Three new triterpenoid saponins, named julibroside J16 (2), julibroside J17 (3), and julibroside J21 (4), each of which possesses an oleanane triterpenoid aglycone of acacic acid, two monoterpenoid acids, and nine sugar moieties, together with one known saponin, julibroside II (1), were isolated from the stem bark of Albizia julibrissin by chromatographic methods. Their structures were established by chemical and spectroscopic means. Saponins 1, 2, and 4 showed inhibitory activities against Bel… 
A review of acacic acid-type saponins from Leguminosae-Mimosoideae as potent cytotoxic and apoptosis inducing agents
TLDR
Some AATS can be useful in the search for new potential antitumor agents from Fabaceae, and the sequence 28-O-{Glc-(1→3)-[Araf)-1→2)-Glc-Acacic acid}, often encountered in the genera Acacia, Albizia, Archidendron, and Pithecellobium may represent a chemotaxonomic marker of the Mimosoideae subfamily.
New Cytotoxic Triterpenoid Saponins from the Roots of Albizia gummifera (J.F.Gmel.) C.A.Sm.
TLDR
Flow cytometric analyses showed that saponins 1 – 3 induced apoptosis of human epidermoid cancer cell (A431) in a dose‐dependent manner.
New triterpenoid saponin from the stems of Albizia adianthifolia (Schumach.) W.Wight
TLDR
The pro-apoptotic activity of the new isolated saponin 1 was evaluated, using Annexin V-FITC binding assay, on the A431 human epidermoid cancer cell and showed that adianthifolioside J (1) displayed weak pro-APoptoticActivity.
Structural determination of two new acacic acid-type saponins from the stem barks of Albizia zygia (DC.) J. F. Macbr
TLDR
Two new oleanane-type saponins, named zygiaosides C–D (1–2), are established on the basis of extensive analysis of 1D and 2D NMR experiments and chemical evidence.

TLDR
A triterpenoid saponin was obtained from the stem barks of Albizia julibrissin Durazz and named as Julibroside J26, based on the chemical and spectral methods.
A pair of isomeric saponins with cytotoxicity from Albizzia julibrissin
TLDR

Julibroside J 8 -induced HeLa cell apoptosis through caspase pathway
TLDR
It is suggested that julibroside J8 induces HeLa death through caspase pathway through which DNA fragmentation and nuclear damage are observed and DNA fragmentation was exhibited.
