Cembranoids from Boswellia species
Phytochemistry, 2021Frankincense of Boswellia species has long been used in traditional medicines, mainly for its interesting anti-inflammatory and anti-depressant properties of its di- and triterpenes. Boswellic acids (triterpenes) and cembranoids (diterpenes) are the major constituents of frankincense from all reported species which are responsible for the overall ...

Abstract Three new cembranoids, dihydroplexaurolone (2) and two dehydroplexaurolones (3) and (4), have been isolated from the gorgonlan Plexaura A. The structure of 2 was established by X-ray crystallographic studies. Crystals of 2 belong to space group P21, with a = 10.711 (2) A, b = 10.976 (3) A, c = 17.148 (4) A, β = 99.99 (2)°, and Z = 4.

Cembranoid diterpenes from soft coral Sinularia sp.
China Journal of Chinese Matera Medica, 2010A soft coral Sinularia sp., collected from the South China Sea, was selected to investigate the bioactive and chemical constituents. The EtOAc fraction were isolated by repeatedly silica gel and Sephadex LH-20 column chromatography to obtain lobophytolide A (1), 3-dehydroxylpresinularolide B (2), sarcophine (3), 3 beta-acetoxyisolobophytolide (4 ...

[A new cembranoid diterpene from Olibanum].
Zhongguo Zhong yao za zhi = Zhongguo zhongyao zazhi = China journal of Chinese materia medica, 2022Five compounds were isolated from the alcohol extract of Olibanum by MCI, silica gel, ODS, and Sephadex LH-20 column chromatographies and preparative high-performance liquid chromatography(HPLC). On the basis of spectral data and literature data, the compounds were identified as:(1S,3R,4S,7R,11S,12R)-1:12,4:7-diepoxisonane-8(19)-ene-3,11-diol(1 ...
