Oxidative stress in toxic manifestations 

Our research group is involved in exploring potential of standardised medicinal plant extracts/ phytochemicals in mitigating free radical induced damage at the cellular and organelle level. Hepatotoxicity caused by exogenous agents such as drugs/chemicals or endogenous stressors like hyperglycemia pose a major health problem. Recent findings indicate that Nimesulide, a non-steroidal anti-inflammatory drug aggravates redox imbalance and calcium dependent mitochondrial permeability transition leading to dysfunction and hepatotoxicity. Alteration of critical events like cyt c release, Bax/Bcl-2, caspases activation, DNA fragmentation, chromatin condensation and antioxidant status by Fumaria parviflora extract has been established during hepato-protection against Nimesulide stress. Lupeol extracted from Crataeva nurvala and probiotic Enterococcus lactis IITRHR1 showed capacity to abrogate acetaminophen induced hepatotoxicity. Antioxidant and antihyperglycemic effects of Berberis aristata root extract and its role in modulating carbohydrate metabolism has been established in diabetic rats. Plant derived-antioxidants camphene and geraniol have been shown by us to protect alveolar macrophages against oxidative stress. Currently their role in modulating oxidative stress induced Nrf-2 mediated signaling cascade is being studied. 

Safety & efficacy of herbal formulations 

Evaluation of herbal antioxidants and safety of formulations carried out in two drug development projects i.e. CSIR network project "Newer scientific herbal preparations for global positioning" and "Golden Triangle Partnership Project" besides participation as an expert in programme for bioactives from natural sources, for drug development.

Development of Pharmacopoeial standards for 24 Ayurvedic herbal drugs of single plant origin, 17 of which were poisonous medicinal plants. Seven monographs have been published in The Ayurvedic Pharmacopoeia of India, Part-1, Vol.V (2006). 

Creation of a unique Quality Assurance of Medicinal Plants (QAMP) database on heavy metal and persistent pesticide contamination in more than 1900 therapeutically important medicinal plant samples collected from different ecological zones of India. The database has more than 35,000 data generated after extensive analysis in the lab.
