The genus Euphorbia contains over 2000 species which exhibit a considerable diversity of di- and triterpenes in their latex. The North American species Euphorbia polygonifolia is a low growing plant of Atlantic and Great Lake beaches. The composition of its free and esterified triterpene alcohols was determined by HPLC and (1) H-NMR analyses. An unreported triterpene alcohol was found as 2.6% and 10.3% of the free and esterified fractions, respectively. The structure of the new triterpene alcohol was determined using HMBC, and its configurational assignment was secured by acid-catalyzed isomerization to isotirucallol. The new compound, polygonifoliol, was shown to be Δ(12) -isotirucallol.
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 23 October 2015.
All research outputs
#22,083,809
of 24,641,327 outputs
Outputs from Chemistry & Biodiversity
#1,877
of 2,721 outputs
Outputs of similar age
#227,964
of 267,749 outputs
Outputs of similar age from Chemistry & Biodiversity
#5
of 9 outputs
Altmetric has tracked 24,641,327 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 2,721 research outputs from this source. They receive a mean Attention Score of 2.1. 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 267,749 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 9 others from the same source and published within six weeks on either side of this one. This one has scored higher than 4 of them.
