prepared and evaluated on their stability and
preference.
All of the base lotions retained their
homogeneity followings centrifugation assays.
Thus, all of them were evaluated under
accelerated tests. All of the base lotions were
homogeneous white with opaque and smooth
texture as appeared in the initial state with the
consistence of pH and viscosity as shown in Table
3. They were further evaluated on performance. It
was found that base no. 4 was the most
preference. Therefore, base lotion no. 4 was
chosen for incorporation of the extract at IC50, two
and three folds of IC50 of the best antioxidant
fraction and labeled as formula A, B and C
respectively.
All of the developed formulas passed
centrifugation assays and further evaluated by
accelerated test. Chemical stability was tracked
by the total phenolics content and all of the 3
developed formulations were found chemically
and physically stables (Table 4).
CONCLUSION: Tamarind seed coated extracts
posed high antioxidant activity as well as total
phenolics content particularly the EtOAc extracts
from either partition or maceration. This practical
and economical extraction is ease for operation
and applications. The finding relationship of the
active principle compounds and biological activity
is available for quality control of the extracts and
