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.

The influences of the extracts from Cinnamomi Cortex, Eucommiae Cortex, Puerariae Radix, Lycii Fructus, Zizyphi Fructus, Schisandrae Fructus, Mume Fructus, Chaenomelis Fructus on mycelial growth and aflatoxin $B_1$ production from Aspergillus parasiticus were analyzed. The pH of the culture media were reduced to below pH 4 by all the herbal extracts after 3 days incubation. However, the pH of the culture media increased above pH 6 after 6 days incubation using the extracts from Cinnamomi Cortex, Eucommiae Cortex, Puerariae Radix and Lycii Fructus. The mycelial growth of A. parasiticus was increased over the amount of the control. Puerariae Radix produced the largest amount of mycelial growth and Chaenomelis Fructus produced the smallest amount of mycelial growth. The productions of aflatoxin $B_1$ from A. parasticus culture were increased by the extracts of Puerariae Radix and Zizyphi Fructus, while inhibited by the extracts of Cinnamomi Cortex, Eucommiae Cortex, Lycii Fructus, Schisandrae Fructus, Mume Fructus and Chaenomelis Fructus. In particular, the extracts of Cinnamomi Cortex, Lycii Fructus and Schisandrae Fructus almost inhibited the production of aflatoxin $B_1$. The production of the total protein from Cinnamomi Cortex, which produced much less aflatoxin $B_1$, and Puerariae Radix, which produced a great deal of aflatoxin $B_1$ from A parasticus were slightly higher than the production of the total protein of the control medium.

Mume fructus is the roasted fruits of Prunus mume and has been used as traditional chinese medicine. In this study, mume fructus extracts were prepared by three different methods including hot water extract (sample1), fermentation extract using Lactobacillus (Sample2-LP and sample-LA) and ethanol extract (sample3). Total polyphenol and flavonoid contents were improved by fermentation process, compared to water extract. Sample 3 showed the highest activity in DPPH radical scavenging. The cytotoxicity of the sample 2-LP was in the range of 83.3% cell viability at $300{\mu}g/m{\ell}$ concentration. Mume fructus extracts in a concentration-dependent manner inhibited melanogenesis and NO synthesis was inhibited. Specifically, the extracts fermented by L. plantarum (sample2-LP) showed higher anti-oxidant activity, anti-inflammatory and skin whitening activity than other extracts. It suggests that sample 2-LP could be potentially used as a resource of materials for functional cosmetics.

The antimicrobial properties of extracts of Prunus mume were tested on Salmonella paratyphimurium and S. typhimurium. First, the Prumus mume was extracted with methanol at several temperatures, and then fractionation of the methanol extracts from Prunus mume was carried out by using petroleum ether, chloroform, ethyl acetate or butanol. Secondly, absorption column chromatoraphy (using a Diaion HP 20) was conducted to eliminate some water soluble materials that might inhibit the antimicrobial activity of some extracts. The antimicrobial activitry of each of the Prunus mume extracts was determined using a paper disc method against several food-borne pathogens, The growth inhibition curve was determine using butanol extracts of Prunus mume against Salmonella typhimurium. The extraction temperature did not have any significant effect on the yield of the extract or on the level of antimicrobial activity. The butanol extract of Prunus mume showed strong antimicrobial activity against Salmonella paratyphimurium and S. typhimurium; a 1,000 ppm of butanol extract of Prunus mume retared the growth of S. typhimurium up to 36 hours.

Mume Fructus extract is used in folk medicine in Eastern Asian countries including Korea. However, its therapeutic effect on thrombosis is not known. Mume Fructus methanol extract (ME) dose-dependently inhibited ADP-induced platelet aggregation and also exhibited about 130% fibrinolytic activity compared to the natto. Oral administration of ME to mice significantly extended tail-bleeding time. ME prolonged both aPTT and PT in human citrated plasma also. These results suggest that the methanol extract from Mume Fructus have antithrombosis activity.

The dried Prunus mume, an alkaline food abundant in organic acids (citric acid, malic acid and tartaric acid), has been largely used in both folklore remedies and Chinese herbal medicine for a long time. This study was performed to investigate the antimicrobial activity of the dried Prunus mume. The fractionation of the methanol extracts from Prunus mume was conducted using petroleum ether, chloroform, ethyl acetate and butanol, respectively. The antimicrobial activity of the Prunus mume extracts was then determined against food-borne pathogens using a paper disc method. The ethyl acetate extract showed the strongest antimicrobial activity against the eigth food-born pathogens used in this present study. Diaion HP 20 column chromatography was performed to remove some sugars that might inhibit the antimicrobial activity of Prunus mume. The strongest antimicrobial activity of ethyl acetate fraction of Prunus mume was shown against Staphylococus aureus. The growth inhibition curve was determined using ethyl acetate extracts of Prunus mume against Staphylococus aureus, which showed the growth inhibition up to 72 hours at 1,000 ppm concentration.
