| Abstract |
Astragalosides are among the most predominant of the bioactive compounds in the root of Astragalus membranaceus and are differentially concentrated depending on the anatomical part of the root in question. The aim of this study was to analyse astragaloside contents in the periderm, cortex, and xylem of A. membranaceus root, and to compare the contents between peeled and unpeeled roots. Total astragalosides in the periderm were about 8-fold more concentrated than in the cortex, and 28-fold more concentrated than in the xylem. The dry weight percentages of total astragalosides in primary roots were 43.5% in the periderm, 47.2% in the cortex, and 9.30% in the xylem. Furthermore, unpeeled main (primary) roots were enriched in astragalosides by 1.46-fold compared with peeled main roots, whereas unpeeled lateral roots were enriched by 2.33-fold compared with peeled lateral roots. In conclusion, the periderm is the most astragaloside-rich part of the root of A. membranaceus. Therefore, it is necessary to preserve the periderm in order to supply astragaloside-rich roots for use as health food supplements. |

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 29 March 2014.
All research outputs
#20,226,756
of 22,751,628 outputs
Outputs from Journal of Natural Medicines
#395
of 530 outputs
Outputs of similar age
#249,807
of 283,081 outputs
Outputs of similar age from Journal of Natural Medicines
#8
of 11 outputs
Altmetric has tracked 22,751,628 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 530 research outputs from this source. They receive a mean Attention Score of 2.9. This one is in the 1st percentile – i.e., 1% 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 283,081 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 11 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
