Extracts of the leaves of Druanta repens LINN. were found to contain two new iridoids, durantoside IV and durantoside V together with several known compounds, oleanolic acid, ursolic acid, (E)-cinnamic acid, β-sitosteryl-3-O-β-D-glucopyranoside, (E)-p-methoxycinnamic acid, KNO3 KCl, kusaginin, glucose, durantoside I, and durantoside II. Their structures was elucidated on the basis of spectral and chemical evidence. The absolute configuration of durantoside was determined by using the benzoate rule.

2 H N.m.r.spectroscopy shows that selectively labelled 8-epi-deoxyloganin is efficiently incorporated into lamiide and ipolamiide in Hebenstreitia dentata, whereas selectively labelled deoxyloganin provides no obserable incorporation.
2 H Nmr光谱显示,在Hebenstreitia dentata中,选择性标记的8- epi- deoxyloganin被有效地掺入了lamiide和ipolamiide中,而选择性标记的deoxyloganin没有提供可观察到的掺入。
