Other claims from this paper (6)
- Observation In TLC, the extract and fractions H and I of S. atropurpurea had an hRf value of 51.2, comparable to the quercitrin standard.
- Observation HPLC retention time of fraction H was 14.819 minutes, consistent with the standard.
- Observation HPLC retention time of fraction I was 14.936 minutes, consistent with the standard.
- Observation The DPPH assay gave an IC50 of 20.37 µL/mL for fraction H, classified as very strong.
- Observation The DPPH assay gave an IC50 of 22.54 µL/mL for fraction I, classified as very strong.
- Observation The authors conclude that quercitrin is present in S. atropurpurea.
