Abstract

To extract, purify, and identify the effective constituents of aqueous extract of Fructus Chebulae Immaturus, and analyze the bactericidal effects of total tannins. Preparative thin layer chromatography and semi-preparative high performance liquid chromatography were used to isolate and purify the total tannin fraction. (1)H- and (13)C- NMR spectroscopy were used to elucidate compound structures. The antibacterial activities of total tannins and ethyl gallate on Klebsiella pneumoniae (KP) and Staphylococcus aureus (SA) were determined through minimum inhibitory concentration and minimum bactericidal concentration assays. Their antibacterial mechanisms of action were explored by transmission electron microscopy and scanning electron microscopy. Five compounds were isolated: ellagic acid, ethyl gallate, arjugenin, β-sitosterol, and tri-n-butyl chebulate. Tri-n-butyl chebulate is a newly-reported compound. Total tannins and ethyl gallate both had favorable bactericidal effects against KP and SA. In vivo and in vitro pharmacodynamic experiment demonstrated that the effective components of Fructus Chebulae Immaturus possessed significant antibacterial effects, and were nontoxic and safe. No results of a health care intervention on human participants.

Attention Score in Context

Attention Score in Context

This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 03 July 2016.
All research outputs
#18,465,704
of 22,880,230 outputs
Outputs from BMC Complementary Medicine and Therapies
#2,518
of 3,637 outputs
Outputs of similar age
#266,608
of 350,781 outputs
Outputs of similar age from BMC Complementary Medicine and Therapies
#64
of 98 outputs
Altmetric has tracked 22,880,230 research outputs across all sources so far. This one is in the 11th percentile – i.e., 11% of other outputs scored the same or lower than it.
So far Altmetric has tracked 3,637 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 8.5. This one is in the 17th percentile – i.e., 17% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 350,781 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 13th percentile – i.e., 13% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 98 others from the same source and published within six weeks on either side of this one. This one is in the 22nd percentile – i.e., 22% of its contemporaries scored the same or lower than it.
