Sambucus chinensis L. is a native perennial herb distributed throughout China. In traditional Chinese medicine (TCM), this herb is known as Lu-Ying. Ursolic acid is the major effective constituent of Lu-Ying. A rapid, sensitive, and accurate liquid chromatography-mass spectrometry (LC-MS) method for
Currently, there is renewed interest in plant-based medicines and functional foods for the prevention and cure of obesity and its associated risk of cardiovascular disease and metabolic syndrome. In the search for potential anti-obesity compounds from natural sources, the effects of ursolic acid
HPLC was used to determine the content of ursolic acid of Sambucus adnata from different origins. The content of ursolic acid range between 1.14 to 5.7 microg, r = 0.999 8, the recovery range from 99.8% to 101.3%. The method is quick, sensitive and repeatable for determination of the content of
Ursolic acid, an important bioactive compound, was isolated from ethanol extract of aerial parts of Sambucus australis. In order to develop bioactive ursolic acid derivatives, two semi-synthetic compounds were obtained through modification at C-3. The antibacterial activity of the ursolic acid and
A new triterpene, javablumine A (1) along with six known ones were isolated from the aerial parts of Sambucus javanica Blume. They were identified as 3β,23-dihydroxy-11α,12α-epoxy-urs-20(30)-en-28,13β-olide (1), ursolic acid (2), pomolic acid (3), oleanic acid (4), 2α-hydroxy-oleanolic acid (5),
OBJECTIVE
To study the chemical constituents of Sambucus chinensis Lindl.
METHODS
The constituents were isolated and purified by various chromatographic methods and structurally identified by spectral analysis.
RESULTS
5 compounds were obtained as beta-sitosterol (I), oleanolic acid (II), ursolic
In Europe, both the fruits and flowers of Sambucus nigra L. have been used against cold, as well as laxative, diaphoretic, and diuretic remedies. There are also a number of commercially available food products that contain elderberry juice, puréed or dried elderberries. Recent comprehensive
Elderberries are used in the preparation of pie, jelly, punch, wine, or liqueur, as well as in many herbal remedies and food supplements. Elderberry products may provide diaphoretic, diuretic, antioxidant, and immunostimulant activities that offer protection against cold and flu. Herein, we report
OBJECTIVE
To study the chemical constituents of Sambucus adnata.
METHODS
Compounds were isolated by silica gel chromatography. Their structures were elucidated by means of spectral analysis.
RESULTS
Five compounds were isolated and identified as: 1-(3-hydroxy4-methoxyphenyl)-1',2'-ethanediol (1),
The MeOH extract from the whole plants of Sambucus adnata has shown significant protein-tyrosine phosphatase 1B (PTP1B) inhibitory activity. Chemical study on the extract resulted in the isolation of thirteen compounds, including a novel triterpene (1). The structure of 1 was determined to be
OBJECTIVE
The performed investigations aimed on the identification of the anti-inflammatory principal of extracts of leaves of Sambucus ebulus L. (dwarf elder) in order to rationalize the traditional use of this plant for the treatment of chronically inflammatory diseases.
METHODS
Dwarf elder leaf
