Analysis of Chemical Constituents in Volatile Oils from Glechome Longituba (Nakai) Kupr. in Zhejiang Province

OBJECTIVE To study the chemical constituents of volatile oils from Glechome longituba （Nakai） Kupr. in Zhejiang province. METHODS The volatile oils were extracted by steam-stilling and were identified by GC-MS. Calculated the percentage composition of the volatile oils according to peak area normalization method. RESULTS Thirty-three compounds were identified. The major constituents of volatile oils were caryophyllene and caryophyllene oxide（25.14%）, prococene
Ⅰ and Ⅱ（12.58%）, viridiflorene（10.6%）, isopinocamphone（10.5%）, β-cubebene（6.34% ）, and （-）spathulenol（4.53%）, γ-elemene（4.68%）, β-elemene（1.45%） and D-limonene（0.39%） could also be found in volatile oils. CONCLUSION The volatile oils of Glechome longituba （Nakai） Kugr. groun in Zhejiang province contained abundant active medicinal ingredients.
