Method development for Lawsone estimation in Trichup herbal hair powder by high-performance thin layer chromatography

A simple, specific, accurate, precise and robust high-performance thin-layer chromatographic method has been developed and validated for estimation of Lawsone in Trichup herbal hair powder (coded as a THHP), polyherbal formulation. The chromatographic development was carried out on aluminum plates pre-coated with silica gel 60F 254 and good resolution was achieved with Toluene: Ethyl acetate: Glacial acetic acid (8:1:1 v/v/v) as mobile phase. Lawsone detection was carried out densitometrically at 277 nm and obtained retardation factor value was 0.46 ± 0.02. The method was validated with respect to specificity, linearity, accuracy, precision and robustness. The calibration curve was achieved to be linear over a range of 5-60 μg/ml and regression coefficient was obtained 0.998. Accuracy of chromatographic method was evaluated by standard addition method; recovery was obtained 99.25 ± 0.61% . The peak purity of Lawsone was achieved 0.999 r. Relative standard deviation for intraday and inter-day precision was 0.37-0.56% and 0.42-0.55%, respectively. The limit of detection and limit of quantification of the Lawsone were found to be 1.08 μg/m land 3.28 μg/ml, respectively. This result shows that the method was well validated. In the present study, the Lawsone content was found 0.322 ± 0.014% in THHP. This study reveals that the proposed high performance thin layer chromatography method is accurate, fast and cost- effective for routine estimation of Lawsone in polyherbal formulation

Role of Leptin in Obesity Management: Current and Herbal Treatment

Obesity is an excessive accumulation of fat in the body associated with numerous complications such as development of hypertension, type 2 diabetes (T2DM), dyslipidemia, sleep apnea, and respiratory disorders; and ultimately life-threatening cardiovascular disease (CVD), stroke, certain types of cancer and osteoarthritis. In 2016, more than 1.9 billion adults aged 18 years and older were overweight. Of these, over 650 million adults were obese, that is over 39% of men and 40% of women were overweight. Rapid rise in obesity cases in both developed and developing countries and people suffering from it needs rapid and complete cure form it without any side effects. Herbal medicine has been used for the treatment of disease for more than 2000 years, and it has proven efficacy. Many studies have confirmed that herbal medicines are effective in the treatment of obesity. Various plants from different families and several phytochemical constituents are responsible for the anti-obesity activity such as fenugreek cinnamon, cardamom, ginger, etc. Present work mainly cover herbal species having leptin-stimulating potential for weight management, importance of leptin, its mechanism of action, current and herbal treatment for effective weight management
