S-Index Interpretation
The S-Index (Sharing Index) is a comprehensive metric that represents the cumulative impact of all your datasets. It is calculated as the sum of Dataset Index scores across all your claimed datasets.
What it means:
- A higher S-index indicates greater overall impact of your datasets relative to typical datasets in their fields of research
- The S-Index grows as you add more datasets or as existing datasets gain more citations and mentions
- It provides a single number to track your research data impact over time
Current S-Index: 1.3 (sum of 2 datasets Dataset Index scores)

A previously unpublished xanthone named securidacaxanthone D (1) and five known analogues: 1,7-dihydroxyxanthone (2), 7-hydroxy-1,2-dimethoxyxanthone (3), 1,5-dihydroxy-6,7-dimethoxyxanthone (4), 1,7-dihydroxy-3-methoxyxanthone (5), 1,7-dihydroxy-4-methxyxanthone (6) were isolated from the ethyl acetate soluble fraction obtained from the liquid-liquid partition of the crude hydro-ethanolic extract of the roots of Securidaca longipedunculata. Their structures were determined by analysis of 1D -(1H and 13C), 2D-(COSY, HSQC and HMBC) NMR data in conjunction with mass spectrometry (TOF-ESI-MS) and by comparison with reported data. Free radical scavenging activity were evaluated using 1,1-diphenyl-2-picrylhydrazyl (DPPH) as a free radical. Crude extract, ethyl acetate and n-butanol fractions as well as isolated compounds showed different degrees of free radical scavenging activity. Among the extract and fractions tested, the hydro-ethanolic extract was the most active with an IC50 value of 32 μg/mL. Among the compounds, compound 2 was the most active with an IC50 value of 282 μg/mL.
