Abstract
Daphjamilin, a new dimeric coumarin glycoside, was isolated from the roots of Daphne oleoides and assigned the structure 7‐O‐α‐L‐rhamnosyl‐8‐[2‐oxo‐2__H__‐1‐benzopyran‐7^′^‐(hydroxy)‐6^′^‐yl]‐2__H__‐1‐benzopyran‐2‐one by extensive NMR studies. Copyright © 2001 John Wiley & Sons, Ltd.

The structure of a new chromone glycoside isolated from smilax glabru, named smiglanin [3,5,7trihydroxychromone 3-O-a-~-rhamnopyranoside] (C15H1609), was determined using NMR techniques. The carbon skeleton of the molecule was established mainly by the 2D INADEQUATE method coupled with a computerize
## Abstract The structure of a new bufadienolide glycoside, cinobufagin 3‐__O__‐β‐D‐glucoside, was determined by extensive 1D and 2D NMR techniques (^1^H, ^13^C, DEPT, COSY, HSQC, g‐HMBC and NOESY). The complete assignments of the ^13^C and ^1^H spectral data were also carried out. Copyright © 2002
## The investigation of the chemical constituents of Symplocos racemosa Roxb led to the isolation of two new glycosides, symcomoside A (1) and symcomoside B (2), together with one known glycoside, tortoside C (3), which is reported for the first time from this plant. The structures of the new comp
Two isomers of betamethasone 9a-fluoro-11~,17a,21-trihydroxy-l6~-methy~pregna-l,4diene-3,2~ione (l), were isolated from the mother liquor of a manufacturing process and were characterized by NMR spectroscopy. They were identified as 8a-fluoro-l1~,17a,2l-trihydroxy-l6~-methyl-9~-pregna-l,4-diene-3,20
