• Employing the Ricinus communis plant fed with sodium hexanoate-1-14C (HA-1-14C) or sodium decanoate-1-14C (DA-1-14C), the distribution of the radioactive carbon and the convertibility of the radioactive fatty acid into the crude lipid were studied. In the plant treated with HA-1-14C, the recovery of the radioactivity was 9.25% in the whole, and 0.01% in the root, 3.04% in the stem, 0.05% in the leaf and 6.15% in the capsule, as well as in the one treated with DA-1-14C the recovery was 7.83%, and 0.01%, 1.66%, 0.02% and 6.14%, respectively. The recovery of the radioactivity in the lipid extracted from the organs of the plant treated with HA-1-14C was 6.0% in the whole, and 0.01% in the root, 0.97% in the stem, 0.04% in the leaf, 0.03% in the pericarp, 0.05% in the seed coat and 4.90/ in the embryo and endosperm, while the recovery of that treated with DA-1-14C was 5.29% and 0.01%, 0.79%, 0.03%, 0.12%, 0.04% and 4.30% respectively. The radioactivity incorporated in the lipid of the endosperm was distributed to the component fatty acids in the following ratio : nonhydroxy 14.16%, monohydroxy 81.69% and dihydroxy 3.01% in the case of treatment with HA-1-14C, while they were 12.93%, 81.85% and 3.98% with DA-1-14C, respectively. It was shown that there was no significant differences between the incorporation and the distribution of the radioactivity in Ricinus communis plant which was treated with HA-1-14C and DA-1-14C.
