Introduction: Mango ginger (Curcuma mangga) is one of Indonesia{\textquoteright}s medicinal plants widely used in most communities as a lust booster and for detoxifying purposes. Therefore, the purpose of this study is to synthesize chitosan-tripolyphosphate nanoparticles from mango ginger extract, determine their chemical contents, the nano chitosan characteristics, and its antioxidant activity. Methods: In this study, we macerated mango ginger using 70\% ethanol solvent, then performed phytochemical test and formulation of chitosan nanoparticles of mango ginger extract. The group of secondary metabolites that showed positive results with the reagent test was further identified through TLC. Results: The results showed that the extract contained flavonoids and triterpenoids. Also, characterization of chitosan nanoparticles from the extract was conducted with FTIR test, PSA, XRD, and SEM. Based on the results, the nano chitosan particle size was 993 nm and examination with FTIR showed the presence of N-H and P=O groups, indicating ammonium ion interaction from chitosan with the polyanion from TPP and Mango ginger. Additionally, the XRD results showed that the crystals formed were in an amorphous form, which was supported by particle morphology images from SEM. Furthermore, the nanoparticles showed very strong antioxidant activity based on the reaction with DPPH. Conclusion: Based on these results, the phytochemical identification of mango ginger extract showed positive results in flavonoid and triterpenoid compounds. In addition, based on the characterization of the nanoparticles, the mango ginger extract showed positive results, illustrating that the nano chitosan synthesis was successful. Furthermore, the nano chitosan has a very strong antioxidant activity with an IC50 value of 18.08 μg/mL.

Introduction: Apart from the medical advancement of chemotherapy, various plants were known as beneficial for cancer therapy because they can kill cancer cells selectively without damaging the normal cells. Here, we showed that nanoparticles formulated from chloroform fraction of soursop (Annona muricata L.) leaves and ethyl acetate fraction of sappan wood (Caesalpinia sappan L.) have anti-proliferative and cytotoxic effects on HeLa cervical cancer cells. Methods: The cytotoxic effect was evaluated using a single dose of each nanoparticle and a combined dose to obtain a synergistic effect. The mechanism of induced cell death via apoptosis or necrosis pathway was evaluated using flow cytometry by incorporating Annexin V and propidium iodide. Results: Synthesis of nanoparticles from the extract of soursop leaves (nano-SL) and extract of sappan wood (nano-SW) yielded particle sizes ranging from 248 to 317 nm. Nano-SL and nano-SW decreased the viability of HeLa cervical cancer cells in a dose-dependent manner with IC50 values of 63,32 μg/ml dan 40,88 μg/ml, respectively. The combined dose of 1/8 IC50 from both nanoparticles showed a strong synergistic effect, as shown by the combination index value of 0.13 based on the same mode of action and different modes of action. In HeLa cells treated with a combined dose of nanoparticles, the total apoptotic cells increased two times greater than that in control cells. Conclusion: Nano-SL and nano-SW induce apoptosis and necrosis in HeLa cells. Combined-dose of both nanoparticles produced a synergistic effect that could reduce the amount of the required individual dose while increasing the total effect.

Couroupita guianensis is commonly known as cannonball tree, belonging to the family Lecythidaceae. This tree has enormous medicinal values since most of its parts are used as medicines traditionally. In this work, two major aspects were studied. Firstly, the phytochemical screening and biological activities of various extracts of leaf, flower and fruit are prepared and studied. Secondly, silver nanoparticles were synthesized from these parts, characterized instrumentally and checked for its antibacterial activity. This study reveals that except the aqueous extracts, all other extracts have good antioxidant and antibacterial activity hence stating the presence of bioactive compounds. Flower mediated nanoparticles showed better results than others which may be due to the presence of certain phytochemical compounds responsible for the reduction and capping of silver nanoparticles. These results showed the potential of Couroupita guianensis and further investigation to isolate such pharmacologically active compounds that can be used in the production of novel drugs for various diseases would be promising.
