The whole plant of bhringaraj (Eclipta alba) was dried and pulverized. The phytoconstituents of the pulverized plant material were extracted separately with two different solvents namely petroleum ether (hot percolation) and methanol (cold maceration) to carry out a comparative extraction efficiency of the above two solvents. β-sitosterol reported to have antiandrogenic, anticancer, antiinflammatory, antiprostatitic, antitumor, etc. activity, was selected as the active biomarker for quantification of the aforementioned plant material.HPTLC was carried out for quantification of the biomarker and obtained data was compared with HPLC data. Petroleum ether was found to be an effective extracting solvent for β sitosterol from E. alba as compared to methanol. The percentage content of β-sitosterol in E. alba methanolic and petroleum ether extract was found to be 0.10% and 4.65% w/w respectively by HPTLC whereas the percentage content of β-sitosterol in Eclipta alba petroleum ether extract was found to be 4.67 % w/w by HPLC. AAS data revealed the presence of the metals (ppm ± SEM) are within safety limits, copper (1.151 ± 0.031), chromium (0.528 ± 0.012), cadmium (0.021 ± 0.035), lead (0.860 ± 0.009), arsenic (0.081 ± 0.007), mercury (0.036 ± 0.010).

The present work has been undertaken with the aim to formulate hair growth gel formulation containing extracts of Hibiscus rosa sinensis flower 1%, Eclipta alba whole plant 1% and Solanum nigrum plant berries 0.5% which are preferably used in case of Alopecia, i.e., baldness pattern as an effective herbal therapy showing 5 α-reductase inhibitory activity. The formulated gel was evaluated for parameters such as pH which was found to be 6.68, viscosity 4731 cps, spreadability 11.05 (g-cm/sec) whereas consistent homogeneity was found with no skin irritation. Simultaneous quantification of bioactive markers was done by HPTLC. Quercetin, β-sitosterol and linoleic acid were selected as bioactive markers for quantification of Hibiscus rosa sinensis flower, Eclipta alba whole plant and Solanum nigrum plant berries extract respectively in the formulation. The aforementioned markers have 5 α-reductase inhibitory activity. β-sitosterol, quercetin and linoleic acid was found to be 0.1377, 0.120 and 0.379% w/w respectively in the formulated gel.

Objective: The present study was aimed to develop topical gel containing β-sitosterol using carbopol 940 as a gelling agent and to investigate 5 alpha reductase (5α-reductase) inhibitory activity of suitable gel formulation and compare it with a commercial product used topically for alopecia. Methods: Three different batches of β-sitosterol hair gel formulation were manufactured and evaluated. Additionally, the 5α-reductase inhibitory activity of the prepared formulation, finasteride as a positive control, was evaluated and compared to the commercial herbal formulation used. Results: According to the analytical findings of three different batches, the gel formulation is good in appearance, homogeneous, and easily spreadable. Based on findings from HPLC and HPTLC, the amount of β-sitosterol in those formulations complies with the label claim. By checking different critical parameters of those batches, we established the manufacturing process method validation and the process reproducibility. In vitro results showed the good 5α-reductase inhibitory potential of prepared gel formulation and then commercial product. The IC50 value of the prepared formulation was 118.960±0.634 (µg/ml) and standard beta-sitosterol 88.854±0.70 (µg/ml), whereas Finasteride (positive control) 224.372±3.103 (ng/ml). Conclusion: Thus, β-sitosterol formulation utilises a straightforward, low-cost production, less time-consuming process with minimal facility and equipment requirements. The formulation may be a promising candidate for future investigation into their antiandrogenic activities.
