Chemical composition of the rhizomes of Rhodiola rosea by the HPLC method

, : Chemical composition of the rhizomes of Rhodiola rosea by the HPLC method. Chemistry of Natural Compounds 27(2): 161-164

The main biologically active compounds found in the rhizome were salidroside, rosiridin and the cinnamyl glycosides rosavin, rosarin and rosin. The content of rosavin (cinnamyl vicianoside) in fresh rhizomes from roseroot stonecrop plants cultivated in Moscow province was ~2%. This decreased rapidly during storage of (incompletely dried) rhizomes and/or during pulping and extraction owing to autofermentation, reaching e.g. 0.29% after 30 min at 40 degrees C.
