• Question

  Hello again! I see that watermelon still has no specific constituent. And I've heard of cucubocitrin telling it might be the one responsible for the plant's diuresis. But I also have read one article telling that there is this cucurbitacin (is this the same with cucurbocitrin?) which has diuretic property. but i just can't find more articles regarding this matter.

  Answer

  Dear bananinah, I can't answer your question concerning the active constituent that produces diuresis--but I can help you with your other question. Cucurbocitrin and curcubitacin are not the same kinds of compounds. Cucurbotricin is a glucoside-saponin and cucurbitacin is a steroid. Therefore, I believe these items are different compounds (i.e., not the same compound with two different names). Best wishes.
