Abstract

Background: Hypertension is defined as a medical condition where blood pressure rises above 140/90 mmHg. Black garlic is recognized as a natural remedy that may help lower high blood pressure, primarily due to its abundant antioxidant properties, which are believed to inhibit the function of the angiotensin-converting enzyme (ACE) that is essential for regulating blood pressure. Objective: This study aimed to identify the chemical composition of black garlic using GC-MS and assess its antihypertensive effects in rat models. Methods: This study characterized the chemical composition of black garlic using GC-MS (Agilent 7890A) and evaluated its antihypertensive effects in rats. Hypertension was induced by oral administration of NaCl at a dose of 3.75 g/20 g body weight (BW) from day 0 to day 14. Blood pressure measurements were taken on days 0, 14, and 21. Black garlic extract was administered at three dose levels 4.2 mg/20 g BW, 8.4 mg/20 g BW, and 12.4 mg/20 g BW to evaluate dose dependent antihypertensive responses. Statistical analysis included the Kolmogorov-Smirnov test for normality, homogeneity testing, One-Way ANOVA Results: The GC-MS analysis identified 9-octadecenoic acid as the dominant compound in black garlic, accounting for 34.53% of its total composition. The antihypertensive activity test showed that administering black garlic at a dose of 12.4 mg/20 g BW significantly lowered systolic, diastolic, and mean arterial blood pressure while enhancing nitric oxide levels in hypertensive rats. Conclusion: Black garlic has the potential as an effective herbal treatment to lower blood pressure.

Abstract

The first-line chemotherapy drug for breast cancer is cisplatin. However, it shows a high incidence of resistance. Therefore, Hibiscus Sabdariffa L (HS), containing strong anticancer compounds, was developed using a self-nano-emulsifying drug delivery system (SNEDDS), potentially as cisplatin co-chemotherapy. This study aimed to develop the HS SNEDDS providing anticancer activity against T47D breast cancer cells. The methods consist of the development of HS SNEDDS (F1-F7) with various surfactant and co-surfactant concentrations, followed by characterization of HS SNEDDS. The selected formulation was evaluated regarding the cytotoxicity on T47D cells and selectivity on Vero cells. The results showed that F7, as a selected formulation, indicated a transmittance, globule size, PI, zeta potential, and emulsification time of 97.80%, 15.68 ± 0.19 nm, 0.12 ± 0.01, -8.05 ± 1.88 mV, and 24.76 ± 0.29 seconds, respectively. Furthermore, according to the data of toxicity and selectivity studies, HS SNEDDS was proven to enhance the toxic properties of HS extract on T47D cells and be safe on normal cells. In conclusion, HS SNEDDS providing the required characteristics could be obtained, and potentially be used as a co-chemotherapy of cisplatin, showing the cytotoxic effect on T47D breast cancer cells.
