In present study, classification and quality control of Genus Polygonatum were developed using the isolated from Polygonati Odorati Rhizoma and Polygonati Rhizoma. 3 components were isolated from Butanol fractions of Polygonati Rhizoma, and 2 components were isolated from Hexane and Butanol fractions of Polygonati Odorati Rhizoma. All the components were obtained using silica gel and ODS column chromatography. The compounds were identified as adenosine, 14-hydroxylfurost-5-ene-3-O-${\beta}$-D-glucopyranosyl-($1{\rightarrow}2$)-O-${\beta}$-D-glucopyranosyl-($1{\rightarrow}4$)-O-${\beta}$-D-galactopyranosyl-26-O-${\beta}$-D-glucopyranoside, 22-O-methyl-14-hydrocxyfurost-5-ene-3-O-${\beta}$-D-glucopyranosyl-($1{\rightarrow}2$)-O-${\beta}$-D-glucopyranosyl-($1{\rightarrow}4$)-O-${\beta}$-Dgalactopyranosyl-26-O-${\beta}$-D-glucopyranoside, ${\beta}$-Sitosteryl-3-O-${\beta}$-D-D-glucopyranoside, 14-hydoxylfurost-5-ene-3-O-${\beta}$-Dglucopyranosyl-($1{\rightarrow}2$)-O-[${\beta}$-D-xylopyranosyl-($1{\rightarrow}3$)]-O-${\beta}$-D-glucopyranosyl-($1{\rightarrow}4$)-O-${\beta}$-D-galactopyranoside through physicochemical data, spectroscopic methods ($^1H$-NMR, $^{13}C$-NMR, Mass) according references. The quality control of genus Polygonatum were conducted using HPLC quantitative analysis of 14-hydroxylfurost-5-ene-3-O-${\beta}$-D-glucopyranosyl-($1{\rightarrow}2$)-O-${\beta}$-D-glucopyranosyl-($1{\beta}4$)-O-${\beta}$-D-galactopyranosyl-26-O-${\beta}$-D-glucopyranoside, 14-hydoxylfurost-5-ene-3-O-${\beta}$-D-glucopyranosyl-($1{\rightarrow}2$)-O-[${\beta}$-D-xylopyranosyl-($1{\rightarrow}3$)]-O-${\beta}$-D-glucopyranosyl-($1{\rightarrow}4$)-O-${\beta}$-D-galactopyranoside in 30 samples collected throughout Korea and China. This method provided a tool for standardization of mix or misusing the commercial Odorati Rhizoma and Polygonati Rhizoma. As a result, contained quantity of 14-hydroxylfurost-5-ene-3-O-${\beta}$-D-glucopyranosyl-($1{\rightarrow}2$)-O-${\beta}$-D-glucopyranosyl-($1{\rightarrow}4$)-O-${\beta}$-D-galactopyranosyl-26-O-${\beta}$-D-glucopyranoside was measured $0.008{\pm}0.006%$ and 14-hydoxylfurost-5-ene-3-O-${\beta}$-D-glucopyranosyl-($1{\rightarrow}2$)-O-[${\beta}$-D-xylopyranosyl-(13)]-O-${\beta}$-D-glucopyranosyl-($1{\rightarrow}4$)-O-${\beta}$-Dgalactopyranoside was measured $0.026{\pm}0.012%$.

Five compounds were isolated from the roots of Polygala tenuifolia (Polygalaceae). On the basis of spectroscopic evidences, the structures of these compounds were characterized as ${\alpha}-D-(6-O-sinapoyl)-glucopyranosyl(1{\rightarrow}2')-{\beta}-D-(3'-O-sinapoyl)-fructofuranoside$ (P3), ${\alpha}$-D-{6-O-(p-methoxybenzoyl)}-glucopyranosyl-$(1{\rightarrow}2')$-${\beta}$-D-{3'-O-(3',4',5'-trimethoxycinnamoyl)}-fructofuranoside(P4), ${\alpha}$-D-{6-O-(p-hydroxybenzoyl)}-glucopyranosyl-$(1{\rightarrow}2')$-${\beta}$-D-{3'-O-(3',4',5'-trimethoxycinnamoyl)}-fructofuranoside(P5), ${\alpha}-D-glucopyranosyl-(1{\rightarrow}2')-{\beta}-D-(1'-O-sinapoyl)-fructofuranoside$(P6), $1,5-anhydro-D-glucitol$(P7) respectively. ${\alpha}$-D-{6-O-(p-Methoxybenzoyl)}-glucopyranosyl-$(1{\rightarrow}2')$-${\beta}$-D-{3'-O-(3',4',5'-trimethoxycinnamoyl)}-fructofuranoside(P4) and ${\alpha}-D-glucopyranosyl-(1{\rightarrow}2')-{\beta}-D-(1'-O-sinapoyl)-fructofuranoside$(P6) were isolated for the first time from the genus of Polygala. 1,5-Anhydro-D-glucitol(P7) was isolated without hydrolysis for the first time from the root of Polygala tenuifolia.

