Brahmi Ghrita was processed as per the process of Snehapaka procedure described in classics. It contained Brahmi (Bacopa monneri), Vacha (Acorus calamus), Kushtha (Sassurea lappa), Shankhapushpi (Convolvulos pluricalis), and Purana Ghrita. In the preparation of Brahmi Ghrita, Brahmi Swarasa, Kalka Dravya of Brahmi, Vacha, Kushtha, and Shankhapushpi were mixed in Purana Ghrita and heated for three hours at 110°C every day for three days. On the third day Ghrita was filtered to obtain the finished product. In this manner, three samples of Brahmi Ghrita were prepared. To understand the changes that occurred during the preparation, Brahmi Ghrita and Purana Ghrita were analyzed by using modern parameters such as Acid value, Saponification value, and so on. After the analysis, it was found that the Acid values of Sample A, B, and C of Brahmi Ghrita were 4.26, 4.03, and 4.03; the Saponification values of Samples A, B, and C of Brahmi Ghrita were 227.2, 230.01, and 230.01, and the Iodine values of Samples A, B, and C were 34.75, 35.88, and 35.88, respectively, and the Acid value, Saponification value, and Iodine value of Purana Ghrita were 1.57, 199.15, and 31.04, respectively. The present study revealed that, there was no significant variation in the analytical values among all three samples of Brahmi Ghrita. [ABSTRACT FROM AUTHOR]

The present work has developed a straightforward, gentle, and effective approach for synthesizing arylamines and 5-substituted-1 H -tetrazole derivatives, and among the two tested catalysts, molybdenum trioxide (MoO 3 ) proved to be highly effective. The selective hydrogenation of nitroarenes to arylamines presents a significant challenge due to the complex reaction mechanism and the competitive hydrogenation of other reducible functional groups. It facilitated the transfer hydrogenation of nitrobenzene using hydrazine hydrate-produced amino compounds and enabled the [3 + 2] cycloaddition of sodium azide with aromatic nitriles to yield 5-substituted-1 H -tetrazoles. The structure of compound 5-(4-bromophenyl)-1 H -tetrazole (5k) was verified through single-crystal X-ray analysis, and the calculation of Green Chemistry Metrics showed the optimal range. Notably, the MoO 3 catalyst can be reutilized for up to seven cycles with minimal loss of effectiveness. These attributes make molybdenum trioxide particularly attractive for industrial applications. This methodology offers several advantages over traditional synthetic methods., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (This journal is © The Royal Society of Chemistry.)

The title compound, C(15)H(9)ClO(2), is a synthetic flavonoid obtained by the cyclization of 3-(4-chloro-phen-yl)-1-(2-hy-droxy-phen-yl)prop-2-en-1-one. The 4-chloro-phenyl ring is twisted at an angle of 11.54° with respect to the chromen-4-one skeleton. In the crystal, pairs of mol-ecules are inter-connected by weak Cl⋯Cl inter-actions [3.3089 (10) Å] forming dimmers which are further peripherally connected through inter-molecular C-H⋯O hydrogen bonds.

In the title compound, C(10)H(8)N(2)S, the 2-amino-benzothia-zole and propyne groups are not coplanar [dihedral angle = 71.51 (1)°]. The crystal structure is stabilized by strong inter-molecular N-H⋯N hydrogen bonds and C-H⋯C, C-H⋯π and F-type aromatic-aromatic [centroid-centroid distance = 3.7826 (12) Å] inter-actions are also observed.

The title compound, C(15)H(11)Cl(2)NO, is approximately planar (r.m.s. deviation = 0.062 Å) and contains a single C=C double bond in a trans (E) configuration. The crystal packing is stabilized by intermolecular N-H⋯N and N-H⋯O inter-molecular hydrogen bonding.

In the crystal of the title compound, C(17)H(20)N(2)O(2), the molecules are linked by C-H⋯O interactions. Intra-molecular C-H⋯O and N-H⋯N hydrogen bonds also occur.

The title compound, C(14)H(11)ClFNO(2), the phenyl ring (A), the chloro-fluoro-phenyl ring (B) and the central ketone O/C/O group (C) are not coplanar, with dihedral angles B/C = 31.6 (2), A/B = 21.3 (2) and A/C = 50.1 (2)°. The crystal packing is stabilized by N-H⋯O and C-H⋯O inter-actions.
