Codonopsis lanceolata (Campanulaceae) has been used in traditional medicines, as its roots contain several kinds of 3,28-bidesmosidic triterpenoid saponin with high medicinal values. In this study, we induced hairy root-derived transgenic plants of C. lanceolata and analyzed triterpenoid saponins from the leaf, stem and root. Transgenic plants were regenerated from the hairy roots via somatic embryogenesis. The saponins are lancemaside A, B and E, foetidissimoside A, and aster saponin Hb. Transgenic plants contained richer triterpenoids saponin than wild-type plants. Major saponin lancemaside A was the most abundant saponin in the stem from transgenic-plant, $4.76mg{\cdot}1^{-1}dry$ stem. These results suggest that transgenic plants of C. lanceolata could be used as medicinal materials for the production of triterpene saponins.

The studies on the saponins of Korean ginseng, Panax ginseng C.A. Meyer, were performed according to the cultivating locations, sampling seasons, plant parts, and growing stages. The changes in saponin content in the course of manufacturing Red ginseng and Ginseng extract were observed. In this paper, a new method for the determination of the total and the individual saponin glucosides was proposed and applied to the samples under study. The method employing Digital Densitorol DMU-33C (Toyo electric Co., Japan) followed the separation of the saponins by means of a preparative thin layer chromatography. The saponin contents and their fractional distribution were summarized as follows: 1. The average concentrations(% plant dry weight) of semi-purified saponins in the roots of Korean ginseng planted in the various locations were 5.0%(Keumsan), 6.0% (Kimpo), and 5.4% (Pocheon), respectively. 2. There were 3.3% saponins in White ginseng(Rhizome) and 12.7% saponins in Ginseng tail (Fibrous root). 3. Regarding the year of growth, the contents of saponins were 90.3mg (2-year-old ginseng), 254.4mg (3-year-old ginseng), 404.2mg (4-year-old ginseng). 999.6mg (5-year-old ginseng), and 1377.1mg (6-year-old ginseng) respectively, and the saponin factions containing panaxatriol as an aglycone increased. 4. Thin layer chromatography revealed that Red ginseng yielded many saponins which Shibata et al. designated as $ginsenoside-Rb_1$ (22.1%), $-Rb_2(15.4%)$, -Rc(12.6%), -Re (15.7%), and $-Rg_1$, (9.3%). 5. 29.9% of crude saponins were isolated from ethanolic extract of Panax ginseng fibrous root and their extraction yield was 94.2% of fibrous root saponin.

In the present study effects of 2,4-D and kinetin on the callus tissue growth of Korean ginseng(Panax ginseng C. A. Meyer), in relation to the synthesis of saponin were investigated. The saponin synthesis in the callus culture of ginseng root was enhanced by 2,4-D and kinetin. The total saponin content of callus grown on the optima growth conditions, that is, 5mg/l of 2,4-D and 2mg/l of kinetin, was about three times as high as that of the 6 year-old ginseng roots commercially used as herbs. The kinetin specifically increased the synthesis of protopanaxadiol group ginsenoside and decreased the syntehsis of protopanaxatriol gropu in callus cultures, while 2,4-D caused to an increase in the synthesis of protopanaxatriol group ginsenoside and decrease the synthesis of protopanaxadiol group.

The effects of Gypsophila saponin, sodium dodecylsulfate (SDS) and Triton X-100 on volume changes and fragility of red blood cells were compared to ginseng saponin to elucidate whether there are any difference in their action on membrane lipid. Cell volume was decreased to about 38% in 1M NaCl and increased to about 20% in 1/10M NaCl. Hematocrit value was decreased by Gypsophila saponin, SDS, and Triton X-100 which caused hemolysis in isotonic NaCl solution. These detergents also inhibited increase of cell volume and accelerated hemolysis in hypotonic solution. However, ginseng saponin did not influence to osmotic volume changes and hemolysis of red blood cells. These results suggest that the disruptive effect of plant saponin on membrane barriers induced by removing membrane lipid is different from their source and ginseng saponin has very low affinity to membrane lipid.

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.

Allium hookeri (Liliaceae) has been received the increasing attention as a bioactive resource due to its potent biological activities including anti-oxidant, anti-obesity, anti-microbial and lipid-regulating activities. The beneficial effects of A. hookeri are known contributed from the high content of organosulfur compounds in A. hookeri. Though a variety of articles demonstrated that A. hookeri contains 'saponin' as a bioactive constituent, the scientific evidence to prove it was limited. In the present study, we have attempted to identify saponin contained in A. hookeri through chromatographic isolation and NMR spectroscopic methods. As a result, a spirostane-type steroidal saponin (1) has been successfully isolated from the methanolic extract of A. hookeri roots. The structure of 1 was elucidated by extensive 1D and 2D spectroscopic methods including ¹H-NMR, ¹³C-NMR, ¹H-¹H COSY, HSQC, HMBC and NOESY; identified as (3β, 22R, 25S)-spirost-5-en-3yl O-6-deoxy-α-L-mannopyranosyl-(1→4)-O-6-deoxy-α-L-mannopyranosyl-(1→4)-O-[6-deoxy-α-L-mannopyranosyl-(1→2)]-β-D-gluco pyranoside. 1 showed the significant inhibitory activity on mushroom tyrosinase with IC₅₀ values of 248.7 μM while the inhibition on alpha-glucosidase was not significant.
