Abstract:

We isolated leaf mucilage from Litsea quinqueflora (Dennst.) Suresh, a plant that belongs to the Lauraceae family. Leaves of L. quinqueflora are medicinally important as the traditional healers of Kerala use it in different inflammatory conditions. Various analytical methods such as Fourier transform infra-red analysis, Powder X-ray diffraction pattern, scanning electron microscopy, thermogravimetry analysis, and differential scanning calorimetry were done to characterize the leaf mucilage of Litsea (LML). The results revealed the thermal stability, amorphous nature, aggregate structure, and polysaccharide nature of LML. The evaluation of antioxidant property of LML revealed significant activity against free radicals such as DPPH and ABTS with P ≤ 0.001. LML is exhibiting an IC 50 value 97.8 μg/ml by inhibiting protein denaturation and thus revealed significant anti-inflammatory potential with P ≤ 0.01. The dye adsorption capacity of LML in aqueous media against malachite green and methylene blue showed its role in phytoremediation.
