Dendrophthoe falcata (LINN. f.) ETTING. (Syn: Loranthus longiflorus DESR., Loranthus falcatus LINN. f.; Fam. Loranthaceae) is known as 'Vanda' in the Indian Ayurvedic System of Medicine. 1) D. falcata is a large bushy parasitic plant that grows on a variety of host plants in deciduous forests throughout India.2) The entire plant is medicinally important and is used extensively in traditional medicine as an aphrodisiac, astringent, narcotic, diuretic, and for the relief of asthma, menstrual disorders, and pulmonary tuberculosis.3) It is interesting to note that the medicinal properties of this parasitic plant are greatly influenced by the host plant. For example, when grown on Calotropis gigantea, this parasitic plant is considered useful for improving cognitive function. However, when D. falcata is grown on Tamarindus indicus, it is used to treat impotence, 4) and the plant grown on Shorea robusta (Sal tree) is used to treat paralysis by the tribes of the Bihar state of India.5) In addition to its medicinal value, the fruit of D. falcata tastes sweet and is consumed as a food. 6)

LlQUID-LIQUID extraction is a common method used in the recovery of tar-acids from the effluents of carbonization, coke oven, and other plants. Phenosolvan which is a mixture of butyl, propyl, amyl, and hexyl acetates, and boils in the range from 110°to 130°C. (4), is a solvent successfully used in industry. Certain other esters and ketones also show high partition coefficients for tar acids (7). To select the best solvent or solvent mixture and to assess the performance of liquid/liquid extractors, a detailed knowledge of the phase behavior of the ternary system of pure substances involved is necessary.Therefore, it was decided to determine solubility and equilibrium data for systems involving different tar acids and solvents like butyl acetate, amyl acetate, methyl
