Objective To study the antitumor activity of steroid saponins,such as Rhizoma Paridis saponins,Rhizoma Paridis saponin Ⅰ,and diosgenin,extracted from Paris polyphylla var.yunnanensis against lung adenocarcinoma cells.Methods Taking mouse lung adenocarcinoma LA795 cell line and its T739-bearing mice as models,the antitumor activity of steroid saponins of P.polyphylla var.yunnanensis against lung adenocarcinoma cells was carried out in vitro and in vivo.The inhibitory activity of Rhizoma Paridis saponins,Rhizoma Paridis saponin Ⅰ,and diosgenin on the LA795 cell line was studied by means of MTT assay and their antitumor effects in vivo were carried on inbred strains of mice(T739) affected by LA795 metastatic lung cancer.Results The MTT assay of in vitro cytotoxicity of Rhizoma Paridis saponins,Rhizoma Paridis saponin Ⅰ,and diosgenin showed strong cytotoxicity against the growth of LA795 cells.IC50 Values were 24.33 ?g/mL,1.85,and 149.75 ?mol/L,respectively.The tumor weight in all treated groups was significantly lower than that in the control group and the inhibition of tumor growth were 41.82%,29.44%,and 33.94% in their high-dose groups.The metastasis of tumor cells was inhibited by different degrees in treated groups.Conclusion Steroid saponins of P.polyphylla var.yunnanensis have tumoricidal activity on lung adenocarcinoma cell line,both in vitro and in vivo.

OBJECTIVETo compare steroidal saponins-main active ingredients of Paris polyphylla from different areas in Guizhou province, in order to provided basis for further proving Guizhou province to be the planting base of P. polyphylla.

METHODThe contents of nine steroidal saponins, namely paris-VII, (25R)-5-en-spirost-3beta,17alpha-diol-3-O-alpha-L-rhamnopyranosyl-(1-->2) [alpha-L-rhamnopyranosyl(1-->4)]-beta-D-glycopyanoside (PGRR), paris-H, paris-VI, paris-II , paris-III, gracillin, paris-I and paris-V of P. polyphylla from eight areas of Guizhou province were determined by HPLC-UV.

RESULTFive steroidal saponins-paris-VII, PGRR, paris-H, paris-VI and gracillin were detected in all the drugs, which provided basis for distinguishing P. polyphylla. P. polyphylla from Dushan showed the highest content of steroidal saponins (9.62%), followed by Tongren (6.39%), and the lowest was Zunyi (0.99%).

CONCLUSIONSaponins from different areas of Guizhou province show significant difference in variety and content, therefore Dushan is suitable for planting P. polyphylla.

OBJECTIVETo study the chemical constituents in herbs of Paris verticillata.

METHODThe compounds were isolated by column chromatography with silica gel and purified by Sephadex LH-20 and RP-HPLC. The structures were identified by means of NMR analysis.

RESULTNine compounds were isolated from the EtOAc extract and the n-BuOH extract of P. verticillata. Their structures were identified as beta-sitosterol (1), stigmasterol (2), daucosterol (3), beta-ecdysterone (4), 4-hydroxymethyl-gamma-butyrolactone (5), diosgenin-3-O-alpha-L-arabinofuranosyl (1-->4)-[alpha-L-rhamnopyranosyl (1-->2)]-beta-D-glycopyranoside (6), pennogenin-3-O-alpha-L-arabinofuranosyl(1-->4)-beta-D-glycopyranoside (7), pennogenin-3-O-alpha-L-arabinofuranosyl (1-->4)-[alpha-L-rhamnopy-ranosyl (1-->2)]-beta-D-glycopyranoside (8), and pennogenin-3-O-alpha-L-rhamno-pyranosyl (1-->4)-alpha-L-rhamnopyranosyl (1--4)-[alpha-L-rhamnopyranosyl (1-->2)]-beta-D-glycopyranoside (9).

CONCLUSIONCompounds 1-9 are isolated from P. verticillata for the first time, and compounds 3, 5 are isolated from the genus Paris for the first time. The compounds 6-9 showed certain inhibition activeness of LA-795 cells, especially, the effects of compounds 6, 8 and 9 were more significant.

Steatotic liver diseases (SLD) are the principal worldwide cause of cirrhosis and end-stage liver cancer, affecting nearly a quarter of the global population. SLD includes metabolic dysfunction-associated alcoholic liver disease (MetALD) and metabolic dysfunction-associated steatotic liver disease (MASLD), resulting in asymptomatic liver steatosis, fibrosis, cirrhosis and associated complications. The immune processes include gut dysbiosis, adiposeliver organ crosstalk, hepatocyte death and immune cell-mediated inflammatory processes. Notably, various immune cells such as B cells, plasma cells, dendritic cells, conventional CD4+ and CD8+ T cells, innate-like T cells, platelets, neutrophils and macrophages play vital roles in the development of MetALD and MASLD. Immunological modulations targeting hepatocyte death, inflammatory reactions and gut microbiome include N-acetylcysteine, selonsertib, F-652, prednisone, pentoxifylline, anakinra, JKB-121, HA35, obeticholic acid, probiotics, prebiotics, antibiotics and fecal microbiota transplantation. Understanding the immunological mechanisms underlying SLD is crucial for advancing clinical therapeutic strategies.
