Combination of kapok leaf extract (Ceiba pertandra G.) and turmeric extract (Curcuma domestica Va.) was carried out to determine the potential of extracts in treating cancer with BSLT and murine cells P388. Cancer is a disease that is very feared because it’s difficult to cure, and even rarely causes death. The sample was extracted with methanol, the extract was mixed so that the mixture extract from the two samples was obtained. The results showed that in the BSLT test the mixed extract had a bioactivity against shrimp larvae with an LC50 value of 142.946 ppm. While in Leukemia P388 cell testing showed that the combination of mixed extracts had a cytotoxic effect on Leukemia P388 cancer cells with inhibitory concentration values of 54.34 ppm. This shows that the kapok leaf extract (Ceiba pentandra G.) and combination of turmeric extract (Curcuma domestica Va.) has potential and can be developed as an anticancer agent because it has an IC50 value that can inhibit murine P388 cell growth and LC50 value which can kill shrimp larvae Artemia salina L.

Abstract : This study aims to determine the antidiabetic activity and toxicity of the acetone extract of Tristaniopsis merguensis Griff leaf. The antidiabetic test was the α-glucosidase inhibition method, while the toxicity test used the Brine Shrimp Lethality Test (BSLT) method. The acetone extract possessed antidiabetic activity with an IC50 value of 8.83 ± 0.31 (μg/mL). This value is not much different from the positive control of quercetin which has an IC50 value of 6.04 ± 0.14 (μg/mL). The characteristics of the FT-IR spectrum of acetone extract showed that Tristaniopsis merguensis leaf has the groups Ar-OH (phenolic), -OH (hydroxyl), C=O (ketone) and C=C (aromatic). Based on the toxicity test, the Tristaniopsis merguensis leaf acetone extract has an LC50 value of 959.25 ppm which means that the acetone extract is toxic. Therefore, the acetone extract of Tristaniopsis merguensis might be the potential agent of antidiabetic.Abstrak : Penelitian ini bertujuan untuk mengetahui aktivitas antidiabetes dan toksisitas dari ekstrak aseton daun Tristaniopsis merguensis Griff. Uji aktivitas antidiabetes ditentukan berdasarkan metode inhibisi enzim α-glucosidase, sedangkan toksisitas ditentukan berdasarkan metode Brine Shrimp Lethality Test (BSLT). Ekstrak aseton memiliki aktivitas antidiabetes dengan nilai IC50 8,83 ± 0,31 (μg/mL). Nilai ini tidak jauh berbeda dengan kontrol positif quersetin yang memiliki nilai IC50 6,04 ± 0,14 (μg/mL). Karakteristik spektrum FT-IR ekstrak aseton menunjukkan bahwa daun Tristaniopsis merguensis memiliki gugus fungsi Ar-OH (fenolik), -OH (hidroksil), C=O (keton) dan C=C (aromatik). Berdasarkan uji toksisitas, ekstrak aseton daun Tristaniopsis merguensis memiliki nilai LC50 sebesar 959,25 ppm yang berarti bahwa ekstrak aseton bersifat toksik. Oleh karena itu, ekstrak aseton dari Tristaniopsis merguensis berpotensi untuk dijadikan agen antidiabetes.

Background: In developed countries cancer is the second leading cause of death after cardiovascular disease. Cancer prevention can be done with synthetic or traditional medicine. However, synthetic treatments often cause side effects and of course require high costs. Java Cardamom (Amomum compactum Soland. Ex Maton) is a plant that contains antioxidants. Antioxidants can inhibit oxidation reactions by binding to free radicals and molecules that are very reactive so that cell damage can be prevented. Cardamom contains flavonoids which can induce cell death programs as well as tannins as free radical scavengers.Objectives: This study aims to determine the LC50 value of Java cardamom (Amomum compactum Soland. Ex Maton) on Artemia salina Leach.Methods: This study was an experimental study using a completely randomized design (CRD) using 180 artemia larvae which were divided into 6 treatment groups. Each group included 10 artemia larvae with varying concentrations of 500 ppm, 250 ppm, 100 ppm, 50 ppm, 10 ppm and 0 ppm (not given extract). Three repetitions were performed for each concentration.Results: The results showed from the observations obtained the LC50 value of Java cardamom extract is 26.60 ppm. So that the Java cardamom extract (Amomum compactum Soland. Ex Maton) has the potential as an anticancer (cytotoxic).Conclusion: Java cardamom extract (Amomum compactum Soland. Ex Maton) is active and can be developed as an anticancer compound.

