Background:The genera Paris,Trillium,aspidistra,and Polygonatum originally belonged to the family Liliaceae;however,recently,in the APG system,the genera Polygonatum and aspidistra were placed in the family Asparagaceae and the genera Paris and Trillium were placed in the family ***:To study the application of polysaccharide chemotaxonomy in Asparagaceae and Melanthiaceae,we extracted polysaccharides from the rhizomes of plants,including Paris polyphylla ***,Paris daliensis,Paris polyphylla ***,Trillium tschonoskii,aspidistra elatior,aspidistra sichuanensis,aspidistra caespitosa,Polygonatum sibiricum,Polygonatum cyrtonema,and Polygonatum *** and structural characterization of these polysaccharides was performed using molecular weight,monosaccharide composition,Fourier-transform infrared spectroscopy,nuclear magnetic resonance spectroscopy,and scanning electron *** immunomodulatory activities were evaluated using the macrophage cell line,***:In this study,we found that the polysaccharides from the genus Polygonatum and aspidistra were mainly comprised of fructose and glucose;the molecular weights were mostly concentrated between 4.6-6.2 *** polysaccharides from species of genus Polygonatum differed in that they contained acetyl groups,while polysaccharides from species of genus aspidistra did *** and Trillium species polysaccharides mainly consisted of glucose and mannose;the molecular weights of the two major peaks were 6.3-13 kDa and 1-1.5 kDa,respectively;the main differences between polysaccharides were the ratio of glucose and mannose and the degree of *** results suggest that fructans might be the main feature of the family Asparagaceae and fructans with acetyl groups might be the main feature of the genus Polygonatum which is consistent with the results of previous ***,all polysaccharides from the 10 plants promoted phagocytic activity.S

Chemical constituents and antibacterial activities of aspidistra typica

Chinese Journal of Natural Medicines 2018年第6期16卷 465-470页

In the present investigation, we carried a phytochemical study of an ethanol-soluble extract from the root barks of aspidistra typica Baill., a traditional food and herb medicine, leading to the isolation of four different kinds of compounds, including one benzene substituted coumarin, two organic phosphonic compounds, and one xanthone. The novel benzene substituted coumarin typicacoumarin A(1) was a new type of coumarin, and the two new organic phosphonic compounds, typicalphosphine A(2) and typicalphosphine B(3) were isolated for the first time, and their structures were elucidated by spectral techniques, viz.1 D, 2 D NMR spectra and HR-ESI-MS. The xanthone compound typicaxanthone A(4) was discovered from nature for the first time. The two new organic phosphonic chlorides(2, 3) showed stronger antibacterial activities, which were comparable to berberine hydrochloride. And typicaxanthone A(4) showed much stronger antibacterial activity against Escherichia coli ATCC-25922 bacterial strain, while typicacoumarin A(1) showed moderate antibacterial activities, weaker than berberine hydrochloride.
