Study On The Pharmacognosy Of The Fruiting Bodies Of Phylloporia Ribis(Lonicera Japonica Thunb.)

Objective To research on the pharmacognosy characteristics of the leaflike layer fungus of Ribesformosanum which is parasitic in Lonicera japonica Thunb plant in order to provide basic information for full use of the fungi resources.Methods To select the plants in the field randomly and study the parasitic situation of the leaflike layer fungus of Ribesformosanum in Lonicera japonica Thunb plant. To combine macro and micro research methods to study the external forms and internal structures; To measure the morphology indexs according to the literature methods, and to have pilot test for chemical compositions using conventional methods; To carry on anti-inflammatory pharmacological research with ear edema model and granuloma model induced with cotton ball in rats and carry on antitumor pharmacological research with S180tumor-burdened mice by filling stomach with superfine powder using furan fluorouracil and west yellow pill as the positive control; To perform toxicological studies according to conventional methods; To culture leaflike layer fungus of Ribesformosanum applying solid and liquid culture method.Results The number, volume and weight of leaflike layer fungus of Ribesformosanum parasitic in honeysuckle plant are related with the age, variety and growth of the plant. The longer the plant grows, the greater the amount of fungus becomes. Fungus has no significant effects on plant growth. It has bigger fruit body, irregular appearance shape and duplicate tegular arrangement. For the section, it is dark brown husk outer, tan bacteria meat inward and pipe hole dense array, a kind of the oval to a kind of circle. For longitudinal cut, the flesh shows tan bacterium; Fungus meat has the same color with bacteria tube, which has darker meat with dark brown color and obvious thinner diameter at the mouth of pipe; Numerous hyphae and a few spores can be seen by powder microscopic observation. Pilot test results show that chemical components contain polysaccharides, peptide, amino acids, protein and alkaloids etc, the same with the components in plant stem, the flower bush. The pharmacological research results show that, with strong anti-inflammatory effects, and good tumors growth suppression in mice S180, it can extend the survival time of adenauer ascites type of mice obviously, while acute toxicity and reproductive toxicity are tiny. Suitable growth temperature for leaflike layer fungus of Ribesformosanum is27℃or so. Its growth will cease above40℃or below5℃.Conclusion This study could not only provide references for the development and utilization of leaflike layer fungus of Ribesformosanum resources, but also laid groundworks for large scale cultivation of this kind of fungus.