Background: Diabetes mellitus is the most occurring non-communicable disease resulting in a high blood glucose level. There has been an immense interest in the development of alternative medicines for diabetes treatment, specifically screening functional foods for phytochemicals with the capability of delaying or preventing glucose absorption through digestive enzymes (e.g. α-amylase) inhibition. So, the development of α-amylase inhibitors derived from natural food products is an alternative way to prevent diabetes mellitus Objective: In this study, organic solvent extracts of the Arachis hypogaea (Peanut) and Cinnamomum tamala (Indian bay leaf /Tejpata) were used to investigate their potential α-amylase inhibition and cytotoxic activities through α-amylase inhibition assay and brine shrimp lethality bioassay respectively Method: The α-amylase inhibition assay was performed using the 3,5-dinitrosalicylic acid method for different concentrations of plant extracts. The optical density (OD) of the solutions were measured to determine the inhibition activity at 540 nm using a spectrophotometer. The cytotoxicity of the plant extracts was measured using brine shrimp (Artemia salina) lethality bioassay Results: Among the different organic solvent extracts, peanut seed ethanol extract showed the highest α-amylase inhibition activity (67.68±8.67%) at 1.25 μg/mL concentration with an IC50 value of 0.61 μg/mL which is very close to standard α-amylase inhibitor Acarbose (72.34±4.23%) with an IC50 value of 0.32 μg/mL while acetone extract of Indian bay leaf exhibited the lowest inhibition activity (47.75±1.63%) with an IC50 value of 1.42 μg/mL at the same concentration. Besides, the maximum cytotoxic activity was found in acetone extract of peanut shell with an LC50 value of 57.87 μg/mL whereas ethanol extract of peanut seed showed the lowest cytotoxicity with an LC50 value of 413.90 μg/mL Conclusion: The result of the present work clearly indicates the potentiality of peanut seed ethanol extract to be used in the management of hyperglycemia as it significantly inhibits α-amylase activity while showing less cytotoxic activities

Antiviral treatments inhibiting Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) replication may represent a strategy complementary to vaccination to fight the ongoing Coronavirus disease 19 (COVID-19) pandemic. Molecules or extracts inhibiting the SARS-CoV-2 chymotripsin-like protease (3CLPro) could contribute to reducing or suppressing SARS-CoV-2 replication. Using a targeted approach, we identified 17 plant products that are included in current and traditional cuisines as promising inhibitors of SARS-CoV-2 3CLPro activity. Methanolic extracts were evaluated in vitro for inhibition of SARS-CoV-2 3CLPro activity using a quenched fluorescence resonance energy transfer (FRET) assay. Extracts from turmeric (Curcuma longa) rhizomes, mustard (Brassica nigra) seeds, and wall rocket (Diplotaxis erucoides subsp. erucoides) at 500 µg mL−1 displayed significant inhibition of the 3CLPro activity, resulting in residual protease activities of 0.0%, 9.4%, and 14.9%, respectively. Using different extract concentrations, an IC50 value of 15.74 µg mL−1 was calculated for turmeric extract. Commercial curcumin inhibited the 3CLPro activity, but did not fully account for the inhibitory effect of turmeric rhizomes extracts, suggesting that other components of the turmeric extract must also play a main role in inhibiting the 3CLPro activity. Sinigrin, a major glucosinolate present in mustard seeds and wall rocket, did not have relevant 3CLPro inhibitory activity; however, its hydrolysis product allyl isothiocyanate had an IC50 value of 41.43 µg mL−1. The current study identifies plant extracts and molecules that can be of interest in the search for treatments against COVID-19, acting as a basis for future chemical, in vivo, and clinical trials.

According to the literature survey most of the studies done on Adarak (Zingiber officinale rhizome) were performed on alcoholic extracts or isolated entities of ginger but no profound work has been done on the traditionally prepared or commonly consumed way of ginger. So, in this current study, fresh ginger rhizomes were traditionally pounded to make Adarak juice. The different concentration (0.05%, 0.5%, 1%, 2.5%, 5%, 10%) were taken as sample to perform onion root tip inhibition assay and brine shrimp lethality bioassay. It showed antimitotic inhibition in the range of 0.05-10% concentration with an IC50 value of 0.37 % on number of rootlets was 0.08 % on length of rootlets. The traditionally prepared Adarak juice showed cytotoxicity in the range of 0.05-2.5% concentration with LC50 value of 1.59%. The traditionally prepared Adarak juice possesses cytotoxic and antimitotic activity.

