Abstract

Guava fruit tree is an important crop plant cultivated in Egypt. Guava leaf has a long history of folk medicinal uses in Egypt and worldwide as a cough sedative and as an antidiarrheal. It is also applied in the management of hypertension, obesity and in the control of diabetes mellitus in several countries. Recently it was introduced as a main ingredient in many herbal mixtures marketed in the Egyptian market and worldwide. It has been stated very often that the lack of standardization of herbal remedies and plant medicines is holding back the use of medicinal plants in the modern system of medicine, therefore a growing demand for the establishment of a system of standardization for every herbal preparation in the market is required and the buildup of a monograph containing all information required about the herbal drug is necessary. Therefore a monograph was designed on the basis set by the British Herbal Pharmacopeia in order to help in the quality control of the leaves. The monograph gave a full description of the leaf and powdered plant, summary of the activities and methods for the identification and the quality control of the raw material and the prepared extracts using physical, morphological, botanical and applying a validated HPTLC method for the quantification of Quercetin content.
