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),
A healthy diet is an important factor in a healthy lifestyle that is becoming increasingly important in today's society. The fruits of European elder (Sambucus nigra L.) are a rich source of bioactive compounds like anthocyanins. In this study, dried and fresh fruits of four cultivated and six wild
Five compounds were separated from Sambucus chinensis and identified as maslinic acid(1), 12alpha, 13-dihydroxyolean-3-oxo-28-oic acid(2), 13-hydroxyolean-3-oxo-28-oic acid (3), 3-oxo oleanolic acid (4), corosolic acid (5). Of them,compound 3 was a new compound, and compounds 1, 2, 4, and 5 were
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
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
