Vì điều kiện thời gian và vật chất hạn chế, nên trong phạm vi của bài khóa luận này, chỉ khảo sát một phân đoạn của cao etyl acetat.
Trong thời gian tới, chúng tôi sẽ tiếp tục tiến hành khảo sát thành phần hóa học và thử hoạt tính sinh học trên các phân đoạn cao còn lại của cao etyl acetat và các loại cao khác.
