Herpes simplex virus (HSV) is a common causative agent of genital ulceration and can lead to subsequent neurological disease in some cases. Here, using a genital infection model, we tested the efficacy of vinegar-processed flos of Daphne genkwa (vp-genkwa) to modulate vaginal inflammation caused by HSV-1 infection. Our data revealed that treatment with optimal doses of vp-genkwa after, but not before, HSV-1 infection provided enhanced resistance against HSV-1 infection, as corroborated by reduced mortality and clinical signs. Consistent with these results, treatment with vp-genkwa after HSV-1 infection reduced viral replication in the vaginal tract. Furthermore, somewhat intriguingly, treatment of vp-genkwa after HSV-1 infection increased the frequency and absolute number of CD3-NK1.1+NKp46+ natural killer (NK) cells producing interferon (IFN)-gamma and granyzme B, which indicates that vp-genkwa treatment induces the activation of NK cells. Supportively, secreted IFN-gamma was detected at an increased level in vaginal lavages of mice treated with vp-genkwa after HSV-1 infection. These results indicate that enhanced resistance to HSV-1 infection by treatment with vp-genkwa is associated with NK cell activation. Therefore, our data provide a valuable insight into the use of vp-genkwa to control clinical severity in HSV infection through NK cell activation.

6.Three biflavonoids from ethanol extract of the root of Daphne genkwa.
Acta Pharmaceutica Sinica 2005;40(5):438-442
AIMTo investigate the chemical constituents of the secondary metabolites of the roots of Daphne genkwa.
METHODSThe roots of D. genkwa were extracted with 95% ethanol at 60-70 degrees C for 7 days to obtain the crude extract. The crude extract was purified by silica gel and Sephadex LH-20 column chromatography as well as the HPLC techniques. The structures of the isolates were elucidated by combined spectroscopic methods including 1D and 2D NMR, MS, UV, IR and CD.
RESULTSThree new biflavonoids were isolated from the ethanol extract of the roots of D. genkwa and their structures were identified as daphnodorin H-3-methyl ether (1), daphnodorin H-3"-methyl ether (2) and daphnodorin G-3"-methyl ether (3).
CONCLUSIONCompounds 1, 2 and 3 are three new biflavonoids.

In this paper, the correlation between the chemical constituents of Chinese herbal medicines Daphnes Cortex and the ecological factors and soil factors was studied, which provided a reference for the selection of suitable areas for artificial cultivation of Daphne giraldii and wild tending. The geographic information system(GIS) was applied to obtain the ecological factor information of 23 collection sites of Daphnes Cortex, and the soil factor information was determined by the standard procedure in the soil test standard manual. Combining the information of 93 chemical constituents of Daphnes Cortex in 23 collection sites the correlation between components and ecological factors and soil factors was analyzed by statistical methods. The correlation analysis showed that the longitude, annual average rainfall, annual sunshine intensity, annual average temperature in the ecological factors, soil type, effective copper and pH value were the dominant factors affecting the chemical composition of Daphnes Cortex.