우리나라 고속도로 총 연장 1,899km 가운데 74개 영업소 구간 1.046km가 폐쇄시 요금체계방식에 의해 매일 영업소간 O-D가 산출되고 있다. 그러나 이러한 O-D는 통행의 기·종점인 교통죤간의 O-D가 아니고 영업소간 O-D인 관계로 그 자료의 정확성에도 불구하고 고속도고 교통분석이나 교통수요예측 등에 거의 활용되지 못하고 있는 실정이다. 이런 상황에서 정확한 영업소간 O-D를 이용하여 교통죤간 O-D를 추정할 수 있다면 고속도로 교통운영분석을 효율적으로 수행할 수 있을뿐만 아니라 기존의 4단계 교통수요예측에 의해 추정되는 것보다 정확한 고속도로 O-D를 얻을 수 있고 국도 등을 포함한 전국 지역간 O-D추정도 가능한 것으로 사료된다. 따라서 본 연구에서는 영업소간 O-D를 이용하여 교통죤간 O-D를 추정하는 모형을 구축하고자 수행되었다. 본 모형에 의해 산정된 교통죤간 O-D 배정결과 고속도로 폐쇄식구간 전구간에 걸쳐 실제 교통량과 17.9%의 오차가 발생되는 것으로 분석되어 본 모형을 이용할 경우 기존 방법들보다 더 정확한 고속도로 이용차량에 대한 교통죤간 O-D 산정이 가능하리라 생각된다.

A study was carried out to evaluate flavonol glycosides in leaves of Symplocarpus renifolius (Araceae). From the water fraction of the MeOH extract, three new flavonol glycosides were isolated along with three known compounds, Kaempferol-3-O-$\beta$-glucopyranosyl-($1{\rightarrow}2$)-$\beta$-D-glucopyranosyl-7-O-$\beta$-D-glucopyranoside, quercetin-3-O-$\beta$-D-glucopyranosy-1-($1{\rightarrow}2$)-$\beta$-D-glucopyranoside, and caffeic acid. The structures of the new flavonol glycosides were elucidated by chemical and spectral analyses a quercetin-3-O-$\beta$-D-glucopyranosyl-($1{\rightarrow}2$)-$\beta$-D-glucopyranosyl-7-O-$\beta$-D-glucopyranoside, isorhamnetin-3-O-$\beta$-D-glucopyranosyl-(1 2)-$\beta$-D-glucopyranosyl-7-O-$\beta$-D-glucopyranosdie, and quercetin-3-O$\beta$-D-glucopyranosyl-($1{\rightarrow}2$)-$\beta$-D-glycopyranosyl-7-O-($6^{IIII}$-trans-caffeoyl)-$\beta$-D-glucopyranoside.

The reaction between methyl 2,3-di-O-benzyl-4,6-di-O-mesyl-${\alpha}$-D-glucopyranoside (1b) and potassium superoxide resulted in hydrolysis, and gave methyl 2,3-di-O-benzyl-${\alpha}$-D-glucopyranoside (1) as a sole product. When the reaction was performed with a vicinal dimesylate, methyl 4,6-O-benzylidene-2,3-di-O-mesyl-${\alpha}$-D-altropyranoside (4b), again the hydrolysis product, methyl 4,6-O-benzylidene-${\alpha}$-D-altropyranoside (4) was obtained. However, the reaction of potassium superoxide with another vicinal dimesylate, methyl 4,6-O-benzylidene-2,3-di-O-mesyl-${\alpha}$-D-glucopyranoside (3b), nucleophilic displacement took place to afford methyl 4,6-O-benzylidene-${\alpha}$-D-altropyranoside (4). Apparently different results from two trans vicinal dimesylates, 3b and 4b are explained by the transient formation of epoxides, methyl 2,3-anhydro-4,6-O-benzylidene-${\alpha}$-D-allopyranoside (8) and methyl 2,3-anhydro-4,6-O-benzylidene-${\alpha}$-D-mannopyranoside (9) by $KO_2$. The reaction between the allo epoxide 8 and $KO_2$ gave altro 4. The manno epoxide 9 also afforded altro 4 as the major product. Facile epoxide formation by the reaction of a vicinal dimesylate and superoxide was also observed with 3-O-benzyl-1,2-O-isopropylidene-5,6-di-O-mesyl-${\alpha}$-D-glucofuranose: 5,6-anhydro-3-O-benzyl-1,2-O-isopropylidene-${\beta}$-L-idofuranose was obtained.
