Propolis is one of the natural products produced by kelulut bees and is still not widely used. The type of stingless bee that is the prima donna in the community is Heterotrigona itama. This study aims to determine the phytochemical content of the n-hexane fraction of Heterotrigona itama bee propolis collected from Kutai Kartanegara, East Kalimantan. The n-hexane fraction was obtained from the methanol extract of H. itama propolis by the liquid-liquid partition method. After obtaining the n-hexane fraction, the research continued with a qualitative phytochemical test to identify the compound and determine total phenolic. Antibacterial activity was determined by the agar well diffusion method with a serial concentration in Escherichia coli bacteria. Qualitative phytochemical analysis in the form of color changes showed that the n-hexane fraction of H. itama propolis contained flavonoids, alkaloids, saponins, and tannins. Based on the results, the total phenolic content of the n-hexane fraction sample was 490 mgGAE/100 g. It caused the n-hexane fraction to have lower phenolic content than the methanol extract (792 mg GAE100 g). Furthermore, this result indicated that the non-polar fraction was not substantial enough to extracted phenolic compounds. It correlated to the antibacterial activity of the n-hexane fraction, which was very weak (2  mm ± 1.5) at  200µg/mL concentration.

Aim: This study investigated the phytochemical constituents and in vitro antioxidant properties of methanol and aqueous leaf extracts of Geophila obvallata using standard methods. Materials and Methods: The in vitro antioxidant assays carried out were 1, 1‐diphenyl‐2‐picrylhydrazyl (DPPH) radical scavenging ability, Nitric oxide (NO•) radical scavenging activity assay, 2, 2'-azino-bis (3-ethylbenzthiazoline-6-sulphonic acid) (ABTS•+) radical cation scavenging assay, ferric reducing properties and hydroxyl radical scavenging assays. Results: Phytochemical analysis revealed the presence of alkaloids, flavonoids, phenolic compounds, steroids, saponins, terpernoids and cardiac glycosides in both extracts. Relative to the aqueous extract, the methanol extract contained a higher amount of the secondary metabolites. However, both extracts exhibited appreciable and dose-dependent capacities for quenching DPPH, ABTS•+ and NO• free radicals, and potent ferric reducing ability to levels comparable to those of ascorbic acid. The crude methanol extract showed significantly increased (P<0.05) antioxidant activity than the aqueous extract. Conclusion: It was concluded that the extract possesses strong antioxidant properties due to its content of phytochemicals, and provides scientific basis for its ethno medicinal applications.

Comparative study of plant extracts crude and aqueous, methanolic and ethanolic with antibiotics, provide evidence that calotropis procera extracts has the similar antibacterial activity as these antibiotics against test pathogens i.e. Salmonella typhi and E.coli. The analysis of antimicrobial activity of aqueous, methanolic and ethanolic extract of leaves and flower of Calotropis procera was carried out in disc method and also determined MIC value at 600nm through optical density using spectrophotometer. The zone of inhibition produced by extracts was examined and compares it with zone produced by antibiotics. The effect exhibited by ethanolic extract of leaves and flower was significantly greater than the aqueous and methanolic extract of leaves and flower. Crude extracts i.e. latex, leaves, fruit and flower crude extracts. Among them, flower crude extracts shows similar zone of inhibition to test anitibiotics.while in MIC value, we made different concentration of extracts and antibiotics.i.e for crude we made 25%, 50%.75% and 100% concentration of crude juice and for the aqueous, methanolic and ethanolic we made 0.5mg/mL,1mg/mL,2mg/mL,3mg/mL,4mg/mL, 5mg/mL and 6mg/mL in Dimethyl salfoxide, and same antibiotics concentration. Aqueous leaves extracts show MIC at 0.5mg/ml against E.coli while against Salmonella it shows MIC at 1mg/ml... We also determine phytochemical analysis for presences of different compounds in crude extracts. The obtained results provide a support for the use of Calotropis procera, in traditional medicine and suggest its further advance investigation.
