A new triterpenoid saponin, together with a known saponin. was isolated from the flowers of lonicera japonica Thunb. Using chemical and spectroscopic methods, mainly 2D NMR technique, their structures were deduced to be 3-beta-D-glucopyranosyl-(1 --> 4)-beta-D-glucopyranosyl-(1 --> 3)-alpha-L-rhamnospyranosyl-(1 --> 2)-alpha-L-arabinopyranosyl hederagenin 28-O-beta-D-glucopyranosyl-(l --> 6)-beta-D-glucopyranoside and 3-alpha-L-rhamnospyranosyl-(1 --> 2)-alpha-L-arabinopyranosyl hederagenin 28-O-alpha-L-rhamnospyranosyl- (1 --> 2)-[beta-D-xylcopyranosyl-( 1 --> 6)]-beta-D-glucopyranoside, respectively.

BACKGROUND： It has been shown that interleukin-1β（IL-1β） can induce fever by activating vascular endothelial cells and macrophages of the supraoptic crest to generate prostaglandin E2, which binds with receptors of the thermo-sensitive hypothalamic neurons. lonicera japonica is one of the medicinal plants used widely in Asia for its antipyretic properties. However, these mechanisms have not yet been intensively studied. OBJECTIVE： To investigate the antipyretic effect and mechanisms of lonicera japonica on IL-1β- induced febrile New Zealand rabbits by observing expression changes of E-type prostaglandin receptor-3 （EP3） mRNA in the preoptic anterior hypothalamus （POAH）. DESIGN： A randomized controlled study. SETTING： Electrophysiological Laboratory at the Department of Pathophysiology, Medical College of Jinan University; Department of Orthopaedics, First Hospital Affiliated to Medical College of Jinan University. MATERIALS： The experiment was performed from April to December 2005, using a total of 32 New Zealand white rabbits of both sexes, weighing 1.5 2.0 kg. All the animal experiments were performed according to the internationally accepted ethical guidelines. lonicera japonica injection was purchased from Huanghe pharmaceutical factory of Xi＇an, China. IL-1βwas purchased from Sigma, USA. METHODS： A total of 32 rabbits were divided randomly into four groups： ① Normal saline （NS） control group;② lonicerajaponica treatment group; ③ IL-1βtreatment group; and ④lonicerajaponica plus IL-1βtreatment group. In the first 3 groups, the rabbits were given separate intravenous （i.v.） injections of l mL NS, l mL lonicera japonica, and 100 ng IL-l β （dissolved in 0.9% NS without pyrogen）. In the lonicerajaponica plus IL-1βgroup each rabbit was given i.v. injections of l mL NS and, 30 minutes later, 100 ng IL-1 β. MAIN OUTCOME MEASURES： Colonic temperature of each rabbit was measured at 0, 10, 20, 30, 40, 50, 60, and 70 minutes after injection and the maximum temperat

The anti-bacterial activities of three types of di-O-caffeoylquinic acids(diCQAs) in lonicera japonica flowers, a traditional Chinese medicine(TCM), on Bacillus shigae growth were investigated and compared by microcalorimetry. The three types of diCQAs were 3, 4-di-O-caffeoylquinic acid(3, 4-diCQA), 3, 5-di-O-caffeoylquinic acid(3, 5-diCQA), and 4, 5-di-O-caffeoylquinic acid(4, 5-diCQA). Some qualitative and quantitative information of the effects of the three diCQAs on metabolic power–time curves, growth rate constant k, maximum heat-output power Pm, and the generation time tG, total heat output Qt, and growth inhibitory ratio I of B. shigae were calculated. In accordance with a thermo-kinetic model, the corresponding quantitative relationships of k, Pm, Qt, I and c were established. Also, the half-inhibitory concentrations of the drugs(IC50) were obtained by quantitative analysis. Based on the quantity–activity relationships and the IC50 values, the sequence of inhibitory activity was 3, 5-diCQA > 4, 5-diCQA > 3, 4-diCQA. The results illustrate the possibility that the caffeoyl ester group at C-5 is the principal group that has a higher affinity for the bacterial cell, and that the intramolecular distance of the two caffeoyl ester groups also has an important influence on the anti-bacterial activities of the diCQAs.

The leaf epidermis of Japanese honeysuckle （lonicera japonica Thunb.） and Wild Honeysuckle （lonicera confusa） in the genus of Flos lonicerae were mainly observed by scanning electron microscopes （SEM） to study the characteristics of stomata, trichomes and dermal cell, etc.. The results showed that stoma exists only on the lower epidermis and its distribution is irregular, and leaf epidermis consist of epidermis cells, stoma complexes and bushy trichomes including glandular hair and non-glandular hair. On the upper epidermis, anticlinal wall caves in sinuous groove to countercheck the transpiration. Evidences from leaf morphological structures serve as another proof on drought-resistant mechanisms. Some strumaes distributing regularly are hypothesized as oxalic calcium on the lower epidermis under laser scanning confocal microscopy （LSCM） with Fluo-3/AM, which can increase their endurance to drought stress. Therefore, the above characteristics of Flos lonicerae can reduce the loss of water and make Japanese honeysuckle and Wild Honeysuckle adapt to the droughty environment at Karst area in southwest China. However, there is some difference of the two species. From the SEM （Scanning Electron Microscopy） result, it is shown that on the upper epidermis, some glandular hair regularly present along the midrib of Japanese honeysuckle, but Wild Honeysuckle has no glandular hair on the upper epidermis, which can verify the relationships of Flos lonicerae species and provide the significance for classification of Flos lonicerae.
