A new cembrane-type diterpenoid from Bornean liverwort Chandonanthus hirtellus.
A new compound, chandonanol (1), along with four known compounds, chandonanthone (2), iso-chandonanthone (3), anastreptene (4), and (6R,7S)-sesquiphellandrene (5), was isolated from the MeOH extract of Bornean liverwort Chandonanthus hirtellus. The structure of the new metabolite was established by analyses of the spectroscopic data (1D NMR, 2D NMR, HRESIMS, and IR). These compounds were tested...
متن کاملA new norsesquiterpenoid from a Bornean soft coral genus Nephthea.
A new germacrane-type norsesquiterpenoid, 1-acetoxy-germacra-5E,10(14)-diene-4-one (1), as well as three known compounds, were isolated from the organic extracts of a Bornean soft coral Nephthea sp. Their structures were elucidated on the basis of spectroscopic data analysis.
متن کاملNew Laurene-type Sesquiterpene from Bornean Laurencia nangii.
We report the chemical composition of a population of Bornean Laurencia nangii Masuda. A new compound, neolaurene (1), along with five known metabolites, neolaurallene (2), 2,10-dibromo-3-chloro-α-chamigrene (3), deoxyprepacifenol (4), cycloelatanene B (5) and intricatetraol (6), were isolated and their chemical structures elucidated based on spectroscopic data. In addition, their cytotoxicity ...
متن کاملTaxonomy of the Bornean slow loris, with new species Nycticebus kayan (Primates, Lorisidae).
More species of nocturnal primates are now recognized than in the past, because many are cryptic species. Subtle morphological disparities, such as pelage pattern and color variation, vocal cues, and genetics have aided in elucidating the number of diagnosable species in a genus. The slow lorises (genus Nycticebus) once included only two species, but recent taxonomic studies resulted in the des...
متن کاملon the comparison of keyword and semantic-context methods of learning new vocabulary meaning
the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...
