Luteolin from Elsholtzia rugulosa has shown neuroprotective effects in an Alzheimer's disease cell model. It contains flavonoid glycosides apigenin 4'-O-alpha-D-glucopyranoside and 5,7,3',4'-tetrahydroxy-5'-C-prenylflavone-7-O-beta-D-glucopyranoside, among several others. It is active against methicillin-resistant Staphylococcus aureus. Apigenin and luteolin, compounds found in the plant, may help fight influenza virus (H3N2).
