Glucosides in Paeoniae Radix, paeoniflorin, albiflorin, oxypaeoniflorin and benzoylpaeoniflorin were quantitatively analysed simultaneously by TLC-densitometric method using a dual wavelength TLC scanner. In 12 samples collected in Hokkaido, Nara prefecture and China, the glycosides, paeoniflorin, albiflorin, oxypaeoniflorin and benzoylpaeoniflorin were found to be presents in amounts ranging 1.96-4.12%, nd-1.39%, 0.08-0.21% and 0.04-0.21%, respectively. Paeoniflorin was found to be present in the root cortex and pith in amount of 2.54% and 1.77%, respectively, and albiflorin was detected only in the cortex. The highest content of paeoniflorin was found in the top of root (3.93%) and the lowest in the lower part of main root (1.66%). Oxypaeoniflorin was found to have the same tendency as paeoniflorin. Little albiflorin was contained in the top of root. Paeoniflorin and albiflorin in KAWASARI and YUDOSHI were less than those in KAWATSUKI, and the albiflorin content in YUDOSHI was less than one-half of that in KAWATSUKI.
