FRACTIONATION OF THE CHLOROFORM EXTRACT OF MAPLE SYRUP
Canadian Journal of Research, 1939A method of fractionating the chloroform soluble constituents of maple syrup has been devised. Marked differences were observed among Quebec syrups of different years. Fat constituted half the weight of the extract of the 1935 syrup but was completely absent in the 1936, and present in very small quantity in the 1937, product.

Chloroform–Methanol Extraction of Chlorophylla
Canadian Journal of Fisheries and Aquatic Sciences, 1985Chloroform–methanol (2:1, v/v) extracts significantly more (P < 0.001) chlorophyll a from algal cultures and from freshwater and seawater microcosms than does dimethyl sulfoxide, methanol, absolute methanol with hydrogen sulfide, or 90% acetone. For chlorophyte cultures it yields 97% or more of the chlorophyll a within a 4-h steeping period without ...
