| Abstract |
To discriminate the cortex herbs of Chinese Pharmacopoeia, the second internal transcribed spacer (ITS2) of ribosomal DNA of 51 samples belonging to 19 kinds of cortex herbs were analyzed in this paper. Sequence assembly was performed using the CodonCode Aligner. Phylogenetic study was performed using the molecular evolutionary genetics analysis (MEGA) 4.0 software in accordance with the Kimura 2-Parameter (K2P) model. Phylogenetic tree was constructed using the neighbor-joining (NJ) method. We found that the ITS2 sequences of the studied samples ranged from 207 to 256 bp in length and easy to be amplified. The intraspecific genetic distance of the cortex herbs was between 0 and 0.073, which was lower than their interspecific genetic distance (mean, 0.868; minimum, 0.101). In the cluster dendrogram, all the studied medicinal materials with several samples, were monophyletic. It is concluded that ITS2 barcode is suitable for the identification of cortex herbs of Chinese Pharmacopoeia, and it will play an important role in the field of identification of traditional Chinese medicine (TCM). |

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 18 July 2012.
All research outputs
#18,310,549
of 22,671,366 outputs
Outputs from Journal of Natural Medicines
#301
of 529 outputs
Outputs of similar age
#110,225
of 143,552 outputs
Outputs of similar age from Journal of Natural Medicines
#6
of 16 outputs
Altmetric has tracked 22,671,366 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 529 research outputs from this source. They receive a mean Attention Score of 2.9. This one is in the 25th percentile – i.e., 25% 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 143,552 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 10th percentile – i.e., 10% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 16 others from the same source and published within six weeks on either side of this one. This one is in the 12th percentile – i.e., 12% of its contemporaries scored the same or lower than it.
