"Chincha (Tamarindus indica Linn.), an extensively used material for culinary preparations in Indian civilization, has a vast medicinal value, emphasized in Ayurvedic classics as an independent medicine as well as a component of various formulations. Besides fruit being an important part, the Kasta (wood) is another part used specially for the purpose of Kshara (alkaline extract) preparation. Authentic published information regarding the pharmacognostical and physicochemical analysis of Chincha Kasta is not found in any of the works including in API (Ayurvedic Pharmacopoeia of India). Hence, an attempt
has been made for the first time in this direction. Various standardization parameters such as morphological characters, microscopic, physicochemical evaluations, TLC finger print, and fluorescence analysis of stem with heartwood were carried out. Transverse section of stem showed important characters such as phelloderm, stone cells layer, fiber groups, calcium
oxalate, crystal fibers, and tylosis in heartwood region. Four characteristic spots were observed under UV long wave, in thin layer chromatography with the solvent combination of toluene: ethyl acetate (8:2). These studies provide referential information for correct identification and standardization of this plant material."

The main objective of this present novel work is to investigate the performance, combustion and emission characteristics of biodiesel derived from the tamarind seed through the transesterification process as potential alternative feedstock for the diesel engine. The physio-chemical properties of tamarind seed methyl ester (TSME) were evaluated experimentally and compared with the base fuel. Test fuels were prepared in 3 concentrations such as B10 (10% tamarind seed oil and 90% diesel), B20 and B30.Experiments were conducted at a constant speed, the injection timing of 23° crank angle and compression ratio 17.5:1 with varying load conditions to investigate the diesel engine characteristics. TSME 20 shown better thermal efficiency (34.41%) over diesel which is 1.17 % higher and also it produces lower emissions of CO, HC, and smoke opacity. N-Amyl alcohol (NAA) is used as a fuel additive for the optimum blend of TSME20; added in 5% and 10% concentration on the volume basis. From the analysis of experimental data, the use of fuel additives significantly reduces the smoke opacity by 29.49 % for TSME20 NAA 10% blend in addition to the reduction of carbon monoxide and hydrocarbons emissions; however, the specific fuel consumption and the oxides of nitrogen were marginally increased.

Ribulose- 1, 5- bisphosphate carboxylase/oxygenase
otherwise known as Rubisco is a ubiquitous enzyme present in
almost all photosynthetic plants. Its physiological and
biochemical aspects have been extensively studied but little is
known about the molecular characterization in naturally
occurring plants. Tamarindus indica is a drought-tolerant
medicinal plant consumed for that purpose in the world
especially in Nigeria. Despite its belief to have medicinal
properties, there is limited information regarding the nutritional
and Rubisco contents particularly of the leaf and seeds. Here, the
bioactive compounds and Rubisco gene of the leaf and seed
extracts were characterised using aqueous extraction and gel
electrophoresis. The bioactive compounds varied differentially in
the leaves and seeds with glycosides, flavonoids, and alkaloids
present in both samples. Rubisco quantification showed that the
gene was lower in the leaf compared to the seed. The implication
of these responses in relation to carbon translocation is discussed.
