Abstract Background: Ayurvedic medicines help in healing disease with fewer undesirable effects in comparison with an allopathic system of medicine to treat central nervous system (CNS) disorders, as the latter is more expensive. Centella asiatica L. is often used in Ayurvedic formulations for the treatment of CNS disorders. Objective: A stability test using an HPTLC method for the estimation of an important marker asiaticoside (ASI) from C. asiatica powder and marketed formulation was developed. Methods: The marker compound ASI from plant powders and marketed formulations were resolved using toluene–ethyl acetate–methanol–glacial acetic acid (2+7+3+1, v/v/v/v) as the mobile phase and then was derivatized. The plant powder and marketed formulation were also subjected to stability studies. Results: The Rf value of ASI was found in range of 0.43–0.47 for the standard ASI, plant powder, and marketed formulation. It was found that the plant powder and formulation exhibited first-order degradation kinetics. Conclusions: The contents of ASI in the formulation (Churna) and its flow characters reduced at the end of the 6 months during an accelerated stability study. The developed method can be used to quantify ASI in the presence of its degradation products. Highlights: The developed method helps in determining batch to batch variation in the content of ASI in herbal formulations.

This work is the first study of adoption of GM crops by French farmers. The GM crop technology case was a fertile field for the study of technology adoption but existing literature mainly focuses on studies of these issues in USA, Africa and Asia. In France, main production area of maize in Europe, the agricultural sector is very atypical compared to the agricultural sector investigated in the existing literature on the GMO adoption. By a study of the GM crop adoption in the French context and within the main production area, the south-west region of France, this study reveals 4 determinant factors that shape the choice of GM or NGM maize cropping. Some of the factors pointed by this study are in line with the existing literature on technology adoption and output uncertainty and input uncertainty (uncertainty on the expected marginal benefits and costs to sustain the new technology). Other factors identified under the atypical French agriculture sector distinctive features are particularly novel. These new factors are linked to the implementation of the UE regulation on GM/NGM coexistence in the context of small fragmented farms (need of coordination between farmers to prevent GM dispersal) and importance of the market outlets proximity to federate farmers. These novel results pinpoint that in the French context there is a need of both vertical coordination (farmers with the operators downstream the supply chain as the outlet industrial) and horizontal coordination (among farmers in neighbourhood situation) to foster the technology adoption in such industry context.
