Title: Regeneration of the carbonyl compounds from their semicarbazones using tetra-n-alkylammonium bromates Authors: Baruah, Akashi; Nath, Utpal; Das, Satya Sandhya; Das, Pranab Jyoti Abstract: Tetra alkyl ammonium bromates are prepared by a simple procedure and used for the oxidative regeneration of the parent carbonyl compound from their semicarbazones. Reaction conditions are simple and the deprotection gives satisfactory yield of the carbonyl compound. Page(s): 2157-2160

Title: 10-Methyl-n-heptacosane and diglucosyldirhamnoside from the stem bark of Balanites aegyptiaca Delile Authors: Ansari, M M; Ahmad, J; Ali, M; Ansari, S H Abstract: A new long chain aliphatic compound, 10-methyl-n-heptacosane and a new sugar, diglucosyldirhamnoside have been isolated from the ethanolic extract of the stem bark of Balanites aegyptiaca. The structures of these compounds were elucidated by a combination of spectral methods (lR, MS, ^IH and ^I3C NMR). Page(s): 2154-2156
