Pangdahai is a traditional Chinese drug, specifically described in the Chinese Pharmacopoeia as the seeds ofSterculia lychnophoraHance. Here, we separatedS. lychnophorahusk and kernel, analyzed the nutrient contents, and investigated the inhibitory effects ofS. lychnophoraethanol extracts on cariogenic properties ofStreptococcus mutans, important bacteria in dental caries and plaque formation. Ethanol extracts ofS. lychnophorashowed dose-dependent antibacterial activity againstS. mutanswith significant inhibition at concentrations higher than 0.01 mg/mL compared with the control group (p<0.05). Furthermore, biofilm formation was decreased byS. lychnophoraat concentrations > 0.03 mg/mL, while bacterial viability was decreased dose-dependently at high concentrations (0.04, 0.08, 0.16, and 0.32 mg/mL). Preliminary phytochemical analysis of the ethanol extract revealed a strong presence of alkaloid, phenolics, glycosides, and peptides while the presence of steroids, terpenoids, flavonoids, and organic acids was low. TheS. lychnophorahusk had higher moisture and ash content than the kernel, while the protein and fat content of the husk were lower (p<0.05) than those of the kernel. These results indicate thatS. lychnophoramay have antibacterial effects againstS. mutans, which are likely related to the alkaloid, phenolics, glycosides, and peptides, the major components ofS. lychnophora.

This study was to evaluate the effects of supplementation of ethanol extracts of chive (CE) and ginger (GE), and their combination (CG) in diets of broiler chickens on their growth, health performance and economic efficiency. Totally 180 male Egyptian broilers from one-day age were randomly assigned to 6 dietary treatments consisting of 3 replicates of 10 chicks each, of which in the diet of the control group (CT) neither ginger nor chive preparation were introduced, meanwhile the diets of birds in the 5 trial groups (CE1, CE2, GE1, GE2 and CG) were supplemented with 0.5% CE, 1% CE, 0.5% GE, 1% GE and 0.5% CE plus 0.5% GE preparations, respectively. In general, supplementation of CE and GE did not significantly affect feed consumption, mortality, performance efficiency index (PEI), and respiratory syndrome in chickens. However, the herb extract preparations could reduce the incidence of diarrhea in broiler chickens during five to-ten-week age periods. Microscopic examination of small intestinal mucosa showed that the heights of villi and the depths of crypts of chicks in the CE2 treatment as well as the diameters of villi of chicks in the CG treatment were significantly (p < 0.05) higher than in the others. In general, supplementation of 1% CE and the combination of 0.5% CE and 0.5% GE preparations improved the growth performance of broilers, and the combination can be an alternative to antibiotics as growth promoters in feeding chicken.

Samama (Anthocephalus macrophyllus) is one of a pioneer indigenous fast growing species in Indonesia which have been used as traditional medicine for various diseases. The objectives were to determine the yield extract, to analyze their antidiabetic activity by inhibition assay for α-glucosidase enzyme activity and chemical analysis with GCMS. Extraction of leaves, bark and wood samples were done by using ethanol 95%. Fractionation the most active  ethanol extract was conducted by using n-hexane and ethyl acetate. The yield of ethanol extracts in leaves, bark and wood were 13.90%, 12.87%, and 2.18% respectively. Based on antidiabetic activity assay, the bark ethanol extract was the most active extract by the IC50 value of 5.86 μg mL-1. Phytochemical analysis on bark ethanol extracts showed that they contained flavonoid, quinon, triterpenoid, saponin and tannin which were assumed have high contribution in antidiabetic activities. The result of fractionation ethanol extract bark showed that the ethyl acetate fraction was the most active fraction (IC50 6.82 μg mL-1). GCMS analysis indicated the presence of dominant phenolic compounds such as pyrocatechol, antiarol, isopropyl myristate and phenol in which were suspected have antidiabetic activity. These results strongly suggested that ethyl acetate fraction of Samama bark was a potential natural source for antidiabetic agents.

Pseudomonas aeruginosa is a Gram-negative organism that can survive under harsh conditions, and it is also an opportunistic pathogen that can produce cell-associated extracellular virulence factors. Several of these virulence factors have been demonstrated to be regulated by quorum sensing (QS). Plantain Herb has been used as antibacterial agents for many centuries in China. In this study, we analyzed Plantain Herb Extracts (PHE) at the concentration of 16 μg/mL (Group A, MIC), 8 μg/mL (Group B, 1/2 MIC) and 4 μg/mL (Group C, 1/4 MIC) for inhibition of the virulence factors production and biofilm formation in P. aeruginosa PAO1. The virulence factors included pyocyanin, rhamnolipids, protease and alginate. PHE showed significant inhibition of virulence factors as compared to the control group without interfering its growth. Thus, PHE might be a potent QS inhibitor and anti-biofilm agent in the treatment of Pseudomonas aeruginosa infections.

The aim of our study was to investigate the effect of Patrinia scabra Bunge polysaccharide (PSB-P2) on cervical cancer cell (U14)-bearing mice. The tumor weight of mice treated with PSB-P2 (40, 80 mg/kg b.w.) was significantly lower than that of the control group and serum lactate dehydrogenase (LDH) activity was decreased, while serum alkaline phosphatase (AKP) level was only changed slightly. Meanwhile, the number of apoptotic tumor cells was significantly increased in the mice by the treatment of PSB-P2 (40, 80 mg/kg b.w.). At the same time, cell cycle analysis showed the accumulation of tumor cells in the G0/G1 phase and a relative decrease in the S phase. On the other hand, using the reverse transcription-polymerase chain reaction (RT-PCR) assay, PSB-P2 (40, 80 mg/kg b.w.) showed the up-regulation of p53 and Bax, and significant inhibition of Bcl-2 in tumor tissues. It suggests a possible mechanism of the inhibitory effect of PSB-P2 on tumor growth.

The aim of the study was to perform comprehensive phytochemical analysis, UHPLC, ATR-FTIR profiling and evaluation of various biological activities of N. Indica rhizome. The phytochemical analysis indicated presence of alkaloids, saponins, and triterpenes. In the antioxidant assay, the methanolic (IC50 40.3±0.04) and chloroform fractions (IC50 40.05±0.21) showed highest DPPH inhition. Like wise, methanolic fraction showed highest FRAP value (756.2±0.06) followed by chloroform (225.0±0.04) and ethyl acetate fractions (193.0±0.21). In the antimicrobial assays, chloroform (MIC <  0.156 mg/ml) and methanol fractions (MIC 0.625 mg/ml) fractions showed significant inhibition of Klebsiella pneumoniae. Also a significant antibiofilm of biofilm formation was recorded by chloroform (IC50 1.73 mg/ml) and ethyl acetate fractions (IC50 1.76 mg/ml). It was concluded that the N. Indica rhizome posess antioxidant, antimicrobial and antibiofilm potential, that may be attributed to high flavonoid contents.
