New sesquiterpenoid from the mushroom Sparassis crispa.
A new sesquiterpenoid (1) was isolated from the mushroom, Sparassis crispa, along with a known sesquiterpenoid (2). The structure of 1 was determined as (3R(*), 3aS(*), 4S(*), 8aR(*))-3-(1'-hydroxy-1'-methylethyl)-5,8a-dimethyldecahydroazulen-4-ol by the combination of NMR and ESI-MS analyses.
متن کاملAntimicrobial activity and chemical composition of the essential oil of Nepeta crispa Willd. from Iran.
The composition and antimicrobial activity of the essential oil of Nepeta crispa Willd., an endemic species from Iran, was studied. The oil was obtained from the aerial parts of the plant and analyzed by GC and GC/MS. Twenty-three compounds, accounting for 99.8% of the total oil, were identified. The main constituents were 1,8-cineol (47.9%) and 4aalpha,7alpha,7abetanepetalactone (20.3%). The a...
متن کاملAnticholinesterase inhibitory activity of quaternary alkaloids from Tinospora crispa.
Quaternary alkaloids are the major alkaloids isolated from Tinospora species. A previous study pointed to the necessary presence of quaternary nitrogens for strong acetylcholinesterase (AChE) inhibitory activity in such alkaloids. Repeated column chromatography of the vine of Tinospora crispa extract led to the isolation of one new protoberberine alkaloid, 4,13-dihydroxy-2,8,9-trimethoxydibenzo...
متن کاملCytotoxic and apoptogenic effects of Strobilanthes crispa Blume extracts on nasopharyngeal cancer cells.
The chemotherapeutic agents used to treat nasopharyngeal cancer (NPC) exhibit low efficacy. Strobilanthes crispa Blume is widely used for its anticancer, diuretic and anti‑diabetic properties. The present study aimed to determine the cytotoxic and apoptogenic effects of S. crispa on CNE‑1 NPC cells. A 3‑(4,5‑dimethylthiazol‑2‑yl)‑2,5 diphenyl tetrazolium bromide assay was used to evaluate the c...
