Molecular record for the first authentication of from Vietnam.

The entomopathogenic fungus T011, parasitizing on nymph of Cicada, collected in the coffee garden in Dak Lak Province, Vietnam, was preliminarily morphologically identified as , belonged to order Hypocreales and family Clavicipitaceae. To ensure the authenticity of T011, phylogenetic analysis of the concatenated set of multiple genes including , , , , and was applied to support the identification. Genomic DNA was isolated from dried sample T011.

Pipercyclobutanamide D, a new member of the cyclobutanamide-type alkaloid, from the roots of .

From the EtOH-soluble extract of the roots of , one new dimeric alkamide, pipercyclobutanamide D () was isolated. Its structure was elucidated on the basis of NMR spectroscopic interpretation. The relative configuration of was determined based on the NOESY analysis.
