While searching for useful microorganisms, Saccharomycopsis fibuligera which can be used as cosmetic materials were divided from Jeju island's traditional fermented foods. In this study, blackcurrant extract which contains a large amount of anthocyanin glycosides was fermented with S. fibuligera. HPLC analysis was performed to analyze the components of blackcurrant extract (BE) and fermented blackcurrant fruit extract (FBE). As a result, bio-conversion of delphinidin and cyanidin were able to be identified. In order to verify the anti-oxidant effect of BE and FBE, we investigated radical scavenging ability with DPPH and ABTS. In addition, to confirm anti-inflammatory effect, we investigated inhibition effect of nitric oxide (NO) production on lipopolysaccharide (LPS) - stimulated RAW264.7 macrophages, and inhibition effect of the expression of inflammatory-related proteins (iNOS, COX-2) by western blot analysis. As a result, as FBE has anti-oxidant and anti-inflammatory effects, we suggest that it might be used as an active ingredient for cosmetics.

Plectranthus amboinicus Benth (Lamiaceae) is a medicinal plant native to India, and its leaves are widely used in several traditional medicinal preparations. The purpose of this study was to detect and quantify phenolics present in ethyl acetate and acetone extracts of P. amboinicus leaves, and evaluate their antioxidant, antibacterial, antimutagenic and anticancer activities. The HPLC chromatograms of crude leaf extracts indicated the presence of phenolics like caffeic acid, coumaric acid, rutin, quercetin and gallic acid, which were present in the range of 0.01 - 1.41 mg/g in ethyl acetate and 0.03 - 1.93 mg/g in the acetone extract. The acetone extract showed statistically (p < 0.05) higher antioxidant activity ($IC_{50}$, 99.59 ${\mu}g/ml$) than ethyl acetate extract ($IC_{50}$, 149.96 ${\mu}g/ml$). Statistically (p < 0.05) higher antimutagenicity was shown by acetone extract (46.16%) as compare to ethyl acetate extract (12.16%) at 500 ${\mu}g/plate$ concentration. The acetone extract showed higher antibacterial activity than ethyl acetate extract, and both the extracts showed highest activity against B. cereus (375 and 625 ${\mu}g/ml$, respectively) and lowest activity against Y. enterocolitica (1000 and 1125 ${\mu}g/ml$, respectively). Both the extracts also showed inhibitory effect on cancer cell lines HCT-15 and MCF-7. These results suggest that the leaves of P. amboinicus possess various biological activities, and validate the traditional use of the leaves of P. amboinicus against cold, infection and ulceration.

Cancer is an abnormal growth of cells in body which leads to death. These cells are born due to imbalance in cell proliferation mechanism. In 2018, WHO released new statistics on cancer incidence, mortality, and prevalence worldwide i.e., GLOBOCAN 2018 estimates for 28 types of cancer in which more prevalence of cervix and breast cancer. According to survey, in India about 7.8 million cancer deaths and 11.5 million new cases arise in 2018, which will increase to 19.3 million new cases per year by 2025. Though breast cancer as such is not explained anywhere in Ayurvedic compendia, correlations can be done with the Stana Arbuda. Ayurveda, the ancient system of medicine came into existence 1000's of years ago with an objective of maintaining the health of people and treating diseases. Many herbs used in Ayurveda have been screened for activity against cancer and in-vitro and in-vivo studies have given promising leads. The plant, called as "Mother of Medicine", Haritaki has been extensively studied for its various ailments because of its extraordinary healing potency. Haritaki (Terminalia chebula Retz.), Family: Combretaceae have a great therapeutic value and is widely distributed in India. Dried fruit of Terminalia chebula contains high quantities phenolic compounds consist of ellagic acid, gallic acid and chebulic acid. The fruit extract of T. chebula is having different biological properties like anticancer, antioxidant, hepatic and renal protective activities etc. In this study, we focus on the use of CO₂ extract of Terminalia chebula, on the breast cancer cell line MDA-MB-231. All tests proved that CO₂ extract of Terminalia chebula containing active chemical component, therefore our experiment showed the positive results for CO₂ extract of Terminalia chebula against breast cancer cell line cancer MDA-MB-231. The MTT assay results were used to evaluate the anti-cancer activity of the extract. The percentage of cell growth and cell viability were calculated from tabulated result values of MTT assay. Cell viability MTT assay also showed significant growth inhibition, at the same time statistical analysis of MTT assay also proved significant results.

