Nao-Mai-Tong (NMT), a Chinese herbal formula, is used for treating ischemia cerebral apoplexy. To discover the components of NMT with potential in vivo bioactivity and investigate the differences between NMT and its single herb components, this study rigorously compared plasma samples collected from rats dosed with NMT and single-herb extracts at different times through LC-high resolution-MS/MS and data processing (Metworks). The plasma of the NMT group contained a total of 66 identified compounds (25 prototypes and 41 metabolites), including anthraquinones, triterpenoid saponins, isoflavones and phthalides...

REVIEW
Feng Sun, Depo Yang
Progresses in the studies on chemical constituents of Clematis L. (belonging to the family Ranunculaceae) were systematiically reviewed in this article. The plants in this genus have a wide spectrum of constituents as follows: triterpenes, flavonoids, lignans, coumarins, alkaloids, volatile oils, steroids, organic acids, macrocyclic compounds and phenols, etc., among which triterpenoid saponins, flavonoids and lignans are the main components. The triterpenoid saponins are mainly oleanolic type and hederagenin type, most of which are bidesmosidic saponins, substituted with oligosaccharide chains at both C-3 and C-28, and some are substituted with acetyl, caffeoyl, isoferuloyl, p-methoxy cinnamyl and 3,4-dimethoxy cinnamyl groups in the oligosaccharide chains...

Six compounds were isolated from the root of Astragalus chrysopterus Bunge. One of them was identified as a new triterpenoid glycoside, named astrachrysoside A. Its structure was elucidated as 3-O-[alpha-L-rhamnopyranosyl (1----2) beta-D-xylopyranosyl]-cycloastragenol on the basis of physicochemical evidence and chemical reactions. The others were shown to be known compounds, astrasieversianin XV (II), 7,2'-dihydroxy-3',4'-dimethoxy-isoflavane-7-O-beta-D-glucoside (III), soyasaponin I, daucosterol and beta-sitosterol...

Search Tips

Use Boolean operators: AND/OR

diabetic AND foot
diabetes OR diabetic

Exclude a word using the 'minus' sign

Virchow -triad

Use Parentheses

water AND (cup OR glass)

Add an asterisk (*) at end of a word to include word stems

Neuro* will search for Neurology, Neuroscientist, Neurological, and so on

Use quotes to search for an exact phrase

"primary prevention of cancer"
(heart or cardiac or cardio*) AND arrest -"American Heart Association"
