摘要：

Carrageenans present in an alga can be identified rapidly by FT IR diffuse reflectance spectroscopy directly on only a few milligrams of dried, ground algal material, hence avoiding lengthy extraction procedures. Not only are the major types of carrageenans (such as kappa-, lambda-, and iota-carrageenans) detected, but so are smaller fractions (such as the precursors mu-, nu-, and omicron-carrageenans). Because the samples are minimally treated, the determined composition represents, as accurately as possible, the natural composition of the plants.
