For the purpose of developing new immunomodulatory agents from broccoli, ethanol extract (BCEE), hot water extract (BCHW), and crude polysaccharide (BCCP) were isolated from broccoli, and their immunomodulatory activities and chemical properties were examined. In the in vitro cytotoxicity analysis, BCHW and BCCP did not affect the growth of tumor cells and normal cells. Murine peritoneal macrophages stimulated with BCCP showed higher production of IL-6, IL-12, and TNF- α cytokines than those stimulated with BCHW. Also, BCHW and BCCP did not show proliferation of splenic lymphocytes. In the in vitro assay for intestinal immunomodulatory activities, only BCCP enhanced GM-CSF secretion and the bone marrow cell-proliferating activity via cells in Peyer’s patches at 1,000 μg/mL. Also, BCHW mainly contained 33.7% neutral sugars, such as arabinose, glucose, and galactose, and 30.7% uronic acid, and BCCP consisted of 42.6% neutral sugars, including arabinose, galactose, and glucose, and 50.5% uronic acid. The above results lead us to conclude that crude polysaccharide (BCCP) isolated from broccoli causes considerably high cytokine production in peritoneal macrophages and bone marrow cell proliferation, and the polysaccharide extraction process is indispensable for separation of new immunomodulatory agents from broccoli.

The objective of this study was to develop a microcapsule by the entrapment of Ainsliaeaacerifolia extract (AAE) in native starch and citrate starch matrices through spray-drying and dry heating reaction. AAE microcapsules were assessed based on recovery, encapsulation capacity, FT-IR, FE-SEM, swelling power, solubility, releasing pattern of AAE from microcapsules, and antioxidant activity. Upon increasing the addition levels of AAE and adding citric acid in the pre-emulsion mixtures, the spray-drying recovery and encapsulation capacity of AAE microcapsules increased. AAE microcapsules exhibited irregular shapes due to excessive shrinkage of their spheres. FT-IR spectra implied the formation of ester groups between starch molecules and either citric acid or phenolic compounds in AAE. Swelling powers and solubility of AAE microcapsules were significantly higher for citrate starch matrix (relative to native starch). The effects of temperature and enzyme hydrolysis on AAE releasing patterns were similar over AAE microcapsules prepared in this study. AAE microcapsules facilitated the free radical scavenging in an aqueous (relative to alcoholic) reaction system. Overall, the entrapment of AAE into the matrices from native starch and citrate starch would be one of the possible ways to expand the utilization of raw materials, by-product, and extract from Ainsliaeaacerifolia in food industries.

Background : F. fomentarius extracts have been recently reported to process immune-stimulatory and anti-inflammatory effects. In this study, we evaluated the anti-mutagenic effect of F. fomentarius ethanol extracts and the effective chemical components from the extract were analyzed by LC-Q-TOF. Methods and Results : F. fomentarius was extracted with 70% ethanol yielding a crude extract 6.8%. The crude extract was fractionated sequentially to diethyl ether, chloroform, dichloromethane, butanol and water with a yield of 43.9%, 2.958%, 6.8%, 21.6% and 25.5.%, respectively. The anti-mutagenic effect of F. fomentarius extract and its fractions was tested in Ames test by two type of Salmonella typhimurium (TA98 and TA100). Among the five fractions, diethyl ether has shown the highest and significant anti-mutagenic effect (98.3%, at 3,000 ㎍/plate concentration). Moreover, we investigated the chemical constituents of the extract using UPLC-Q-TOF. A total of 10 compounds such as flavonoids (velutin, 3, 4′,5-Trihydroxy-3′,7-dimethoxyflavanone) and fatty acids (γ-linoleic acid, stearic acid) and deterpenoid (kirenol) were tentatively identified with an accurate mass within 10 ppm mass error. Also, flavonoids and fatty acids were detected with higher rate than other compounds based on obtained chromatograms. Conclusion : We demonstrated that F. fomentarius extract and fractions have anti-mutagenic activity through Ames test. Furthermore, we will carry out isolation of each components from its fraction and use them to conduct additional anti-mutagenic test.

In the growth of the Rubus coreanus Miquel fruits, the unripened (10 days) and ripened (25 days) fruits after flowering were harvested. The chemical characteristics of different maturational stages of the unripened and ripened fruits were investigated. Total amount of phenolic compounds was 4.00-7.56% in the unripened fruits and 3.78-5.57% in the ripened fruits, respectively. Furthermore, total amounts of organic acids such as malic, citric, succinic, and oxalic acids were 16.40 mg/ 100 g in the unripened fruits and 28.82 mg/100 g in the ripened fruits, respectively. In organic acids of the unripened and the ripened fruits, citric acid (8.76-15.47 mg/100 g) was the highest amount among other organic acids. Soluble sugars were significantly increased from 11.07 to 21.54% in the unripened and ripened fruits. Therefore, ripened fruits had the high levels of phenolic compounds, organic acids and soluble sugars. For the biological studies of R. coreanus, methanol extracts of R. coreanus leaves, fruits, and stems were evaluated for their insecticidal activities against Myzus persicae (Hemiptera: Aphididae), Plutella xylostella (Lepioptera: Plutellidae) and Spodoptera litura (Lepioptera: Noctuidae) by leaf dipping method. From these results, the extract of R. coreanus leaves revealed potent insecticidal activity against P. xylostella. However, the methanol extracts of R. coreanus fruits and stems had no any insecticidal activity against M. persicae, P. xylostella and S. litura. The R. coreanus leaves have promising potential as new insecticidal agent against P. xylostella.

To examine the utilization possibility of defective coffee beans, non-defective and defective coffee bean were compared by means of its physiochemical properties and antioxidant capacities measured by DPPH radical scavenging activity, FRAP assay, total phenol contents, functional component (trigonelline, caffeine, chlorogenic acid) contents. After roasting process, pH and soluble solid contents of coffee extracts decreased; L* value decreased while a* and b* values increased. DPPH radical scavenging activities of defective green bean extracts were higher than that of non-defective green bean extracts. Immature green bean extract showed the highest radical scavenging activity. In FRAP assay, green bean extracts ranged from 15.28~21.80 mM TE which was higher than roasted bean extracts which showed 14.81~16.38 mM TE. Total phenol contents of green bean extracts ranged 191.06~256.25 mg% GAE which was higher than that of roasted bean extracts showed 161.91~173.44 mg% GAE. The contents of trigonelline, caffeine, chlorogenic acid in immature green bean extract were the highest, which showed 895.20 mg/L, 825.85 mg/L and 3,836.94 mg/L respectively. Each contents were decreased after roasting process. Results of this study suggest that defective coffee bean can be used as a functional food material.
