Isolation and identification of allelochemicals from Ophiopogon Japonicus: A candidate for allelopathic ground cover plants

Antimicrobial activities of endophytic fungi isolation from Ophiopogon japonicus

Antimicrobial activities of endophytic fungi isolated from Ophiopogon japonicus (Liliaceae)

BACKGROUND Drug resistance in bacteria has become a global concern and the search for new antibacterial agents is urgent and ongoing. Endophytes provide an abundant reservoir of bioactive metabolites for medicinal exploitation, and an increasing number of novel compounds are being isolated from endophytic fungi. Ophiopogon japonicus, containing compounds with antibacterial activity, is a tradit...

2-Benzyl-benzofurans from the tubers of Ophiopogon japonicus

BACKGROUND The overproduction of nitric oxide (NO) is known to involve in various inflammatory processes. A methanol extract of the tubers of Ophiopogon japonicus was found to strongly inhibit NO production. The present paper deals with the isolation, structural identification and NO inhibitory effect of five compounds isolated from the MeOH extract of O. japonicus tubers. RESULTS Three new c...

Isolation and Characterization of the Betaine Aldehyde Dehydrogenase Gene in Ophiopogon japonicus

Betaine aldehyde dehydrogenase (BADH) catalyzes the last step in the synthesis of the glycine betaine from choline. The BADH gene from turfgrass Ophiopogon japonicus has not been reported. In this study, we first isolated the full length cDNA of betaine aldehyde dehydrogenase gene (OjBADH) from O. japonicus using Reverse TranscriptasePolymerase Chain Reaction (RT-PCR) and Rapid Amplification of...

Homoisoflavonoids and the Antioxidant Activity of Ophiopogon japonicus Root

The root of Ophiopogon japonicus has been used as a traditional Chinese medicine and also a functional food ingredient for a long time in China. In the present study, 17 different homoisoflavonoid compounds were identified in the root extract of O. japonicus by HPLC–DAD and LCMS/MS analyses. The antioxidant activity of the of chloroform/methanol (1:1, v/v), methanol and 70% ethanol extracts, an...