Celastrus hindsii Benth et Hook. is known as a herbal medicine for the treatment of cancer. In this study we evaluated the cytotoxic and antioxidant effects of Celastrus hindsii Benth et Hook. leaf extract. Samples of Celastrus hindsii were extracted with 90 % ethanol and subsequently fractionated with n-hexane, ethyl acetate (EtOAc) and n-butanol (n-BuOH) solvents. To evaluate the cytotoxic effect, we performed MTT (3- (4,5 dimethylthiazol-2 - yl) - 2,5 - diphenyltetrazolium) assay on the three cell lines human liver Hep G2 (HB - 8065TM), lung LU-1 (HTB - 57TM), breast MCF-7 (HTB - 22TM).  The antioxidant effect was evaluated by screening DPPH (2,2-diphenyl-1-picryhydrazyl) free radical assay. The results showed that the EtOAc fraction had the strongest cytoxicity effects on liver cancer cells and lung cancer cells with an IC50 value of 33,7 ± 1,5 mg/mL and 13,0 ± 0,5 mg/mL. The BuOH fraction showed a weaker effect on lung cancer cells with IC50 value of 64,0 ± 2,2 mg/mL. The antioxidant results indicated that the EtOAc fraction had the best antioxidant effect with IC50  value of 46,9 ± 2,5 µg/mL. The EtOH total extract also has strong antioxidant activity with IC50 value of 48,5 ± 2,3 µg/mL. Our study showed that Celastrus hindsii leaf extract has the strong cytotoxicity and antioxidant activities. Keywords Celastrus hindsii Benth et Hook., cytotoxicity, MTT, antioxidant, DPPH.

Disease cancer caused by abnormal growth of tissue where there has been an error, fast and out of control. Judging from the fact of gender, more than 270,000 women die every year caused by cervical cancer. To inhibit the growth of cancer cells, a compound is needed that causes the cell cycle to stop so that the ability of cell proliferation decreases. Alkaloid compounds can inhibit proliferation through oxidative inhibition processes that can cause cancer. Mangrove plants have potential as anticancer, antimicrobial, and antioxidant. The content of chemical compounds found in mangroves are flavonoids, steroids, alkaloids, phenolites, saponins and tannins. These compounds show high antioxidant activity and are shown to have a real relationship with the properties of the material's bioactivity against cancer cells. One of the mangrove species is Rhizophora apiculata. The purpose of this study was to determine the IC50 value produced by Rhizophora apiculata mangrove leaf extract on HeLa cell viability and to see the effect of Rhizophora apiculata mangrove leaf extract dosage on HeLa cell viability. The method used in this research is the experimental method. The research parameters included yield, proximate test, phytochemical test, toxicity test, total phenol test, cytotoxicity test and LC-MS test. The experimental design used was a simple and complex completely randomized design (CRD) with the Tukey test.The results of this study showed that the highest yield was in the ethanol extract of 5.91%, while the n-hexane and ethyl acetate extracts respectively had yields of 1.18% and 1.31%. The results of the proximate test on the water content of leaves and powder were 64.53% and 13.86%, respectively, the results of the ash content in the leaves and powder of Rhizophora apiculata were 3.94% and 8.41%, respectively. while the water content in the extract obtained the highest yield in the ethanol extract of 21.42%, while the n-hexane extract and ethyl acetate extract were 11.08% and 15.42%, respectively. For phytochemical results, it was found that n-hexane extract only contained alkaloids, flavonoids and steroids. Ethyl acetate extract contains steroid compounds. Meanwhile, the ethanol extract contains the most bioactive compounds, namely saponins, flavonoids, tannins and triterpenoids. The toxicity test using the Brine Shrimp Lethality Test (BSLT) method resulted in the lowest IC50 of ethanol extract at 49.45 ppm while the n-hexane and ethyl acetate extracts were 251.63 ppm and 920.45 ppm respectively. In the total phenol test, the n-hexane extract was 66.79 mg GAE / 100 gr, 222.97 mg GAE / 100 gr ethyl acetate extract and 929.04 mg GAE / 100 gr ethanol extract. HeLa cell cytotoxicity testing using the MTT method (3- (4,5-dimethiltiazol-2-yl) -2,5-dipheniltetra zolium bromide) assay resulted in the highest cell viability value at a dose of 125 ppm of 46.97%. As for the doses of 250 ppm, 500 ppm 1000 ppm, and 2000 ppm resulted in a percentage of viability of 42.95% 37.70% 35.82% and 32.12%, respectively. The IC50 value of Rhizophora apiculata leaf extract was 64.42 ppm. This value indicates that the Rhizophora apiculata extract is toxic to HeLa cells.
