Python Pandas Extract text between words and symbols with regex

I am trying to extract certain words between some text and symbol using regex in Python Pandas. The problem is that sometimes there are non-characters after the word I want to extract, and sometimes there is nothing.

Here is the input table.

Here is the expected output.

I've tried this str.extract(r'[a-zA-Z\W]+\s+Reason to buy:([a-zA-Z\s]+)[a-zA-Z\W]+\s+') but does not work.

Any advice is appreciated.

Thanks.
