Petalostemun purpureum

Eriodictyol-7-O-glucoside (Eriodictyol 7-O-β-D-glucoside), a flavonoid, is an Nrf2 activator. Eriodictyol-7-O-glucoside exhibits significant scavenging effects on both hydroxyl radicals and superoxide anions, with IC₅₀ values of 0.28 mM and 0.30 mM, respectively. Eriodictyol-7-O-glucoside increases the nuclear localization of Nrf2 and induces the expression of the Nrf2/ARE-dependent genes. Eriodictyol-7-O-glucoside provides protection against oxygen and glucose deprivation (OGD)-induced oxidative insult. Eriodictyol-7-O-glucoside demonstrates neuroprotective efficacy in a rat model of focal cerebral ischemia (MCAO). Eriodictyol-7-O-glucoside can be used for the study of stroke.

6''-O-β-D-Apiofuranosylastragalin (compound 1) is a flavonoid glycoside that can be naturally extracted from the methanol extract of fresh leaves of Solidago altissima L. (a plant of the genus Solidago in the Asteraceae family). The related methanol extract exhibits antifeedant activity against Thrips palmi and can be used in the research of natural antifeedants for agricultural pest control.

Solidagonic acid is an acidic bitter principle that can be found in the root and rhizomes of Solidago altissima L. Solidagonic acid binds HSET/KIFC1, restores growth in HSET-overproducing fission yeast cells and reverts mitotic spindles from monopolar to bipolar morphology. Solidagonic acid can be used for the research of breast adenocarcinoma.

Petalostemumol G is a flavonol derivative present in Petalostemum purpureum. Petalostemum G has no antibacterial activity. Petalostemumol G is formed by air oxidation of petalostemumol.

Bauerenol acetate is a Triterpenoids product that can be isolated from the herb of Solidago altissima.
