To study the chemical constituents of Pithecellobium clypearia. Silica gel column chromatography and Sephadex LH-20 were used to separate and purify compounds from the EtOAc soluble fraction of Pithecellobium clypearia. 9 compounds were elucidated on the basis of physicochemical properties
Journal of electron microscopy technique, 18(2), 142-147 (1991-06-01)
The crystal structure of the odd-chain paraffin, n-tritriacontane, nC33H68, is determined directly by using low-dose electron microscope images and electron diffraction intensity data from epitaxially grown microcrystals. Phases of the most intense "polyethylene" reflections are determined from triplet structure-invariant relationships

To study the chemical constituents of the root of Inula cappa. The compounds were isolated and purified by recrystallization and chromatography with silica gel column and Sephadex LH-20 column. Their structures were identified by physico-chemical properties and spectral analysis. Seven
About 50 years ago crystalline deposits of a substance representing approximately 7 per cent wet tissue weight and believed to be hentriacontane or a mixture of similar long-chain n-alkanes (30-34 carbon atoms) were detected in two discoloured and swollen cow
