  • 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.

  • A new oleanane-type triterpenoid saponin together with six known saponins were isolated from the roots of Pulsatilla cernua. Their structures were elucidated on the basis of spectroscopic data, including 2D NMR spectra and chemical evidence. Compounds 1 and 6 are reported from this genus for the first time.

  • Bioassay-guided fractionation has led to the isolation of triterpenoid saponins such as Acutoside A (3-O-[O-${\beta}$-D-glucopyrano$yl-(1${\to}$2)-O-${\beta}$-D-glucopyranosyl] oleanolic acid) from the whole plants of Viola hondoensis. Among them, Saponin 1 exhibited potent inhibitory activity against matrix metalloproteinase (MMP)-1, and prevented the UV-induced changes in the MMP-1 expression. In addition, compound was isolated from this plant for the first time.

  • Codonopsis lanceolata (Campanulaceae) has been used in traditional medicines, as its roots contain several kinds of triterpenoid saponin with high medicinal values. In this work, we induced transgenic hairy roots of C. lanceolata and analyzed triterpenoid saponins from the hairy roots and hairy root-derived transgenic plants. Hairy roots were obtained from leaf explants by the transformation of Agrobacterium rhizogenes R1000. Transgenic hairy root lines were confirmed by the transcriptional activities of rolA, B, C, and D genes by RT-PCR. Transgenic root lines actively proliferated on hormone-free medium but not in nontransformed roots. Hairy roots contained richer triterpenoids (lancemaside A, foetidissimoside A, and aster saponin Hb) than nontransformed roots. Transgenic plants were regenerated from the hairy roots via somatic embryogenesis. They showed phenotypic alterations such as shortened shoots and an increased number of axillary buds and adventitious roots. The transgenic plants also contained higher triterpenoid levels than wild-type plants. These results suggest that hairy roots and transgenic plants of C. lanceolata could be used as medicinal materials for the production of triterpene saponins.

  • Two triterpenoid saponine were isolated from the stems of Acer ginnala Maxim. The structures of triterpenoid saponins were established as ilexoside O, $3-O-{\alpha}-L- rhamnopyranosyl(1{\rightarrow}2)-{\beta}-D-glucopyranosyl(1{\rightarrow}2)-{\beta}-D-xylopyranosyl-pubescenolic$ acid 28-{\beta}-D-glucopyranosyl$ ester(1) and ilexoside K, $3-O-{\beta}-D-glucopyranosyl(1{\rightarrow}2)-{\beta}-D-xylopyranosyl-pubes-cenolic$ acid $28-{\beta}-D-glucopyranosyl$ ester(2). Their chemical structures have been elucidated on the basis of spectral methods.

  • Certain steroids and triterpenoids isolated from diverse plant families were known to posses anti-inflammatory activity. In the course of finding new anti-inflammatory natural products, some steroidal and triterpenoid saponins were isolated and evaluated for their anti-inflammatory activity using in vivo mouse ear edema test. At the oral dose of 100 mg/kg, several steroidal saponins and triterpenoid saponins such as hederagenin glycosides showed significant inhibition of ear edema (20∼37% inhibition), though less potent than indomethacin and hydrocortisone.

  • The roots of Codonopsis lanceolata (Campanulaceae) contain several kinds of triterpenoid saponin with high medicinal values, which have been used in traditional medicines. This study investigates the impacts of methyl jasmonate (MeJA) - adding time on the saponin synthesis and the hairy root growth of C. lanceolata. A significant decrease in major saponin (lancemaside of three kinds) content of hairy roots was observed with MeJA treatments. Contents of lancemaside A, B and E decreased about 15% more than non-treated hairy roots. In contrast, minor saponin (foetidissimoside A and aster saponin Hb) accumulation was about 15% higher than the non-treated hairy roots. These results suggest that MeJA treatment could be used in the production of teriterpene saponins.

  • Effects of modifier and soaking on extraction of triterpenoid saponin (glycyrrhizin) from liquorice were examined using supercritical $CO_2(SC-CO_2)$ at 50 MPa, $60^{\circ}C$, and flow rate of 3 mL/min, and glycyrrhizin content was analyzed by HPLC. Additon of undiluted methanol, ethanol or isopropanol as modifier to $SC-CO_2$ had little influence on extraction yield of glycyrrhizin. Soaking process using water increased the extraction yield as the sample to solvent ratio was increased. Addition of 70% methanol, ethanol or isopropanol to $SC-CO_2$ significantly increased the extraction yields, with 70% methanol resulting in the highest yield. When water at 90% (w/w) of sample weight was used for soaking, the extraction yield and rate increased, 70% ethanol-modified $SC-CO_2$ was almost equal to that obtained using 70% methanol.

  • Several triterpenoid saponins from root of Pulsatilla koreana Nakai (Ranunculaceae) were studied and their biological activities were reported. It is difficult to analyze triterpenoid saponins using HPLC-UV due to the lack of chromophores. So, evaporative light scattering detection (ELSD) is used as a valuable alternative to UV detection. More recently, a charged aerosol detection (CAD) has been developed to improve the sensitivity and reproducibility of ELSD. In this study, we developed and validated a novel method of high performance liquid chromatography coupled with a charged aerosol detector for the simultaneous determination of four triterpenoid saponins: pulsatilloside E, pulsatilla saponin H, anemoside B4 and cussosaponin C. Analytes were separated by the Supelco Ascentis$^{(R)}$ Express C18 column (4.6 mm ${\times}$ 150 mm, 2.7 ${\mu}m$) with gradient elution of methanol and water at a flow rate of 0.8 mL/min at $30^{\circ}C$. We examined various factors that could affect the sensitivity of the detectors, including various concentrations of additives, the pH of the mobile phase, and the CAD range. Linear calibration curves were obtained within the concentration ranges of 2 - 200 ${\mu}g$/mL for pulsatilloside E, anemoside $B_4$ and cussosaponin C, and 5 - 500 ${\mu}g$/mL for pulsatilla saponin H with correlation coefficient ($R^2$) greater than 0.995. The limit of detection (LOD) and quantification (LOQ) were 0.04 - 0.2 and 2 - 5 ${\mu}g$/mL, respectively. The validity of the developed HPLC-CAD method was confirmed by satisfactory values of linearity, intra- and inter-day accuracy and precision. This method could be successfully applied to quality evaluation, quality control and monitoring of Pulsatilla koreana.
