Physico-chemical Characteristics of Oil and Seed Residues of Bauhinia variegata and Bauhinia linnaei
Physico-chemical characteristics of two Bauhinia seed varieties (B. variegata and B. linnaei), were evaluated for commercial exploration. Physico-chemical characteristics of the oils for both varieties were demonstrated and mean values found to be refractive index (40 °C) 1.4589 and 1.4588, peroxide...

Physico-chemical characteristics of two Bauhinia seed varieties (B. variegata and B. linnaei), were evaluated for commercial exploration. Physico-chemical characteristics of the oils for both varieties were demonstrated and mean values found to be refractive index (40 °C) 1.4589 and 1.4588, peroxide value 1.9 and 2.4 (meq O2 / kg of oil), iodine value 84.5 and 92.2 (g of I2/100g of oil), saponification number 191.3 and 195.5 (mg of KOH /g of oil), free fatty acids 0.6% and 0.9%, unsaponifiable matter 0.9% and 1.2% and color (1 in. cell), 2.2-2.9R + 30.0-25.0Y, respectively.
