During the studies on chemical characterization of crude drug precession, constituents Ginseng Radix Rubra were investigated by comparing with those Radix. Panaxynol (4), ginsenosides Ro, Rb1, Rb2, Rc, Rd, Re, Rf, Rg1, Rg2 (11), Rg3 (10a), and Rh1 (9) identified as common both Ginseng, whereas panaxytriol (1), ginsenoside Rh2 (8), 20 (R)-ginsenoside (9a), (S)-ginsenoside (10), (11a) elucidated characteristic Rubra. It was also found that contained larger quantities (9), (11) than The less...
A water extract of the Oriental crude drug "reishi", fruit bodies GANODERMA LUCIDUM, significantly decreased plasma sugar level in mice. Fractionation by monitoring hypoglycemic activity afforded two glycans, ganoderans and B. These glycans elicited remarkable actions normal alloxan-induced hyperglycemic
In order to make a social environment where analysts and decision makers in active businesses sciences can be provided with data they need, we discuss why should how (re)design an called the market of data, each user or provider externalize share value part so that one buy/sell it reasonable condition, e.g., for price as open source if may give merits people general rather than particular segments who pay. Presenting way go, is Innovators' Marketplace on Data Jackets, show vision systematic...
Data integration, which aims to solve problems and create new services by combining datasets, has attracted considerable attention. The discovery of similar datasets that can be combined is critical. In the literature on dataset discovery, it important select an appropriate method for each information need, such as domain. However, conventional studies have evaluated methods in different ways, domains, test evaluation metrics. This factor prevents selection situation. Furthermore, specific...
The decomposition of ginsenoside Rb2 (Rb2) in the rat large intestine after oral administration was investigated detail. A part decomposed and six products (I-VI) were observed on thin-layer chromatogram. Among them, five (I-V) isolated, identification these compounds done by carbon-13 nuclear magnetic resonance (13C-NMR).On basis 13C-NMR analysis, identified as Rd (I), 3-O-β-D-glucopyranosyl-20-O-[α-L-arabinopyranosyl(1→6)-β-D-glucopyranosyl]-20(S)-proto-panaxadiol (II), F2 (III),...
Aqueous methanol/water extracts of the Oriental crude drug “sanyaku”, Dioscorea japonica and D. batatas rhizophors, notably lowered blood glucose concentration in mice. Activity-guided fractionation extract from afforded six glycans, dioscorans A, B, C, D, E, F, which exhibited remarkable hypoglycemic effects normal alloxan-induced hyperglycemic

Identification of martensite and bainite in the ferrous alloys is difficult because both morphologies contain similar complex microstructures. Recently, it was pointed out that frequencies block boundaries are different from each other. In present study, a simple method for identifying using profile suggested. This applied upper lower bainites lath Fe–0.6mass%C alloy. The can be separated by ratio 52 degrees / <011>α' boundaries. Furthermore identified near twin boundary density.
With the emergence of global platforms for trading and buying/selling data, data have become a profitable commodity. The growth such has necessitated further expansion scope in digital economies. To this end, understanding nature available their relationships between them an important challenge expanding use. Thus, study, we assumed on as population metadata samples. quantitatively investigated structural characteristics platforms, while avoiding risk lost business opportunities privacy...
AbstractPolysaccharide fractions of the leaves a number Aloe species significantly reduced blood sugar level in mice. Activity-directed fractionation polysaccharide fraction from arborescens Mill. var. natalensis (Wood, et Ev.) Bgr. yielded two glycans, arborans A and B, which elicited marked hypoglycemic effects normal alloxan-induced hyperglycemic
Four new malonylated dammarane-type triterpene oligoglycosides, named malonyl-ginsenosides Rb1 (1), Rb2 (2), Rc (3), and Rd (4), were isolated from Ginseng Radix, the root of Panax ginseng, their structures elucidated on basis chemical physicochemical evidence.
Antioxidative components in the leaves of green tea (Thea sinensis L.) were examined by using our evalution method based on air oxidation linoleic acid. l-Epicatechin showed strongest activity, its 50% inhibitory concentration (IC50 : 3.54×10-3%) was nearly equal to that butylated hydroxyanisole (BHA).
Improvements in Web platforms for data exchange and trading are creating more opportunities users to obtain from providers of different domains. However, the current limited unilateral information provision users. In contrast, there insufficient means learn what kinds desire purposes. this paper, we propose discuss description items sharing users’ calls as requests marketplace. We also structural differences providable using variables, well possibilities matching. study, developed an...
New saponins, named lucyosides A (1), B (2), C (3), D (4), E (5), F (6), G (7), H (8), besides known ginsenosides-Re (9) and -Rg1 (10), were isolated from herb of Luffa cylindrica ROEM.. On methanolysis 1, 2, 3, 5, 7 8 yielded methyl 21β-hydroxyhederagenin (11), arjunolic acid (12), machaerinate (13), hederagenin (14), maslinic (15) oleanolic (17), respectively. The structures 1-8 elucidated mainly mass, 13C-nuclear magnetic resonance 1H-nuclear spectroscopy.
Quantitative analysis of ginsenoside Rg1, isolated from red ginseng (Panax C. A. MEYER) and one the main saponins, was experimented in rats for studies absorption, distribution, excretion metabolism saponins. The procedure developed as follows. Ginsenoside Rg1 added to biological samples adsorbed on a Servachrom XAD-2 resin column after deproteinization with methanol. eluted 60% methanol aqueous solution further subjected thin-layer chromatography chloroform-methanol-water (65 : 35 10, lower...
