Abstract
We have worked on the research related with total flavonoid isolated Rhododendron
Adamsii Rehder, which enhance and restore physical energy and reduce mental pain. According to
the result, the highest amount (2.4±0.007%) of the total flavonoids was found in the 40% ethanol
extract of Rhododendron Adamsii Rehder at 60 minutes of extraction time. Subsequently, the
granulated formulation from the extract of Rhododendron Adamsii Rehder was prepared by using
4% of gelatin, 4% of polyvinylchloride and 4% of carboxymethyl cellulose. The fluidity and pouring
weight of the granule was evaluated and 4% of gelatin was chosen as the suitable binder for
the formulation. In conclusion, we have successfully developed the granulated formulation from
Rhododendron Adamsii Rehder.
