不 is used to negate buying as a general action, habit, choice, or future intention.
- 我不买任何辣椒。 = I do not buy any chili peppers / I won’t buy any chili peppers.
- 我没买任何辣椒。 = I did not buy any chili peppers.
A simple way to remember it:
- 不 = not, generally or habitually
- 没 = did not, or have not
So if you are talking about something you usually do not do, or something you are refusing to do now, 不 is the right choice.
任何 means any in the sense of any at all.
In this sentence, 任何辣椒 means any chili peppers whatsoever. It strengthens the negation.
So:
- 我不买辣椒。 = I don’t buy chili peppers.
- 我不买任何辣椒。 = I don’t buy any chili peppers at all.
A very important point: 任何 is most commonly used in negative sentences, questions, and some conditional sentences.
Examples:
- 我没有任何问题。 = I don’t have any questions.
- 你有任何问题吗? = Do you have any questions?
- 如果有任何问题,请告诉我。 = If there are any problems, please tell me.
