More than 90% of the cyanogenic compound is stored in the endosperm. During seedling development under aseptic conditions HCN-p of the entire seedling decreases to 15% within 19 days. The cyanogenic compounds are metabolized during germination to form noncyanogenic substance. Leaves of Hevea pauciflora, H. benthamiana, H. pauciflora x H. bentamiana and H. spruceana contain both linamarin and (R)-lotaustralin, whereas lotaustralin was not detectable in leaves and seeds of H. brasiliensis.  acyanides  aCianeto  aEspécie  aHevea  aSeringueira  aRubber tree  aSpecies1 aNAHRSTEDT, A.1 aSELMAR, D.1 aGASPAROTTO, L.  tPhytochemistrygv. 25, n. 7, p. 1573-1578, 1986.
