Black Sea sterol—a molecular fossil for dinoflagellate blooms
Jaap J. Boon,W. Irene C. Rijpstra,Frits De Lange,J.W. de Leeuw,Masako Yoshioka,Yuzuru Shimizu +5 more
TL;DR: A PECULIAR sterol has been found in recent sedimentary environments which was found was identical with the Black Sea sterol and its significance was discussed.

Sterols as source indicators of organic materials in sediments
Huang Wen-Yen,W. G. Meinschein +1 more
TL;DR: The sterol contents of plankton and sediment samples have been determined as mentioned in this paper, showing that 34% of the sterols in the Gulf sediments are derived from terrigenous sources.

Influence of chemical refining on the major and minor components of rice brain oil
TL;DR: In this paper, the effects of each individual step of the chemical refining process on major and minor components of rice bran oil were examined, and the results showed that rice brain oil contains a significantly higher level of several bioactive minor components such as γ-oryzanol, tocotrienols, and phytosterols.
Journal ArticleDOI
Sterols of the phytoplankton—effects of illumination and growth stage
TL;DR: The effect of culture age in the cultured specimen; was examined by harvesting in both the exponential and stationary growth phases and was found to produce considerable differences in the sterol composition in some species.

Younus M. Sheikh,Carl Djerassi +1 more
TL;DR: The sponges Stelleta clarella, Tethya aurantia, Lissodendoryx noxiosa, Haliclona permollis and Halic lona sp. were examined for steroids as mentioned in this paper.
