Abstract
Chemical investigation of the methanol extract of the aerial parts of Buddleja asiatica resulted in the isolation of a new iridoid glycoside, buddlejasiaside A (1) and 11 known compounds: 6- O -[α-L-(4-isoferuloyl)-rhamnopyranosylcatalpol (2), specioside (3), verminoside (4), minecoside (5), 6- O -( p -hydroxybenzoyl)-ajugol (6), 6- O -caffeoyl ajugol (7), litanthosalin 8), eurostoside (9), 10- O -caffeoylaucubin (10), phlorizin (11), and garashangin (12). Their chemical structures were identified based on the MS and NMR spectroscopic analyses and comparing with the data reported in the literature. Compounds 1, 2, and 8-10 showed the modest inhibitory effects against nitrite production in LPS-stimulated BV2 microglia, with IC50 values ranging from 43.5-79.6 μM. Compounds 6, 7, and 11 protected HT22 hippocampal cells from glutamate-induced cell death, with EC50 values of 38.9, 14.8, and 27.1 μM, respectively.

Abstract
Two new triterpenoid glycosides, mimengosides H (1) and I (2), were isolated from the fruits of Buddleja lindleyana Fort. Their structures were determined by extensive spectroscopic methods. Neuroprotective effects of these isolates against 1-methyl-4-phenylpyridinium ion-induced neurotoxicity in PC12 cells were evaluated. Pretreatment with compound 1 had potential protective effect in a concentration range from 0.1 to 1 μmol l⁻¹.
