Background: Some Malaysia and Indonesia people believed that root and seed shell of Archidendron bubalinum can treat diabetes. However, seed shell of Archidendron bubalinum has not yet to be scientifically proven and confirmed their ability to treat diabetes. The study of the potential of this seed shell was also scarcely available. Objective: The recent work was aimed to investigate the phytochemical screening of methanol extracts of seed shells of Archidendron bubalinum and to evaluate their chemical compositions and antidiabetic activities. Material and Methods: The methods of phytochemical screening were including alkaloids, flavonoids, tannins, polyphenols, saponins, and terpenoids. Their chemical compositions were determined by Liquid Chromatography-Mass Spectrometry (LC-MS) and antidiabetic activities were performed by \α-glucosidase inhibitory method. Results: The phytochemical screening showed that methanol extracts of seed shells of Archidendron bubalinum contain flavonoids, tannins, polyphenols, and terpenoids. This extracts exhibited antidiabetic activity with IC50 7.77 \μg/mL. This result was supported by LC-MS analysis which showed the presence of phlorizin and astilbin, in which these compounds had high inhibitory activity against \α-glucosidase or diabetes. Conclusion: LC-MS analysis revealed the presence of polyphenol compounds namely phlorizin and astilbin in which had high \α-glucosidase inhibitory activity, might largely contribute in the antidiabetic activity. Key words: Phytochemical screening, Mass spectrometry

Introduction: To identify the various phyto constituents present in the unexplored plant Rostellularia diffusa (Willd.) by using gas chromatography and mass spectrometry. Methods: The whole plant of Rostellularia diffusa was extracted with ethyl acetate at room temperature for 72 h. The concentrated extract was subjected to GCMS analysis to detect the phyto constituents. Results: Totally 40 compounds were identified and the chromatograph showed 40 peaks with 40 individual compounds. The major constituents were identified in the extract were 16-Hentriacontanone (22.59\%), Hexadecanoic acid (11.23\%), Stigmast-5-en-3-ol (6.78\%), 9-Octadecenoic acid (6.30\%) and many other compounds were identified as low level. This preliminary study gives an idea to isolate the major active constituents present in the plant and also helps to develop potential pharmacologically active compounds

Introduction: Tinospora cordifolia (Willd.) Miers ex Hook F and Thomas commonly called as gudduchi or amrita is a widely used plant in traditional medicinal system of Ayurveda. A UPLC MS/MS Q-tof method for the identification and characterization of berberine in Tinospora cordifolia (Willd.) Miers. ex HooK.F. and Thomas. and to evaluate the anti inflammatory potential of bioactive fraction. Materials and Methods: The presence of berberine in Tinospora cordifolia was determined by HPLC and was subsequently isolated by HPTLC. The anti inflammatory property of the fraction containing berberine was demonstrated to have an inhibitory activity on 5 lipoxygenase, an enzyme involved in inflammatory pathway and its IC50 value was obtained. The binding interactions between berberine and 5-LOX were demonstrated by docking studies. Result: The presence of berberine in Tinospora cordifolia methanolic extract was identified by HPLC and HPTLC analysis and confirmed by UPLC MS/ MS Q-tof. The fraction containing berberine inhibited 5-LOX with an IC50 of 0.041\± 0.0003\μg/mL as compared to that of NDGA (positive control) which showed an IC50 of 2.75 \± 0.05 \μg/mL. Molecular docking of berberine with 5-LOX showed a binding energy of -8.942 \± 0.039665 kcal/mol and Ki of 273.16 \± 3.026 nM as compared to the NDGA which has a binding energy of -7.186 \± 0.170503 kcal/mol and Ki 5.604\± 1.618 \μM. Conclusion: Tinospora cordifolia can be used as a source of berberine and possible anti inflammatory activity of Tinospora cordifolia may be attributed to the presence of berberine.
