翼首草的红外光谱鉴别 总被引:1,自引:0,他引:1
采用傅里叶变换红外光谱法直接测定藏药翼首草不同产地、不同药用部位的红外光谱,并比较了它们的红外光谱差别。实验结果表明:翼首草药材根与地上部分的红外指纹图谱有明显差别,可用于药用部位的鉴别;产地相距较远药材的红外光谱差别也较大,此方法也可用于鉴别药材产地。翼首草的红外光谱对不同药用部位、不同产地的翼首草有一定的鉴别意义。 相似文献

Aim of the study
This study evaluates the anti-inflammatory and analgesic activities of the ethanol and aqueous extracts of a Tibetan herb Pterocephalus hookeri (C.B. Clarke) Höeck to provide experimental evidence for its traditional use such as cold, flu and rheumatoid arthritis.Materials and methods
Investigations on the analgesic effects of P. hookeri (C.B. Clarke) Höeck were carried out, including hot-plate test and acetic acid-induced writhing. The anti-inflammatory activities were observed by utilizing the following models: carrageenin-induced edema of the hind paw of rats, cotton pellet-induced granuloma formation in rats, acetic acid-induced permeability, and xylene-induced ear edema in mice. The effects of the administration of indomethacin were also studied.Results
It has been shown that the ethanol and aqueous extracts significantly increased the hot-plate pain threshold and reduced acetic acid-induced writhing response in mice. The ethanol and aqueous extracts remarkably inhibited the increase in vascular permeability induced by acetic acid and ear edema induced by xylene. The ethanol extract also significantly decreased the carrageenin-induced rat paw edema perimeter and inhibited the increase of granuloma weight.Conclusion
The results show that the ethanol and aqueous extracts have both central and peripheral analgesic activities and as anti-inflammatory effects, supporting the traditional application of this herb in treating various diseases associated with inflammation and pain. 相似文献18.
