This study aims at observing effect of global R&D cooperation outcome and global business ability of small businesses by national aid program. Also, this study aims to observe between national aid program and global R&D cooperation outcome. As a result, the national aid programs can be used to get global level technique and develop global markets. Also, the programs can positive effects to the small businesses for making global network and ability. They can be good methods for growing as global small businesses in the world.
From the EtOAc fraction of Eugenia caryophyllata, four compounds were isolated through activity-guided silica gel column chromatography, From the result of spectroscopic data including NMR, MS and IR, the chemical structures of the compounds were determined as 1-allyl-4-hydroxy-3-methoxybezene acetate (eugenol acetate, 1), 1-allyl-4-hydroxy-3-methoxybezene (eugenol, 2), 3β-hydroxyolean-12-en-28-oic acid (oleanolic acid, 3) and 2α, 3β-dihydroxyolean-12-en-28-oic acid (maslinic acid, 4). Compounds 3 and 4 were isolated for the first time from this plant. Also, compounds 1, 2 and 3 exhibited relatively high platelet aggregation inhibitory activity with the IC50 values of 0.24, 0.09 and 0.07 mM, respectively. Compound 2 significantly prolonged activated partial thromboplastin time (aPTT) with the value of 124±11.2 seconds as compared to the control with the value of 37.5±2.2 seconds at the concentration of 50 μg/ml. Compounds 1 and 3 revealed inhibitory activity on farnesyl protein transferase (FPTase) with the IC50 values of 0.49 and 0.24 mM and compounds 1 and 2 highly inhibited the growth of rat-H-ras cells with the Gl50 values of 6.63 and 5.70 μm, respectively.
Three stigmastane-type sterols and one ergostane-type sterol were isolated from the ethyl acetate soluble fraction of the aerial parts of Artemisia princeps Pampanini (Sajuarissuk). From the results of physico-chemical data including NMR, MS and IR, the chemical structures of the compounds were determined as stigmasta-5,22-dien-3,β-ol (stigmasterol, 1),stigmast-5-en-3β-ol(β-sitosterol,2), 5β,8β-epidioxy-5β,8β-ergosta-6,22-dien-3β-ol(ergosterol peroxide, 3), and β-sitosterol 3-O-βD-glucopyranoside(daucosterol,4).
The flowers of Chrysanthemum boreale Makino were extracted with 80% aqueous MeOH, and the concentrated extract was partitioned with n-hexane, EtOAc, n-BuOH and H2O. Two compounds from the n-hexane fraction and one glucoside from the n-BuOH fraction were isolated through the repeated silica gel and ODS column chromatographies. From the result of physico-chemical data including NMR, MS and IR, the chemical structures of the compounds were determined as β-sitosterol (1), phytol (2) and zingerone 4-O-β-D-glucopyranoside (3). Compounds 2 and 3 were isolated for the first time from this plant.
