Saponin is one of major conponents in oriental medicine, which':s present in Ophiopogoneae. Saponin composition on ethyl acetate fractions from the butanolic extracts of two species, Liriope platyphylla and Ophiopogon japonicus was measured using high performance liquid chromatography (HPLC). HPLC analysis revealed that spicatoside A and B were identified in the tuber of L. platyphylla. However, spicatoside A was not identified in the tuber of O. japonicus. Related to that, it may be possible to discriminate between Liriopis and Ophiopogonis Tuber using HPLC analysis.

Liriopogons (Liriope and Opiopogon) species are used as a main medicinal ingredient in several Asian countries. The Liriopes Radix (tuber, root of Liriope platyphylla) has to be a promising candidate due to their source of phytochemicals. Steroidal saponins and their glycosides, phenolic compounds, secondary metabolites are considered of active constituents in Liriopes Radix. Spicatoside A, a steroidal saponin, could be more efficacious drug candidate in future. In this review, we summarized the available knowledge on phytochemical and pharmacological activities for spicatoside A. It significantly suppressed the level of NF-${\kappa}B$, NO, iNOS, Cox-2, IL-$1{\beta}$, IL-6 and MAPKs in LPS-stimulated inflammation. The production of MUC5AC mucin was increased. MMP-13 expression was down-regulated in IL-$1{\beta}$-treated cells and reduced glycosaminoglycan release from IL-$1{\alpha}$-treated cells. The neurite outgrowth activity, PI3K, Akt, ERK1/2, TrkA and CREB phosphorylation and neurotropic factors such as NGF and BDNF were upregulated with increased latency time. It also showed cell growth inhibitory activity on various carcinoma cells. From this, spicatoside A exerts anti-inflammation, anti-asthma, anti-osteoclastogenesis, neurite outgrowth, memory consolidation and anticancer activities. Further studies are needed on spicatoside A in order to understand mechanisms of action to treat various human diseases.

Nerve growth factor (NGF) is a protein plays a major role in the development and maintenance of central and peripheral nervous system. Recent data suggest that reduced availability of NGF may play a significant role in the pathogenesis of diabetic $polyneuropathy.^{1)}$ In our previous study, steroidal saponin from Liriope platyphylla showed neurotrophic effect by stimulation of NGF synthesis and activation of tyrosine kinase $signaling.^{2)}$ In this study, we examined the neurotrophic effect of Liriope platyphylla (LP); which was from Mylyang(MYL) and Cheongyang(CHE), and Ophiopogon japonicus (CHI) on in vitro and in vivo model for the comparison of their NGF induction. We quantitatively analyzed spicatoside A in the LP and CHI by HPLC. And we investigated the correlation between the contents of spicatoside A and NGF induction efficacy on PC 12 cells and mouse serum. These results suggest that spicatoside A may enhance NGF induction in animal model.

Objectives : Specifications by Processing Methods of Liriope platyphylla (LP) was not established in korea. We carried out method study for manufacture of LP. Above all, LP were purchased and were processed at four kinds. First group had hearts of swelling roots, not cut bodies(LP-A). Second group had not hearts of swelling roots, not cut bodies(LP-B). Third group had hearts of swelling roots, cut bodies(LP-C). Forth group had an aggregate of hearts of swelling roots(LP-D). Methods : We has gained losses on drying, contents of ethanol-soluble extracts, contents of water-soluble extracts and contents of spicatoside A. Results : 1. Losses on drying of all group were less than 18% that is a standard of chinese pharmacopoeia. 2. Contents of ethanol-soluble extracts at LP-C, LP-D were included more than contents of those in the other groups in significance levels. 3. Contents of water-soluble extracts at LP-A, LP-C were included more than contents of those in the other groups in significance levels. 4. Contents of spicatoside A in LP-B were included more than content of spicatoside A in the other groups in significance levels. Resultingly, standards of LP in korea were proposed compatible proposals suggested as below. 1. Losses on drying of LP were less than 15% that is less than that of chinese pharmacopoeia. 2. Form to boil in water must be cutting body with heart of swelling root. 3. Because there is no content of spicatoside A in heart of swelling root, it is not suited to purpose a index component. Conclusions : The subjects of loss on drying and form of LP to boil in water must be contained in korean pharmacopoeia. Moreover, because of much valuable LP in food and medicine, it is urgently required aspect of index component such as spicatoside B, spicatoside C, flavonoid, polysaccharide having medical actions and so on.

