Production of anti-tumor-promoting iridoid glucosides in Genipa americana and its cell cultures.

The Genipa americana plant contains geniposide [3] and geniposidic acid [2] in the fruits and geniposidic acid [2] in the leaves. On callus induction, the plant produces tarennoside [1], geniposidic acid [2], and gardenoside [4] in high levels. The leaves of Ge. americana plants redifferentiated from the callus tissues produce 2.
