A new bibenzyl from Dendrobium secundum.
From the aerial parts of Dendrobium secundum, a new bibenzyl, namely 4,5,4'-trihydroxy-3,3'-dimethoxybibenzyl, was isolated, along with four known compounds which included brittonin A, moscatilin, syringaresinol, and ferulic acid. All of these isolates showed appreciable DPPH free radical scavenging potential, except for brittonin A, which was devoid of activity.
متن کاملSubchronic and Genetic Safety Assessment of a New Medicinal Dendrobium Species: Dendrobium Taiseed Tosnobile in Rats
Dendrobium Taiseed Tosnobile is a new species of herba dendrobii (Shi-Hu) that was developed by crossbreeding D. tosaense and D. nobile. Its pharmacological activity and active component have been reported, but its subchronic toxicity and genetic safety have not yet been investigated. This study assessed the 90-day oral toxicity and genetic safety of the aqueous extracts of D. Taiseed Tosnobile...
متن کاملCytotoxic and Antifungal Constituents Isolated from the Metabolites of Endophytic Fungus DO14 from Dendrobium officinale.
Two novel cytotoxic and antifungal constituents, (4S,6S)-6-[(1S,2R)-1, 2-dihydroxybutyl]-4-hydroxy-4-methoxytetrahydro-2H-pyran-2-one (1), (6S,2E)-6-hydroxy-3-methoxy-5-oxodec-2-enoic acid (2), together with three known compounds, LL-P880γ (3), LL-P880α (4), and Ergosta-5,7,22-trien-3b-ol (5) were isolated from the metabolites of endophytic fungi from Dendrobium officinale. The chemical structu...
متن کاملNew human papilloma virus isolated from epidermodysplasia verruciformis lesions.
Human papilloma virus (HPV) was isolated from red plaques of a patient (N. F.) with epidermodysplasia verruciformis. Electron microscopic examination showed characteristic particles of papilloma virus as icosahedrons about 45 nm in diameter. DNA was extracted from these particles, and closed-circular DNA (Form I) was purified by centrifugation in CsCl containing ethidium bromide. The molecular ...
