To develop a clinically available saponin- or sapogenin complex from Oriental medicines, the EtOH extract (KPRG-A) was obtained by extracting from the four crude drugs, Kalopanacis Cortex, Platycodi Radix, Rubi Fructus and Glycyrrhizae Radis. The BuOH fraction (KPRG-B), a crude saponin complex, was prepared by fractionating KPRG-A, which were further completely hydrolyzed to afford the sapogenin complex (KPRG-D). In an attempt to find the antinoicpetive effects of the saponin complex and sapogenin complex, KPRG-C, and -D, were assayed by writhing-, hot plate-, and tail-flick tests using mice or rats. The three samples were also subjected to antiiflammatory tests using serotonin-induced and carrageenan-induced hind paw edema mice and rats, respectively. The three samples significantly reduced inflammations and pains of the experimental animal. The potency were found in the order of KPRG-D> KPRG-C> KPRG-B. The most active sample, KPRG-D, caused no death, no body increase or no anatomical pathlogic change even at 2,000 mg/kg dose. These results suggest that a sapogenin complex, KPRG-D, which was found to contain mainly hederagenin, platycodigenin, polygalacic acid, 23-hydroxytormentic acid, glycyrrhetic acid together with minor triterpene acids, could be a potential candidate for antiinflammatory therapeutics.

From crude drug preparation(Soshiho-Tang) ginseng sapogenins were identified by TLC and $ginsenoside-Rb_1$ was determined quantitatively by HPLC. Panaxadiol, pandaxatriol, acid-hydrolysates of ginseng saponin, were identified by TLC with benzene/acetone(4 : 1, v/v). Rf values of which were measured as 0.26 and 0.14, respectively. The content of $ginsenoside-Rb_1$ was determined by HPLC on $Lichrosorb-NH_2$ column with $CH_3CN/H_2O/n-BuOH$(80 : 20 : 10, v/v). Its recovery rate in the extract granules, was as relatively low as $19.8{\pm}1.4%$ compared to the content in raw red ginseng.

The extract of Platycodi radix has long been used as an anti-inflammatory traditional medicine in Korea for the treatment of bronchitis, asthma and acute respiratory disease. In this study, the anti-inflammatory actions of the methanol extract of Platycodi radix administered via oral administration were evaluated. The results revealed that the extracts exhibited potent anti-inflammatory action. Of the hexane, chloroform, ethyl acetate, butanol and water fractions, the butanol fraction had the most potent anti-inflammatory action. Additioinally the sapogenin obtained through acid hydrolysis of the butanol fraction did not show anti-inflammatory action. These findings confirm the value of Platycodi radix as a traditional Korean medicine.

From the crude saponin obtained from the pods of Gleditschia officinalis seven spots were identified by TLC and quantity of gleditschia B was the highest among them. Ten kinds of prosapogenins were identified from the partial hydrolysates of crude saponin and found that prosapogenin E contain oleanolic acid as a sapogenin and prosapogenin F does echinocystic acid as the sapogenin. Hydrolysis of crude saponin yield glucose and rhamnose and the same sugar were also identified from the mixture of prosapogenin E and F.

The content and composition of saponin compounds of Panax species were analyzed according to their species, region and processing type of red and white ginseng. The species employed were Korean-, Chinese-, Japanese red ginsengs, and Korean white ginseng of Panax ginseng, American- and Canadian ginsengs of Panax quinquefolium, and Panax notoinseng. Twelve main saponin components in the ginseng were identified and quantified using TLC and HPLC. All three species had remarkably different content and composition. However, within each species they were similar. Twelve major ginsenosides were determined in P. ginseng, eight in p. quinquefolium, and six in P. notoginseng. Of the components of P ginseng Rf, $Rh_1$, $Rh_2$ and Ra were not detected in P quinquefolium, and $Rb_2$, Rc, Rf, $Rh_2$, Ra and Ro not detected in P. notoinseam. Crude saponin content and protopanaxadiol/protopanaxatriol saponin ratio were compared. They were 4.81~5.24% and 1.27~ 1.45 in p. ginsengs, 7.01~7.25% and 2.12~ 2.15 in p. quinquefolium, 9.80% and 0.99 in P. notoineng. The prosapogenin and sapogenin content were different among the Panax species.
