In Ayurvedic medicine, herbs are used as an integral part of health care system. Besides healthcare, herbs are also used for beautification of the body and for preparation of various cosmetics and colours. The aim of present study involves preparation of poly herbal hair oil using fresh leaves of various plants. The prepared herbal oils were subjected to phytochemical screening, General characterization, Physical and Biological evaluation.The aim of present study involves preparation of poly herbal hair oil using fresh leaves of Sphaeranthus indicus, Wrightia tinctoria, Eclipta alba, Hibiscus Rosa sinensis. The oil was prepared according to Ayurvedic pharmacopeia. The evaluation of prepared poly herbal hair oil was carried out by various parameters such as organoleptic, phytochemical, specific gravity, pH, viscosity, acid value, saponification value, refractive index and stability studies. Antimicrobial activity of the poly herbal hair oil was studied by the zone of inhibition method. The Antioxidant activity of the oil was studied by DPPH radical scavenging test. The prepared formulations are assessed for primary skin irritation test on our forearm. Above parameters were found to be good and within the standards and among three concentrations of prepared poly herbal hair oil, third concentration showed better results than other two concentrations. All the values in the evaluation of finished product showed that they are within the acceptable limits. Hence, it is concluded that the oil is beneficial in maintaining good growth of hairs, turning grey hairs to black, providing protection from dandruff, and results in lustrous looking hairs.

Objective: The present method was proposed to develop a simple, sensitive, rapid, accurate and stability-indicating reverse phase-high performance liquid chromatographic (RP-HPLC) method for the simultaneous estimation of metformin and teneligliptin in pure and pharmaceutical formulations. Methods: The chromatographic separation was done on Discovery [250 mm X 4.6 mm: 5 μm is particle size] using a mobile phase composed of 0.1% orthophosphoric acid buffer: acetonitrile [65:35, v/v], the flow rate is 1 ml/min and the detection was carried out with a photodiode array (PDA) at 260 nm.Results: The retention time of metformin and teneligliptin were found to be 2.517 min and 3.687 min, respectively. Stability indicating studies were conducted under the guidelines of an international conference on harmonization [ICH] Q1A R2 and the developed method was validated as per the guidelines of ICH Q2 R1. The linearity was found in the range of concentration of 125-750 μg/ml and 5-30 μg/ml for metformin and teneligliptin. The lower limit of detection (LOD) and lower limit of quantification (LOQ) was found to be 0.02μg/ml and 0.07 μg/ml for metformin and 0.19 μg/ml and 0.56 μg/ml for teneligliptin, respectively.Conclusion: A novel stability-indicating reverse phase liquid chromatographic method developed for the simultaneous estimation of metformin and teneligliptin. The proposed method was adopted for the routine estimation of metformin and teneligliptin in bulk and pharmaceutical dosage forms.
Background To establish a simple, sensitive, accurate, precise, efficient, economical RP-UPLC method for simultaneous estimation of Doravirine, Lamivudine and Tenofovir disoproxil fumarate in bulk and their combined pharmaceutical formulations. Optimization of Chromatographic separation was achieved on analytical column HSS C18 (100 × 2.1 mm, 1.8 μ) maintained at temperature 30 °C and mobile phase consisting of 0.01 N Potassium dihydrogen orthophosphate buffer (pH-4.8) and acetonitrile in the ratio 60:40 v/v and at a flow rate 0.3 mL/min in isocratic mode. The injection volume was set as 1 µl detection wavelength is 260 nm. The proposed method validation was done as per International Council on Harmonization Q2 (R1) guidelines. Results Doravirine, Lamivudine and Tenofovir disoproxil fumarate were eluted at retention times of 1.2, 1.5, and 1.8 min respectively. The proposed method was identified an excellent linearity over concentration range of 12.5–75.0 µg/mL for Doravirine and 37.5–225.0 µg/mL for Lamivudine and 37.5–225.0 µg/mL for Tenofovir disoproxil fumarate. The percentage relative standard deviation for intra-day and inter-day precision of the present method was less than 2% for Doravirine, Lamivudine and Tenofovir disoproxil fumarate. Accuracy of the present method was evaluated by recovery studies which were in the range of 99.62–99.88% for Doravirine and 98.78–99.44% for Lamivudine and 99.67–100.52% for Tenofovir disoproxil fumarate. The limit of detection and limit of quantification were found to be 0.249 µg/mL and 0.756 µg/mL for Doravirine and 0.24 µg/mL and 0.727 µg/mL for Lamivudine and 0.797 µg/mL and 2.966 µg/mL for Tenofovir disoproxil fumarate. Forced degradation studies were carried out under various stress conditions like acid, base, peroxide, thermal, photo and neutral conditions. Conclusions The present method makes sure about no degraded impurity peak interference at the retention time of analyte peak hence can be applied for quality control investigation of Doravirine, Lamivudine and Tenofovir disoproxil fumarate in bulk and pharmaceutical formulations.

Objective: To evaluate antiplasmodial activity of Caesalpinia crista seed extracts Methods: Antiplasmodial activity of the seed extracts of Caesalpinia crista against rodent malaria infections in chloroquine sensitive Plasmodium falcipuram strain was investigated, and oral acute toxicity of seed extracts of Caesalpinia crista was also evaluated. Results: The findings of this study revealed significant (P < 0.05) and dose dependent decrease in parasitaemia in the parasitized groups treated with varying doses of the extract (50-200 mg/kg p.o.) in both suppressive and curative tests. There was also significant decrease in parasitaemia density in the chloroquine treated group. The alcoholic extract was found no toxicity in wistar rats and the oral LD50 was determined to be greater than 5000 mg/kg. Conclusion: Seed extracts of Caesalpinia crista extract possesses potent antiplasmodial activity and may therefore, serve as potential sources of new antimalarial agents Keywords: Plasmodium falcipuram, Caesalpinia crista, Plant extracts, Phytochemicals, Toxicity tests, malaria.
