Background: Cardamom (Elettaria cardamom), also known as "Queen of Spices", has been traditionally used as a culinary ingredient due to its pleasant aroma and taste. In addition to this role, studies on cardamom have demonstrated cancer chemopreventive potential in in vitro and in vivo systems. Nevertheless, the precise poly-pharmacological nature of naturally occurring chemo-preventive compounds in cardamom has still not been fully demystified. Methods:In this study, an effort has been made to identify the proapoptopic, anti-inflammatory, anti-proliferative, anti-invasive and anti-angiogenic targets of Cardamom's bioactive principles (eucalyptol, alpha-pinene, beta-pinene, d-limonene and geraniol) by employing a dual reverse virtual screening protocol. Experimentally proven target information of the bioactive principles was annotated from bioassay databases and compared with the virtually screened set of targets to evaluate the reliability of the computational identification. To study the molecular interaction pattern of the anti-tumor action, molecular docking simulation was performed with Auto Dock Pyrx. Interaction studies of binding pose of eucalyptol with Caspase 3 were conducted to obtain an insight into the interacting amino acids and their inter-molecular bondings. Results:A prioritized list of target proteins associated with multiple forms of cancer and ranked by their Fit Score (Pharm Mapper) and descending 3D score (Reverse Screen 3D) were obtained from the two independent inverse screening platforms. Molecular docking studies exploring the bioactive principle targeted action revealed that H- bonds and electrostatic interactions forms the chief contributing factor in inter-molecular interactions associated with anti-tumor activity. Eucalyptol binds to the Caspase 3 with a specific framework that is well-suited for nucleophilic attacks by polar residues inside the Caspase 3 catalytic site. Conclusion:This study revealed vital information about the poly-pharmacological anti-tumor mode-of-action of essential oils in cardamom. In addition, a probabilistic set of anti-tumor targets for cardamom was generated, which can be further confirmed by in vivo and in vitro experiments.

Amaranth(Amaranthus spp. L.) and quinoa (Chenpodium quinoa Willd.) are old crops from South, Central America and Central Asia and their grains have been identified as very promising food crops because of their exceptional nutritive value. Squalene is an important ingredient in skin cosmetics and computer disc lubricants as well as bioactive materials such as inhibition of fungal and mammalian sterol biosynthesis, antitumor, anticancer, and immunomodulation. Amaranth has a component called squalene (2,6,10,15,19,23-hexamethyl-2,6,10,14,22-tetraco-sahexaene) about 1/300 of the seed and $5\~8\%$ of its seed oil. Oil and squalene content in amaranth seed were different for the species investigated. Squalene content in seed oil also increased by $15.5\%$ due to puffing and from 6.96 to $8.01\%$ by refining and bleaching. Saponin concentrations in quinoa seed ranged 0.01 to $5.6\%$. Saponins are located in the outer layers of quinoa grain. These layers include the perianth, pericarp, a seed coat layer, and a cuticle like structure. Oleanane-type triterpenes saponins are of great interest because of their diverse pharmacological properties, for instance, anti-inflammatory, antibiotic, contraceptive, and cholesterol-lowering effects. It is known that quinoa contains a number of structurally diverse saponins including the aglycones, oleanolic acid, hederagenin, and phytolaccagenic acid, which are new potential in gredient for pharmacological properties. It is likely that these saponin levels will be considerably affected by genetic, agronomic and environmental factors as well as by processing. With the current enhanced public interest in health and nutrition amaranth and quinoa will most likely remain in the immediate future within the realm of exotic health foods until such time as agricultural production meets the quantities and qualify required by industrial food manufacturers.

The relationship between environmental growth conditions of savory(Satureja hortensis) and Zn and vitamin B3 has been previously reported. Based on these results, HPLC and GC-MS were used to investigate the levels of phenolic compounds and perform metabolite analysis, respectively, in plants collected from different areas. Differences were observed in the levels of polyphenols and flavonoids depending on sampled areas and natural conditions. Next, HPLC and metabolite analyses confirmed the presence of bioactive substances. The results also showed that the longer the storage time, the higher was the content of carvacrol and of rosmarinic acid. Finally, the difference in the active ingredients was minimal when plants were cultivated under growth conditions similar to those in the place of origin.

Background: Ginseng is a traditional herbal medicine for human health. Ginseng contains a bioactive ligand named gintonin. The active ingredient of gintonin is lysophosphatidic acid C18:2 (LPA C18:2). We previously developed a method for gintonin-enriched fraction (GEF) preparation to mass-produce gintonin from ginseng. However, previous studies did not show the presence of other bioactive lipids besides LPAs. The aim of this study was to quantify the fatty acids, lysophospholipids (LPLs), and phospholipids (PLs) besides LPAs in GEF. Methods: We prepared GEF from white ginseng. We used gas chromatography-mass spectrometry for fatty acid analysis and liquid chromatography-tandem mass spectrometry for PL analysis, and quantified the fatty acids, LPLs, and PLs in GEF using respective standards. We examined the effect of GEF on insulin secretion in INS-1 cells. Results: GEF contains about 7.5% linoleic (C18:2), 2.8% palmitic (C16:0), and 1.5% oleic acids (C18:1). GEF contains about 0.2% LPA C18:2, 0.06% LPA C16:0, and 0.02% LPA C18:1. GEF contains 0.08% lysophosphatidylcholine, 0.03% lysophosphatidylethanolamine, and 0.13% lysophosphatidylinositols. GEF also contains about 1% phosphatidic acid (PA) 16:0-18:2, 0.5% PA 18:2-18:2, and 0.2% PA 16:0-18:1. GEFmediated insulin secretion was not blocked by LPA receptor antagonist. Conclusion: We determined four characteristics of GEF through lipid analysis and insulin secretion. First, GEF contains a large amount of linoleic acid (C18:2), PA 16:0-18:2, and LPA C18:2 compared with other lipids. Second, the main fatty acid component of LPLs and PLs is linoleic acid (C18:2). Third, GEF stimulates insulin secretion not through LPA receptors. Finally, GEF contains bioactive lipids besides LPAs.

