The floral organogenesis and development of Delavaya toxocarpa Franch. (Sapindaceae) were studied trader scanning electron microscope and light microscope to determine its systematic position within Sapindaceae. Flo...
Three new triterpenoid saponins, escins IVg (1), IVh (2) and VIb (3) were isolatedfrom the seeds of Aesculus chinensis along with two known saponins, escin IIIa (4) anddesacylescin I (5). Their structures were elucida...
A new triterpenoid saponin named escin IV e was isolated from the seeds of Aesculus chinensis. Its structure was established as 28-tigloylprotoaescigenin-3 beta-O- [beta-D-glucopyranosyl (1-2)] [beta-D-glucopyranosyl ...
A pair of novel geometrically isomeric triterpenoid saponins named escins IVa and IVb, together with known escins Ia and Ib. were isolated from the seeds of Aesculus chinensis. Their structures were determined on the ...
