Antioxidative, antidiabetes, antibacterial, anticancer and angiotensin-converting enzyme (ACE) inhibitory activities of methanol extracts of dried persimmon, fresh persimmon and persimmon leaves were investigated. Total polyphenol content of dried persimmon, fresh persimmon and persimmon leaves were 147.79, 301.45 and $315.90\;{\mu}g/mg$, respectively, of which fresh persimmon and persimmon leaves had significantly higher total polyphenol than dried persimmon. Activities of DPPH radical scavenging, lipid peroxidation inhibition and salivary $\alpha$-amylase inhibition were increased in persimmon leaves related to total polyphenol contents. Anticancer activities against AGS of fresh persimmon and persimmon leaves were $65{\sim}70%$; however, there were no significant differences between dried persimmon and fresh persimmon on free radical scavenging activity and inhibitory activity of salivary $\alpha$-amylase. Also, extracts of dried persimmon, fresh persimmon and persimmon leaves showed good ACE inhibitory activities. Dried persimmon and fresh persimmon showed antibacterial activities on E.coli O157:H7. Therefore, there are many difference activities by dried and parts of persimmon. From this result, it is suggested that persimmon leaves is believed to have possible antioxidative, antidiabetes and anticancer capacities by polyphenol, but further studies on the identification of the active compound(s) as antioxidant, antidiabetic, antihypertensive and antibacterial materials will be needed to develop a better understanding of its potency on persimmons.

For the comparison of the urushiol composition and biological acitivity between the fresh sap and fire distilled sap of lacquer tree(Rhus vernicifera), we analysed the urushiol composition by HPLC and EI-MS, and investigated the antioxidative , antimicrobial and anticancer acitivities according to solvent fractionations. There was no difference in the urushiol composition between fresh and fire distilled saps of lacquer tree. The hexane frqctionsof two saps showed a strong DPPH radical scaverging activity (RC50 : 7.0-7.5$\mu\textrm{g}$). They also showed a strong antifungal activity onthe spore germination of Cladosporium herbarum(MIC : 8$\mu\textrm{g}$/ml), whereas they have no or low activity against the bacteria(BAcillus subtilis , Escherichia coli). In addition , hexane and butanol fractions of two saps showed a strong inhibitory activity against cultured tumour cell lines (GI50 : 0.35, 12.29$\mu\textrm{g}$/ml) in vitro. These results confirm that the fresh sap and fire distilled sap might have the similar urushiol compositions and biological activities.

Santalum album Linn. [Family: Santalaceae] is commonly known as white sandalwood, sandal safaid and safed chandan. It is one of the most valuable trees and second costliest wood in the world. Sandalwood and its oil is extensively used in the Unani and other traditional systems of medicine as it has blood purifier, anti-inflammatory, analgesic, exhilarant, cardiotonic, antiseptic, nervine tonic and expectorant properties. It is used in skin, cardiac, liver, gastrointestinal, respiratory, integument and urogenital disorders. These uses are supported and proven by many in vitro or in vivo studies. The proven pharmacological activities of S. album are antimicrobial, anti-oxidant, anti-inflammatory, antimutagenic and anti-fatigue. The research has proven that sandal oil or its constituents have anti-microbial activity. Sandalwood oil showed skin cancer preventive effect in mice and its constituent alpha santalol showed the anticancer property. The methanolic extract of wood was confirmed for antioxidant, free radical scavenging, analgesic and anti-inflammatory activities. ${\alpha}$ and ${\beta}$ santalols present in sandal oil showed sedative effects. Sandalwood tea had a significant effect on heart muscles of frog and showed increased myocardial contractility. Its oil showed significant changes in hepatic xenobiotic metabolizing enzymes. Sandalwood oil and its major constituents showed less acute oral and dermal toxicity in laboratory animals. Hence, the aforementioned studies justify the uses of sandalwood and its oil mentioned in the classical Unani literature. However, further clinical trials are suggested to confirm its efficacy and safety in humans.

We investigated the antioxidant, physicochemical, and sensory characteristics of dried type sodium-reduced Bibimbap using dandelion complex powder (DCP). DCP is known to add moisture to the skin and relieve symptoms of atopic dermatitis. The sodium content of the standard sample was 1,110.87 mg per serving. The sodium was significantly reduced by 30%, resulting in 762.62 mg of sodium for the reduced sodium group (p<0.05). The ash contents of the standard sample group with DCP showed the highest value (3.17%) in all samples and was affected by minerals of DCP (p<0.05). The total flavonoid contents and ABTS radical scavenging activity, indicators of antioxidant, anticancer and antibacterial activities, showed significantly high activities with addition of DCP (p<0.05). In the sensory results, bulgogi and savory flavor of the samples with DCP showed significantly higher values, and samples with DCP received the highest scores for after-taste. All samples were confirmed to be microbiologically safe according to the food code applied to food manufacturers. Pathogenic microorganisms tests were either negative or not detected in all samples.
