    preparation is a noun, so 2 would be [noun]+[adjective]+[noun phrase], which isn't grammatical

1 Answer 1


These are rather phrases than sentences but it does not matter for all practical purposes.

The first is correct:

Preparation of medicinal plant extract.

In the second, you need to change word order as someone has already suggested in the comments:

Medicinal plant extract preparation.

However, it still sounds a bit awkward as such a long subject is difficult to comprehend, so if I were you I would go with the first sentence.

Generally, such transformations between A of B and B/(adjective from) B A often exist:

Bombers of WWII <-> WWII bombers.
States of Europe <-> European states
The US constitution ratification <-> The ratification of the US constitution
