Frequently asked questions

05) How many unique molecules are contained in each extract of the library?

This question is much debated in the field, and a consensus answer is yet to emerge.

However, estimates of the average number of distinct compounds present within a crude plant extract range from hundreds to thousands [1].

The entire Phytotitre library may therefore contain thousands to hundreds of thousands of structurally distinct compounds - far greater than a synthetic compound library of equivalent size.
