richtest in January and February, and the same result was
obtained for crucumol. As a result, January and February was the best time for the collection of Curcuma kzoangsiensis
S. G. Lee C. F. Liang.. The contents of volatile oil and crucumol should be taken as a standard for the evaluation of the quantity 0f curcuma phaeocaulis val.. and the determination of its collecting time.
