Abstract:
OBJECTIVETo study characteristic fingerprints of the fat-soluble components of different Marsdenia tenacissima samples by GC and GC-MS.
METHODThe sample was split in the 280 degrees C injection port, with 10:1 split ratio, and separated on a fused silica capillary column (DB-5, 30 m x 0.25 mm I. D., 0.25 microm film). The temperature program was 70 degrees C for 5 min, 8 degrees C x min(-1) to 200 degrees C, then 5 degrees C x min-1 to 260 degrees C, 260 degrees C for 10 min. The high pure nitrogen was used as a carrier gas, The FID temperature was 300 degrees C.
RESULTThere are 15 common peaks in the GC fingerprints of M. tenacissima and they are identified by GC-MS. The analyses on cluster and similarity degree of the finger the crude drugs from various habitats have been performed.
CONCLUSIONThe method has good repeatability. The GC fingerprint combined with the HPLC fingerprint of M. tenacissim can be used to evaluate its quality integrally.
