The results showed that the gross caloric values (GCV) of Butia capitata in various components can be ranked in the decreasing order as follows: mature leaves>lower roots>young leaves>upper roots>rhizome>petioles; for Acoelorraphe wrightii, the order was: mature leaves>upper roots>lower roots>young leaves>petioles; for E. guineensis, the order was: mature leaves>upper roots>lower roots>young leaves>petioles>rhizomes. The ash free caloric values (AFCV) in different components also varied widely, and could be ranked almost in the same order as those of GCV. B. capitata ash contents in various components could be ranked in a decreasing order as follows: lower roots>upper roots>rhizomes>young leaves>petioles>mature leaves; for A. wrightii, the order was: young leaves>mature leaves>lower roots>upper roots>petioles; for E. guineensis, the order was: mature leaves>young leaves>lower roots>upper roots>petioles>rhizomes. The results indicated that the cold resistant B. capitata has a more reasonable distribution of caloric values and ash contents, this character may help to improve its adaptation to the low temperature
