Studies
• Lipoxygenase
Inhibitory Activuty: Screening of 20 extracts
from different parts of 10 Malaysian plants belong to 4 families showed
the methanol extract of leaves and stems of Stenolobium stans had moderate
inhibitory activity against soybean 15-lipoxygenase.
• Phytochemicals
/ Secondary Metabolites: Air-dried flowers of
Stenolobium stans yielded a new fatty acid cinnamate ester and a mixture
of stigmaterol and sitosterol in a 1:1 ratio.