This study will evaluate the effect of fermented Morinda citrifolia L. extracts and its marker compounds to provide baseline data for utilizing Morinda citrifolia L. as functional health products. Morinda citrifolia L. and six marker compounds were processed on RAW 246.7 macrophage to test for XTT Cytotoxicity, measure Nitric Oxide and Cyokine formation, and analyze the expression of immune marker genes. Furthermore, LPS and fermented red ginseng extract, a common functional ingredient, are used as positive controls. Our results showed that fermented Morinda citrifolia L and six bioactive compounds did not have any cytotoxic effect in all treatment concentrations and groups. Among six bioactive compounds, SCP and ASE confirmed the formation of NO. In addition, the ASE treatment group showed increased formation of IL-6 and IL-1β and the expression of iNOS and TNF-α. Also, fermented Morinda citrifolia L extract activated the macrophage by enhancing the production of nitric oxide (NO), interleukin (IL)-6, and IL-1β, and the expression of COX2 compared to Morinda citrifolia L. extracts. The result of the study showed that Fermented Morinda citrifolia L. (Noni) and marker compound enhance the innate immunity activity and suggested that the bioactive compound could be applied as a marker compound. Thus, Fermented Morinda citrifolia L. (Noni) could be used as functional food material to develop immunity-enhancing products, and highly functional marker compounds can be utilized as the effective components.

In this study, we investigated the bioactive substances of the Alcalase hydrolysate obtained from fishery processing by-products in Jeju by measuring bioactivities including radical scavenging acitivty, cytoprotective activity against 2,2-azobis-(2-amidino-propane) dihydrochloride (AAPH), and ACE inhibitory activity. This study is important because of utilization of unused fishery processing by-products in Jeju. The Alcalase hydrolysate was prepared through the hot water extraction and enzymatic hydrolysis, and then further separation of the Alcalase hydrolysate was performed by ultrafiltration using 10 kDa molecular weight cut-off membrane. The Alcalase hydrolysate showed the relatively higher DPPH and peroxyl radical scavenging activity ($IC_{50}$ value; 1.30 mg/ml and 0.888 mg/ml, respectively). Also, the Alcalase hydrolysate showed the ACE inhibitory activity with 1.87 mg/ml of $IC_{50}$ value. These biological activities are increased over 1.2 or 2.5 times through the ultrafiltration of the Alcalase hydrolysate. Therefore, the Alcalase hydrolysate obtained from fishery processing by-products in Jeju and the different molecular weight fractions should be given consideration for food and cosmetics ingredient. Furthermore, this research on the utility of fishery processing by-products might be a useful tool into the industry.

To check the possibility of using natural extracts for cosmetic substances, we tested the bioactive effects of 11 crude extracts originating from native plants grown in the Republic of Korea on anti-oxidant and anti-wrinkle activities. When DPPH scavenging activities were measured, the crude extracts of Vitex rotundifolia, Scirpus triangulatus, S. wichurae, S. tabernaemontani, and Aeschynomene indica assays had more than 70% of DPPH scavenging activities at 100 μg/ml concentration. The data from the hydrogen peroxide scavenging assay revealed that the crude extracts from the 10 species, except for Eleocharis mamillata var. cyclocarpa, could scavenge more than 90% at 1,000 μg/ml concentration. The crude extract of V. rotundifolia had the highest xanthine oxidase scavenging activity at a 1,000 μg/ml concentration. Based on the four anti-oxidant assays, the crude extracts of V. rotundifolia, S. triangulatus, S. wichurae, S. tabernaemontani, and A. indica were shown to have excellent anti-oxidant capacities overall. In addition to the anti-oxidant capacities, the crude extract from S. wichurae exhibited high collagenase inhibitory activity, therefore, it could be a promising candidate for a cosmetic ingredient with anti-oxidant and anti-wrinkle qualities. The results of this study indicate that many wild plants native to the Korea Peninsula can be used as excellent natural substances for cosmetics based on their bioactive effects.

Physiological characteristics of brown rice and black rice were investigated to provide the fundamental information of physiological property of rice and to show the potential of rice as a functional ingredient. Bioactive compounds were extracted from brown and black rices with aqueous solvents like 80% ethanol. Total phenolics, flavonoids and antioxidative capacity of brown and black rices' extracts were determined. Brown rice showed much higher amount of total phenolics and flavonoid contents as well as antioxidative capacity than those of milled rice indicating that most of bioactive compounds are located in the bran layer. Black rice showed higher total phenolics and flavonoid contents and antioxidative capacity than those of brown rices. The highest antioxidative capacity was obtained from Heugjinju followed by Heugseol, Sinnongheug-chal, Hopum and Samkwang. This result indicated that antioxidative capacity is affected by total phenolics and flavonoid contents. Both brown and black rices contained higher amount of ferulic acid than that of p-coumaric acid.
