Background: Type 2 Diabetes mellitus is a chronic metabolic disorder which worsens by increased oxidative stress resulting in other diabetes associated complications. Tinospora cordifolia (TC) and Azadirachta indica (AI) are traditional medicinal plants that has been used for diabetes since ancient times, but their combined potential as a formulation has not been evaluated for the management of diabetes. Objectives: This study aimed to profile the phytochemical composition of 70\% hydroethanolic extracts of TC and AI, assess their antioxidant and antidiabetic activity individually and in combination, and further substantiate their efficacy through in-silico molecular docking and ADMET evaluation of their key bioactive compounds, berberine and nimbolide. Methods: Hydroethanolic extracts of TC and AI were subjected to preliminary phytochemical screening, quantification of primary and secondary metabolites, and HPTLC profiling. Five combinations of TC:AI (1:1, 1:2, 2:1, 1:3, 3:1) were prepared and evaluated for antioxidant activity using DPPH, ABTS, and FRAP assays, and for antidiabetic potential using α-amylase, α-glucosidase, and PTP1B inhibition assays. IC$_{5}$$_{0}$ values were calculated. In-silico studies were performed for berberine and nimbolide using AutoDock 4.2.6 against PPARγ, GLUT4, and IRS1. Drug-likeness and ADMET properties were predicted using SwissADME and pkCSM. Results: Phytochemical profiling confirmed the presence of alkaloids, polyphenols, flavonoids, and tannins. TC demonstrated stronger inherent antioxidant and antidiabetic activity than AI. Among combinations, 1:1 and 3:1 formulations showed the highest potency with IC$_{5}$$_{0}$ values comparable to standards. Molecular docking revealed strong binding affinities of berberine and nimbolide toward PPARγ, GLUT4, and IRS1, while ADMET prediction indicated acceptable pharmacokinetic behaviour and good drug-likeness. Conclusion: The TC:AI 1:1 formulation exhibited synergistic antioxidant and antidiabetic effects, supported by favorable in-silico interactions and pharmacokinetic profiles, highlighting its potential as a natural therapeutic option for T2DM management.

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.

Background: Tinospora cordifolia (Willd.) Miers, belongs to Menispermaceae, commonly known as \“Guduchi\”or \“Amrita\” and has immense importance in Ayurvedic medicine. Several studies have been carried out on pharmacology, pharmaceutical, anticancer activity and clinical trials of T. cordifolia, however not much information is available on the adulterants that are added with the genuine plant. Considerable work has been done on pharmacognosy but very few studies have been performed on the anatomy of T. cordifolia. Objectives: Comparative micro-morphoanatomical analysis of T. cordifolia and P. daemia, is important for quality control of fresh and dried samples of the root, stem and leaves. Material and Methods: The plant materials of T. cordifolia and P. daemia were collected, and identified. Fixed sample subjected to cryostat microtomy and sections were observed under light microscope. Micromorphology were studied by light as well as scanning electron microscope. Results: Anatomical studies are cheap and important tool for identification of the correct medicinal plant. Adulterant plant does not contain active principles like Berberine and Tinosporin nor have similar morpho-anatomical characters. Because of the similar appearance and resemblance of dried adulterant plant samples, medicinally important T. cordifolia often get adulterated with other plants. SEM study revealed morpho-anatomical differences like the abundance of starch in cortical and ray parenchyma, different types of trichomes, etc. Cryostat techniques were used for sectioning and showed the presence of xylem plates with wide multicelluar rays. Conclusion: Morphological and anatomical differences were observed in T. cordifolia and P. daemia. The given results showed significant differences therefore this study aims to help in accurate identification and avoid adulteration of a medicinally important plant.
