Enterolacaciamine (1), a new potential O-GlcNAcase activator, along with three known triterpenoid saponins, concinnoside B (2), concinnoside D (3), and julibroside A3 (4) was isolated from the leaves of Enterolobium cyclocarpum. Their structures were elucidated by chemical and spectroscopic methods (UV, MS, 1D and 2D NMR). Their effects on O-GlcNAcase activity were evaluated using O-GlcNAcase enzymatic assay. The results showed that compound 1 could obviously enhance the activity of O-GlcNAcase…

Cancer Chemopreventive Properties of Sulfated Enterolobium cyclocarpum Extract
Enterolobium cyclocarpum could be used as an alternative gum in health food industries to provide cancer prevention in high-risk populations because of its anti-tumor and anti-inflammatory properties.


Chemical and 13C NMR studies of Enterolobium cyclocarpum gum and its degradation products.
A structural study of the gum exudate from Enterolobium cyclocarpum has been carried out using chemical methods and 13C NMR spectroscopy. The results reveal that the structure of this gum is
New triterpenoid N-acetylglycosides with molluscicidal activity from Tetrapleura tetraptera Taub.
Activity-guided fractionation of the MeOH extract of the fruits of Tetrapleura tetraptera TAUB. (Mimosaceae) afforded 4 saponins 1–4, which exhibited strong molluscicidal properties against the
Antiproliferative hopane and oleanane glycosides from the roots of Glinus lotoides.
Three new hopane saponins, lotoidosides A - C (1 - 3), and four new oleanane sapoides D - G (4 - 7), were isolated from the roots of Glinus lotoides L. (Molluginaceae) by extensive NMR spectroscopy and ESI-MS analysis.
Studies on the constituents of Calliandra anomala (Kunth) Macbr. III. Structure elucidation of six acylated triterpenoidal saponins.
Six new triterpenoidal saponins, called calliandra saponins G(1), H(2), I(3), J(4), K(5) and L(6), were isolated from the branches of Calliandra anomala (Kunth) Macbr. The structures of these

Cytotoxic glycosides from Albizia julibrissin.
During the course of a study of leguminous plants, cytotoxicity was demonstrated by the crude saponin fraction of Albizia julibrissin and the structures of three novel saponins, julibrosides I-III (1-3), inclusive of a cytotoxic principle, were elucidated.
Isolation and structure elucidation of three triterpenoid saponins from Acacia auriculiformis.
Three new triterpenoid saponins isolated from the fruits of Acacia auriculiformis, were identified as acacic acid lactone-3-O-beta-D-glucopyranosyl, acaciside-I, proacaciaside-II and acaciamine based on their spectral properties and some chemical transformations.
Entadosides A–D, triterpene saponins and a glucoside of the sulphur-containing amide from the kernel nuts of Entada phaseoloides (L.) Merrill
