Background: The main active compound of bitter melon (Momordica charantia Linn.) fruit is charantin, which is believed to have important role on antihyperglycemic effect. However, charantin compound has a large molecular weight and is easily hydrolysed when given orally. Therefore, a colloidal drug delivery system, such as solid lipid nanoparticles (SLN), is required to provide a suitable and effective delivery of charantin, which is contained in a bitter melon fraction (BMF). Objective: This study aimed to prepare and evaluate SLN containing BMF with an appropriate characteristic for transdermal delivery. Methods: Bitter melon fruits were extracted with ionic liquid of [BMIM]BF4 using ultrasound-assisted extraction (UAE) and fractionated with dichloromethane. Four formulas of BMF loaded SLN were prepared with various ratio of BMF to surfactant and various ratio of lipids using high-shear homogenization followed by ultrasonication method. The obtained SLN were characterized, including morphology, particle size distribution, zeta potential, and entrapment efficiency. Furthermore, the stability study of BMF-loaded SLN was also conducted. Results: The result showed that BMF was a dry powder and brownish fraction with a specific smell. The BMF loaded SLN showed a spherical shape with the SLN F1 formula as a selected formula. The SLN F1 showed a particle size (Z-average) of 98.3{\textpm}1.98 nm, polydispersity index of 0.26{\textpm}0.01, zeta potential of -39.53{\textpm}0.15 mV, and entrapment efficiency of 82.96{\textpm}1.42 \%. According to the stability study, it revealed that the BMF loaded SLN F1 had an acceptable stability, which the charantin content in the SLN was 96.52\% after 3 months storage at 25{\textdegree}C {\textpm} 2{\textdegree}C. Conclusion: The BMF loaded SLN F1 with 1:12 ratio of BMF to surfactant and 1:2 ratio of capric caprylic triglyceride to glyceryl monostearate was selected as the best formula with the appropriate characteristics for transdermal delivery.

Momordica charantia L. (bitter melon) is a plant belonging to the Cucurbitaceae family and is widely distributed in tropical and subtropical areas around the world, mainly in Asia, India, China and Brazil, where it is traditionally used as a medicinal plant, and the fruits of some varieties of M. charantia are consumed as food. Studies have determined that this plant contains a great diversity of bioactive compounds with therapeutic potential like charantin, α-momorcharin and MAP30, and highlighting its properties as antidiabetic, antiulcer, antioxidant, antimicrobial, anthelmintic, antihyperglycemic and anticancer. Review shows the complete botanical description of the plant (fruits, leaves, stem, etc.), the bioactive chemical compounds reported in the plant species, the antimicrobial activity of the extracts or fractions of M. charantia, emphasizing the antibacterial and antifungal activities, with respective values of MIC (Minimum Inhibitory Concentration) reported according to the methodology used in each study. The review seeks to update the phytochemical and pharmacological knowledge of M. charantia, which would be useful for researchers in their search for new chemical compounds of the plant, studies of its safety and efficacy, as well as the evaluation of its possible synergistic action in combination with other antimicrobials, in order to find new therapeutic alternatives against bacterial resistance.

Objective: Bitter melon fruit, which is containing charantin, has poor penetration through the skin. This problem can be solved with the lipid vesicle called ethosomes that offers better skin penetration. This study was aimed to develop ethosomes for improving skin penetration ability of charantin. Methods: Bitter melon was extracted with ethanol 80\% and fractionated with dichloromethane. Ethosomes were formulated with a various concentration equal to 2\% (F1), 3\% (F2) and 4\% (F3) of bitter melon fruits fraction (BMFF) and prepared using thin layer hydration method. The obtained ethosomes were characterized, then the penetration study was conducted using Franz diffusion cells. Results: The results showed that the BMFF was a dry, brown-greenish fraction and gave a positive test for a steroid. The entrapment efficiency of ethosomes F1, F2 and F3 was 91.50 {\textpm} 0.40\%, 92.62 {\textpm} 0.26\% and 83.85 {\textpm} 1.10\%, respectively. Moreover, the particle size (Dv90) of ethosomes F1, F2 and F3 was 1083.33 {\textpm} 15.27 nm, 1736.67 {\textpm} 11.55 nm and 1976.67 {\textpm} 5.77 nm, respectively. Ethosomes F1, F2 and F3 resulted polydispersity index of 0.42 {\textpm} 0.02, 0.35 {\textpm} 0.05 and 0.50 {\textpm} 0.11, as well as zeta potential of -54.33 {\textpm} 0.75, -57.50 {\textpm} 0.44 and -50.60 {\textpm} 0.98, respectively. Besides, all ethosomes had a spherical shape. The research revealed that ethosome F2 was the optimal ethosome among another formulas. Cumulative percentage of penetrated stigmasterol glycoside for ethosome F2 was 18.25 {\textpm} 0.08\%, while the control solution did not penetrate within 20 h. Conclusion: This research demonstrated that the ethosome could increase the skin penetration of stigmasterol glycoside, which is charantin content, from the fraction of bitter melon fruit.
