  • The hot-water extract of fruiting bodies in Fomitella fraxinea had potent anti-complementary activities. After fractionation of water-soluble polysaccharides by DEAE-Sephadex A-25 column chromatography, major anti-complementary activity was concentrated into the FF-AP1 among three polysaccharides (FF-NP, FF-AP1, FF-AP2). FF-AP1 was fractionated into $FF-AP1{\alpha}$ and $FF-AP1{\beta}$ obtained from the adsorbed fraction and unadsorbed fraction by affinity chromatography using a ConA-sepharose 4B column, respectively. $FF-AP1{\beta}$, which exihibited the highest anti-complementary activities had an IR absorption peak of $890cm^{-1}$, and a M.W. of about 15,000 (gel filtration). Anti-complementary activity of FF-AP1 decreased greatly by pronase treatment and periodate oxidation. $FF-AP1{\beta}$ responsible for potent anti-complemenary activities of Fomitella fraxinea was an acidic protein-containing heteroglycan consisted of 48% glucose, 13% mannose, and 12% galactose as major component sugars, 9.6% protein, 6% uronic acids.

  • Objectives: Presently Mume Fructus (MF) undergoes fumigation, which produces benzo[a]pyrene. As a primary analysis with the aims to minimize the production of benzo[a]pyrene and to suggest standards for processing the MF, the steaming method was chosen among the various processing methods, and reviewed through a series of experiments.Methods: Methods:Pitted and un-pitted MF were steamed and processed into samples. After testing level of benzo[a]pyrene, the samples were analyzed for amount of polyphenol and flavonoids. Scavenging activities of the samples for the DPPH and ABTS radicals were tested. In order to measure anti-inflammatory effects of the samples, cell survival rate was investigated using CCK-8 Assay. Also, water extracts of dried and steamed MF were administered to the RAW 264.7 cells to compare expressions of NO, PGE2, IL-1β, and TNF-α. In addition, anti-diarrhea effects of the herbal medicine were tested on animal models with diarrhea induced by MgSO4 and Castor oil.Results: Regardless of pitting, processed MF contained no benzo[a]pyrene. Anti-oxidation effect increased in relation to the frequency of steaming process. However, extracts of dried and steamed MF suppressed different kinds of inflammation factors, and extract of dried MF showed superior anti-diarrhea effect than extract of steamed MF.Conclusions: It is suggested that steaming method of MF is recommended for processing the herbal medicine without the production of benzo[a]pyrene. But regarding that dried and steamed MF showed differences in their anti-oxidative, anti-inflammatory, and anti-diarrhea effects, it is recommended to perform further researches on different efficacies of MF according to their processing methods.
