Antimicrobial and anti-acetylcholinesterase activities of secondary metabolites isolated from MNY-14.

A systematic investigation of the secondary metabolites of MNY-14, which was isolated from the ripe leaves of , led to the isolation of eighteen compounds, including twelve indole diketopiperazine alkaloids (-), an -pyrone meroterpenoid (), a nortriterpenoid (), two benzophenones (), and two quinoline alkaloids (). Among them, compounds , and were isolated for the first time from . The chemotaxonomic significance of the secondary metabolites was discussed.

Accumulation of antitumor polyketides by fermentation of Rubus delavayi Franch. with Clonostachys rogersoniana.

The aim of this work is to explore the effects of herbal medicine on secondary metabolites of microorganisms during fermentation. Clonostachys rogersoniana was found to metabolize only small amounts of polyketide glycosides rogerson B and C on fresh potatoes, but after replacing the medium to the medicinal plant Rubus delavayi Franch., the type and content of the metabolized polyketones showed significant changes.

Guided isolation of secondary metabolites from Nectria sp. MHHJ-3 by molecular network strategy.

The fungus Nectria sp. MHHJ-3 was isolated from Illigera rhodantha. A molecular networking-guided the secondary metabolites investigation of Nectria sp.

Steroids and dihydroisocoumarin glycosides from Xylaria sp. by the one strain many compounds strategy and their bioactivities.

The fungus Xylaria sp. KYJ-15 was isolated from Illigera celebica. Based on the one strain many compounds (OSMAC) strategy, the strain was fermented on potato and rice solid media, respectively.
