Drug research is an important part of pharmaceutical field especially in Ayurveda pharmaceutics to revalidate and establish various formulations. Ghritha kalpana has got prime importance due to a special property of Ghritha i.e Samskarasyanuvartana. Ksheera ghritha and Ghritha are explained with different properties in Ayurveda classics. Present study is to compare between Yastimadhu Ksheera ghritha and classical Yastimadhu ghritha by organoleptic and analytical parameters. Ksheera ghritha procedure may bypass the long procedure , maximise the percentage of extract in Ghritha. Reference of Ksheera ghritha is available in various classical texts like Sushruta samhitha1 etc. Ksheera ghritha said to have properties like Netrya , Sangrahi , Rakthapitta hara etc. Ksheera ghritha of Yastimadhu prepared by preparing Ksheerapaka taken as G1 and Yastimadhu Ghritha prepared by normal classical way taken as G2. Analytical study for standardization of both samples were carried out on the basis of classically illustrated organoleptic tests and modern parameters of physico-chemical properties like LOD, Refractive index , Saponification value etc., and TLC done for qualitative analysis. By this study the major difference between Ksheera ghritha and Ghritha are established giving further scope for clinical research to establish efficacy of same. KEY WORDS : Ayurveda, Ghritha, Yastimadhu, Ksheerapaka.

Refractive Index Data

Modelling the optical and radiative properties of atmospheric particles is governed by one of the key input parameters, i.e., the refractive index of aerosols. Availability of the region-specific refractive index data of aerosols is a major challenge for the atmospheric community. The refractive index of aerosols is a function of their physico-chemical properties. Uncertainty in the computation of the spectral refractive indices of aerosols leads to erroneous assessment of their optical and radiative properties. In the present work, the refractive indices of pure clay (kaolinite, illite) and polluted clay with anthropogenic hematite, AH (0.10 to 1.48%) submicron particles have been computed for the wavelength range of 0.38 to 1.2 µm. Anthropogenic hematite enhanced the overall absorption in the UV and visible range with maximum absorption at lower wavelengths (less than 0.55 µm).

Due to the high demand for vegetable oil by soap industries, the quest for alternative raw material is on the increase. In this study, vegetable oil was extracted from the underutilise seeds of Lagenaria siceraria using n-hexane; The Physico-chemical properties of the oil were analysed: iodine value 65 Ig/100 g, acid value 2.50 mg/KOH/g, saponification value 256 mgKOH/g, pH 6.20, specific gravity 0.902, the refractive index of 1.47 and oil yield 52%. The properties of the oil were compared with oil extracted from other sources. The properties of the oil suggest it can use for both commercial and industrial purposes. The extracted oil was then used to prepared soap and its properties were compared with the properties of soaps prepared from other oils. The physicochemical parameters of the prepared soaps which include foam height, hardness, pH and cleansing power were evaluated. The soap made from Lagenaria siceraria seeds oil has foam height of 2.0 cm lower than palm kernel oil (2.1 cm) and higher than soya beans (0.55 cm). Soap made from Lagenaria siceraria seed oil has an appreciable degree of hardness and good cleansing power compared to soaps prepared from other oils. The pH of all the soaps prepared is within the standard of the regulating agency in Nigeria. From the result obtained, it shows the underutilised Lagenaria siceraria seed oil can use as an alternative raw material in the commercial production of soap.

Some important physico-chemical properties of water of major ponds of Comilla Town were studied to evaluate the water quality. Eight water samples were collected during the dry period (March 2005) from eight major ponds of Comilla Town (Ranir dighi, Mandir dighi, Nanuar dighi, Fauzdari dighi, Modina dighi, Dargabari dighi, Darma Sagar and Thakurpara). The result revealed that all the chemical constituents, except a few, are beyond the recommended limit for different uses. Higher value of pH (at Dargabari dighi, Darma Sagar dighi), OM (at Thakurpara dighi, Fauzdari dighi and Modina dighi), NH4+ concentration (at Ranir dighi, Mandir Dighi, Fauzdari dighi, Modina dighi and Dargabari dighi), and lower value of DO (at Fauzdari dighi and Modina dighi) may due to continuous disposal of kitchen wastes, organic wastes, sewage running and fall of twigs as well as extensive used for bathing, washing cloths and utensils etc. All indicate eutrophication and affect community health and hygiene and also create aesthetic problem in the locality.

: In the present study the applicability of various molecular descriptors was tested for the QSPR study on 40 quinolones derivatives. The relationship between some of the molecular indices with physicochemical properties such as refractive index (n), polarizability (α) and HOMO-LUMO energy gap (ΔEH-L) was represented. At first, the chemical structure of quinolones derivatives was optimized by Gaussian 98 program and ab initio method at the #HF/6-31++G**level, and then the physicochemical properties such as refractive index, polarizability and HOMO-LUMO energy gap were calculated. Genetic algorithm using multiple linear regression (GA-MLR) with backward method by SPSS software was used for obtaining properties. The analytical powers of the established theoretical models were discussed using leave-one-out (LOO) cross-validation technique. A multi-parametric equation containing maximum three descriptors with suitable statistical qualities was obtained for predicting the studied properties.

Abstract The major objective of this study is to report physico-chemical properties of sunflower oil samples collected from different stages of the technological process for sunflower oil refining for food industry. The samples of oil were crude oil, washed oil, bleached oil and deodorized oil. The physico-chemical properties of sunflower oil experimentally determined were density, saponification value (SV), iodine value (IV), and acid value (AV). It was found that the density of sunflower oil remains approximately constant over the different stages of the manufacturing flow of cooking oil, except the crude oil. The acid value significantly decreases from crude oil (2.588) to deodorized oil (0.366). The iodine value and saponification value of the different samples of the sunflower oil corresponding to different stages of oil processing varies slightly. The capacity of different models to accurately correlate and/or predict the density of vegetable oil was tested. The density of sunflower oil can be accurately estimated from its SV and IV or with an empirical equation, when density data are available.