As part of a continuing investigation to identify free radical scavengers from the fruit bodies of basidiomycetes, we isolated two p-terphenyl compounds, designated as PAl and PA2l, from cethanolic extract of the fruit body of Pasillus panuoides. The methanolic extract was processed by ethyl acetate extraction and silica gel column chromatography to yield two active fraction. PAl was obtained from one of the fractions through Sephadex LH-20 and silica gel column chromatographies and reverse-phase HPLC. The other fraction was purified by Sephadex LH-20 and reverse-phase column chromatographies to produce PA2. The compounds PA1 and PA2 were identified as leucomentin-4 and leucomentin-2, respectively, on the basis of various spectroscopic analyses. These compounds exhibited strong inhibitory activities against lipid peroxidation in rat liver microsomes with IC_{50}$ values of 0.10 and $0.06{\;}\mu\textrm{g}ml$, respectively.

Polyphenolic compounds widely occurring in the traditional medicine plants have been reported to possess strong antioxidant activity. The antioxidative substances of water soluble extract from leaves, stem bark, root bark and fruit powder of Cudrania tricuspidata were tested in three different in vitro experimental models. In oxidation models using DPPH( , ' diphenyl picrylhydrazyl) method, Fe2+ induced linoleic acid peroxidation, and autooxidation of hepatic microsomal membranes, the antioxidative activities of water soluble extract from stem bark were strong than that from leaves and root bark. Fruits of Cudrania tricuspidata contained the highest amounts of polyphenolic compounds among the parts of this plant. The changes in polyphenolic compound contents of fruit powder caused by heat treatment (20oC, 40oC, and 60oC) were also monitored. After water blanching, contents of phenolic compounds was increased slightly in the following order; 20oC(1454mg), 40oC(1487mg), and 60oC(1511mg). These results supports that water soluble extracts from Cudrania tricuspidata contain antioxidative compounds.

Prunus mandshurica var. glabra Nakai (Rosaceae) is widely distributed in South Korea and bears a fruit with a bitter and astringent taste. An ethyl acetate-soluble extract of Prunus mandshurica was found to exhibit significant cytotoxicity against human leukemia cell lines. Bioassay-directed fractionation of this extract using an MTT(3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide) cell proliferation assay as a monitor led to the isolation of the bioactive compounds. Two compounds, 1 and 2 were subsequently found to mediate cytotoxicity against U937, human monocytic leukemia cells. The 50% growth inhibitory concentrations ($IC_{50}$/) of compounds 1 and 2 on U937 were 40 and 62 $\mu\textrm{g}$/mL, respectively.

The manuscript reports synthesis of exceptionally stable gold nanoparticles (GNPs) using Momordica charantia fruit extract. The synthesis approach was optimized by refining three experimental variables including source of the fruit extract (peel, seed, and seed coat), pH of the solution, and temperature of the reaction medium. As synthesized GNPs showed excellent stability against various thiolated compounds (e.g., thioglycolic acid, thiourea, ${\text\tiny{L}}-cystine$, 1-dodecanethiol, and cysteamine hydrochloride). Moreover, these nanoparticles showed distinctive colorimetric responses against $Cd^{2+}$ and thiophenol (TP) from their potential interferences. The limit of detection (LOD) values for $Cd^{2+}$ and TP were determined as 0.186 and $0.154{\mu}M$, respectively.

The biological activities of water extracts from different fruit parts, such as peel, flesh, and placenta, of oriental melon were investigated. The concentrations of total phenolic in fruit extracts were $816.37\;{\mu}g/ml$, $385.23\;{\mu}g/ml$, and $925.56\;{\mu}g/ml$, respectively. Whereas the total flavonoid content in the peel extracts was $231.21\;{\mu}g/ml$, those in the extract of flesh and placenta were $8.16\;{\mu}g/ml$ and $36.07\;{\mu}g/ml$, respectively. The DPPH free radical scavenging activity of each fruit extract at 10,000 ppm was 34.84% for peel, 10.70% for placenta and 9.26% flesh. The ABTS radical cation decolorizing activity of each fruit extract at 10,000 ppm was in fruit extracts were 72.92% for peel, 48.0% for flesh and 74.31% for placenta. In addition, xanthine oxidase inhibitory activity, ${\alpha}-Glucosidase$ inhibition activity, and tyrosinase inhibition activity of the peel extracts appeared to be higher than those of placenta and flesh. Taken together, these results indicated that the peel part of oriental melon contained higher level of total flavonoid content, and several physiological activities including antioxidation, ${\alpha}-Glucosidase$ inhibition activity, and tyrosinase inhibition activity than did the flesh and placenta parts, and suggested that the peel might have a potential to be applicable as a source for functional foods.