The tuber of Liriope platyphylla was extracted with 80% aqueous MeOH and solvent-fractionated with EtOAc, n-BuOH and $H_2O$. Evaluation of growth inhibitory activity of each fractions on various carcinoma cells, A549, SK-OV-3, SK-Mel-2, XF-498 and HCT-15, indicated the n-BuOH fraction to be the highest in the activity. From the fraction, two saponin compounds were isolated through Amberlite XAD-II and silica gel column chromatographies, repeatedly, and their chemical structures were elucidated as spicatoside A and B by interpretation of spectral data, NMR and IR, and adaptation of acid hydrolysis. Spicatoside A showed growth inhibitory activity on carcinoma cells, and the $IC_{50}$ values against A549, SK-OV-3, SK-Mel-2, XF-498 and HCT-15 cells were determined to be 17.3, 21.7, 14.9, 18.8 and $15.6\;{\mu}g/ml$, respectively.

To investigate physiochemical characteristics of Liriope platyphylla tubers by various drying process, proximate constitute, levels of free sugar, organic acid, free amino acid, crude saponin and spicatoside A were analyzed. Drying methods included hot-air drying (DLR, $60^{\circ}C$, 48 hr) and roasting after hot-air drying (RDLR, roasting at $180^{\circ}C$ for 15 min). The moisture, crude protein, crude lipid, ash and NFE (nitrogen free extract) contents of FLR (fresh Liriope platyphylla tuber) were 69.99%, 1.85%, 0.02%, 0.79%, and 27.35%, respectively. The most abundant proximate component of DLR and RDLR was NFE, of which the contents in both sample were 80.09% and 86.07%, respectively. The major free sugars in DLR and RDLR was oligosaccharide II as 56$\sim$57% and the major organic acid was malic acid as 3.06$\sim$3.34%, respectively. In free amino acid, the major amino acid of FLR, DLR and RDLR was serine with contents of 477.41 mg%, 1394.88 mg%, and 180.33 mg%, respectively. The level of serine was significantly decreased by roasting process. The level of crude saponin in FLR, DLR and RDLR were 3.52%, 8.41%, and 10.15%, respectively.

In this study, an ultra-performance liquid chromatography-electrospray ionization-mass spectrometry (UPLC-ESI-MS/MS) method was established for simultaneous determination of the 25 marker components, including chlorogenic acid, gallic acid, oxypaeoniflorin, homogentisic acid, methyl gallate, caffeic acid, 3,4-dihydroxybenzaldehyde, paeoniflorin, albiflorin, liquiritin, nodakenin, ferulic acid, ginsenoside Rg1, liquiritigenin, coumarin, cinnamic acid, benzoylpaeoniflorin, ginsenoside Rb1, cinnamaldehyde, paeonol, glycyrrhizin, 6-gingerol, evodiamine, rutecarpine, and spicatoside A in traditional Korean formula, Onkyung-tang. All analytes were separated on a Waters Acquity UPLC BEH $C_{18}$ analytical column ($2.1{\times}100mm$, $1.7{\mu}m$) at $45^{\circ}C$ using a mobile phase of 0.1% (v/v) formic acid in water and acetonitrile with gradient elution. The MS analysis was carried out using a Waters ACQUITY TQD LC-MS/MS coupled with an electrospray ionization (ESI) source in the positive and negative modes. The flow rate and injection volume were 0.3 mL/min and $2.0{\mu}L$, respectively. The correlation coefficient of all analytes in the test ranges was greater than 0.98. The limits of detection and quantification values of the 25 marker compounds were in the ranges 0.03-19.43 and 0.09-58.29 ng/mL, respectively. As a result, methyl gallate, 3,4-dihydroxybenzaldehyde, evodiamine, and rutecarpine were not detected in this sample and the concentrations of the 21 compounds except for the above 4 compounds were $33.09-3,496.32{\mu}g/g$ in Onkyung-tang decoction. Among these compounds, paeonol was detected at the highest amount as a $3,496.32{\mu}g/g$.
