  • Biologically active compounds in Polygonatum sibiricum were extracted using organic solvents as hexane, CHC1$_3$, n-butanol corresponding each component. Compound II was purified from hexane layer and the chemical structure of compound II was characterized using IH-nmr, 13C-nmr, DEPT135, COSY, HMQC, HMBC spectrum and MS-spectrum. Consequently, the chemical structure of compound II was determined as 2-Hydroxy-3-(9,12-(9E,12E)-Octadecadienoyloxy) propanoic acid.

  • This work was designed to determine the optimum roasting conditions with application of a pressure roaster for improving the roasting process of the Polygonatum sibiricum tea which has been roasting with a traditional method. Soluble solid content of the Polygonatum cibiricum tea was 63.16% in the tea roasted at 0.85kgf/$\textrm{cm}^2$(roasting pressure) and 13.9min(roasting time) which were maximum point by the ridge analysis. The optimum conditions predicted for each corresponding sensory properties of the Polygonatum cibirium tea were 0.87kgf/$\textrm{cm}^2$ and 9.2min in color, 0.89kgf/$\textrm{cm}^2$ and 9.7min in sweet 0.72kgf/$\textrm{cm}^2$ and 5.4min in burnt flavor, 0.89kgf/$\textrm{cm}^2$ and 9.9min in appetizing flavor, 0.87kgf/$\textrm{cm}^2$ and 9.3min in aftertaste, 0.89kgf/$\textrm{cm}^2$ and 10.0min in aroma, and 0.88kgf/$\textrm{cm}^2$ and 9.6min in overall acceptability of the tea. The optimum conditions based on the soluble solid content and sensory properties of the Polygonatum cibiricum tea, were 0.83~0.88kgf/$\textrm{cm}^2$ and 9.7~10.4min.

  • The phylogenetic relationship of Polygonatum species were examined by RAPD analysis. Polygonatum Rhizoma is called 'Whang-jung', and used Polygonatum sibiricum Redoute in defined as a source plant in Korean Pharmacopoeia. Polygonati Odorati Rhizoma is called 'Wui-yu', and P. odoratum Druce var. pluriflorum Ohiwi and related species are defined is source plants in Korean Herbal Pharmacopoeia. In UPGMA analysis, Polygonum was divided into two major groups. Polygonatum sibiricum and P. stenophyllum was placed in a cluster. On the other hand, P. falcatum A. Gray was included in the other cluster comprising. P. odoratum and related species, which are used as source plants for Polygonati Odorati Rhizome.

  • A bisdesmosidic cholestane glycoside was isolated from the rhizomes of Polygonatum sibiricum and the structure was elucidated by spectroscopic methods and acid hydrolysis as (22S)-cholest-5-ene-$1{\beta}$,$3{\beta}$,$16{\beta}$,22-tetrol 1-O-${\alpha}$-L-rhamnopyranosyl 16-O-${\beta}$-D-glucopyranoside. This compound exhibited weak cytotoxic activity with the $IC_{50}$ value, $63.6\;{\mu}M$ in human MCF-7 breast cancer line, whereas it failed to show agonistic activity at $100{\mu}M$ in TGR5 assay with Chinese hamster ovary (CHO) cells. This is the first report of a bisdesmosidic cholestane glycoside from Polygonatum species and the full assignments of $^1H$, $^{13}C$ NMR by HMBC, TOCSY and NOESY experiments were provided.

  • The organoleptic properties of granule tea was optimized for granulation of Polygonatum sibiricum Delar(Dunggulle) tea for exclusion of scorched smell and increase of consumption. The length of 2 mm was suitable to cutting size of Dunggulle for preparation of the roasted Dunggulle. The optimum sensory conditions for aroma of Dunggulle granule tea showing 7.85 organoleptic score were 80.61% in ratio of Dunggulle extracts to total extracts, 12.77% in content of total extracts and 37.33% in rate of glucose to total sugar. The highest score of overall palatability was 5.96 at 61.11% in rate of Dunggulle extracts to total extracts, 13.79% in content of total extracts, and 60.92% in rate of glucose to total sugar.

  • Water-soluble polysaccharides isolated from the rhizome of Polygonatum sibiricum and fractionated using ionexchange chromatography were investigated to determine their structure and immunostimulating activity. Crude and fractions ($F_1$ and $F_2$) consisted of carbohydrates (85.1~88.3%) with proteins (4.51~11.9%) and uronic acid (1.79~7.47%), and included different levels of mannose (62.3~76.3%), glucose (15.2~20.3%), galactose (4.35~15.3%), and arabinose (4.00~7.65%). The crude contained two peaks with molecular weights (Mw) of $151{\times}10^3$ and $31.8{\times}10^3$, but $F_1$ and $F_2$ exhibited one major peak with Mw of $103{\times}10^3$ and $628{\times}10^3$, respectively. Little immunostimulatory activity was observed by the crude; however, $F_1$ and $F_2$ significantly activated RAW264.7 cells to release nitric oxide and various cytokines, suggesting they were potent immunostimulators. The backbone of the most immunostimulating fraction ($F_1$) was ($1{\rightarrow}4$)-manno- and ($1{\rightarrow}4$)-gluco-pyranosyl residues with galactose and glucose attached to O-6 of manno-pyranoside.

  • Rhizomes of Polygonatum species belong to Liliaceae are important herbal drugs in the traditional medical practice of Asian region. Two representative Chinese drugs derived from this genus are Hwangjeong and Okjuk. Though botanical origins of these drugs are officially listed as P. falcatum, P. sibiricum and P. kingianum for Hwangjeong and P. odoratum var. pluriflorum for Okjuk in the Korean Pharmacopoeia and Korean Herbal Pharmacopoeia, respectively, they are often sold as a mixture of several different species in the market.
