The current research was designed to examine the antidiabetic and anti-microbial activities in the extracts of methanol, ethyl acetate and hexane from Flesh of Matoa (Pometia pinnata J. R. Forst. & G. Forst) to find out the best solvent to produce antidiabetic and anti-microbial active compounds.  In the phytochemical screening, hexane extracted alkaloids and terpenoids, while ethyl acetate extracted saponin and methanol extracted tannin, phenol and terpenoids. In the antidiabetic activity by a-glucosidase inhibition methods, ethyl acetate showed the highest percentage of inhibition and the smallest value of IC50, followed by hexane and methanol compared to the Quercetin as the control group. The maximum percentage inhibition was 36.74 ± 0.07 for 100 µg/mL of concentration. The minimum value of IC50 was observed at 159.74 ± 0.65 µg/ml compared to the control group 6.04 ± 0.14 µg/ml. The smaller the IC50 value, the stronger the antidiabetic activity. Anti-microbial inhibition activities assessed using anti-microbial diffusion test method. The hexane and ethyl acetate extracts provide an inhibition of fungi and bacteria compared to Ketoconazole and Amoxicillin as the standard. The maximum fungi inhibition zone was observed at 4 mm for A. flavus and 9 mm for A. niger by Hexane extracts compared to the standard 14 and 24 mm. The maximum bacteria inhibition zone was observed at 7 mm for B. cereus by both of hexane and ethyl acetate extracts compared to the standard 5 mm. Compared to the anti-microbe inhibitory power categories, hexane and ethyl acetate was on the range of weak and moderate. The methanol extract could not inhibit all types of microbe. This study concluded that various extract of flesh of Matoa showed antidiabetic and anti-microbial activities at different value with varying potencies. The ethyl acetate extract was found to be more potent among all, followed by hexane and methanol. HIGHLIGHTS Phytochemical screening of Flesh of Matoa (Pometia pinnata R. Forst. & G.

Syzygium aqueum, consisting of various fruit colors, is one of the plants that have been used as traditional medicine. This study aims to evaluate and compare phytochemical, antioxidant, and cytotoxic activities and total phenolic content of leaves and stem bark extracts of S. aqueum with pink and red fruits, in order to identify the best extract that can be used as a natural antioxidant. Phytochemical constituents were evaluated qualitatively using chemicals, while cytotoxic activities were identified using the brine shrimp lethality test. Total phenolic content was determined via the Folin–Ciocalteu method. Leaves and stem bark of S. aqueum contained flavonoids, phenolics, and triterpenoids, but the stem bark also contained saponins and alkaloids. Methanol and ethyl acetate extracts of leaves and stem bark were categorized as very powerful antioxidants to DPPH (IC50 9.71–38.69 μg/mL) and hydrogen peroxide (IC50 16.44–44.02 μg/mL), while hexane extracts were inactive. Methanol, ethyl acetate, and hexane extracts of leaves and stem bark were categorized as moderately cytotoxic to A. salina larvae (LC50 104.04–440.65 μg/mL). Comparing leaves and stem barks, antioxidant and cytotoxic activities of stem bark extracts were higher than those of leaves extracts. Total phenolic content of leaves extracts was higher than that of stem bark extracts where the order of total phenolic content progressed from methanol extracts > ethyl acetate extracts > hexane extracts. Therefore, the stem bark of S. aqueum was identified as the better source of natural antioxidant compared with the leaves.

The A. indica and C. hirsutus plant was collected from Kadaparajupalle at Dornala mandal, Prakasam district, Andhra Pradesh, India. Leaf, stem bark and root crude extracts prepared in Soxhlet apparatus with chloroform, ethyl acetate and methanol solvents. The preliminary phytochemical screening of these extracts was conducted by following the standard methods. These extracts were tested for in vitro antimalarial activity against 3D7 and K1 strains of Plasmodium falciparum by standard laboratory protocol. In vitro cytotoxicity of the extracts was also tested by following standard laboratory method. The phytochemical screening has revealed the presence of alkaloids, saponins, terpenoids & steroids, tannins, anthocyanidins, phenolic compounds, coumarins, quinones, resins and glycosides. Amongst all the extracts screened for antimalarial activity, the leaf chloroform and ethyl acetate extracts of A. indica shown IC50 values of 3.34 µg/mL and 3.71 µg/mL respectively against 3D7 strain; the leaf chloroform and ethyl acetate extracts of A. indica shown IC50 values of 1.47 µg/mL and 2.32 µg/mL respectively against K1 strain; the root chloroform and methanol extracts of C. hirsutus shown IC50 values of <0.78 µg/mL and 3.714 µg/mL respectively against 3D7 strain; the root chloroform and methanol extracts of C. hirsutus shown IC50 values of <0.78 µg/mL and 2.10 µg/mL respectively against K1 strain. Thus, the above extracts have shown very active antimalarial activity against 3D7 and K1 strains. And all the extracts were non-toxic showing CC50 values of >20 µg/mL against Vero cell line. The presence of high alkaloids, flavonoids and terpenoids of the plant extracts suggest their antioxidant potential and justifies their therapeutic action which could be used for the drug formulation. The chloroform root extract of C. hirsutus has shown excellent antimalarial activity which can be used for the development of new antimalarial drug policies.
