Object To study the chemical constituents of Acanthopanax gracilistylus W.

Four known oleanane glycosides were isolated for the first time from the MeOH extract of the leaves of Acanthopanax sieboldianus forma albeofolium Yook by using column chromatography.

OBJECTIVE To develop an RP-HPLC method to determine chlorogenic acid in Cortex Acanthopanacis giraldii,Cortex Acanthopanacis senticosus and Cortex Periplocae.

In vivo tissue distribution of Age protein from Cortex Acanthopanacis in normal and tumor-bearing mice;

Identification of Cortex Periplocae and Cortex Acanthopanacis by near infrared and generalized two-dimensional correlation spectroscopy;

The oscillating fingerprints of ten kinds of herbal medicines such as ortex eucommiae,cortex meliae,radix isatidis,cortex magnoliae officinalis,cortex albiziae,cortex lycii,cortex acanthopanacis,herba andrographitis,cortex fraxini,and rhizoma acori tatarinowii were abtained using the "BrO~-_3-Mn~(2+)-H~+-acetone" oscillating system.
