“…The research on plants of medicinal importance is rapidly increasing at National and International level. [1][2][3] Use of plants as a source of medicine has been inherited and is an important component of the health care system in India. In the Indian systems of medicine, most practitioners formulate and dispense their own recipes; hence this requires proper documentation and research.…”

The aim of the present study was to evaluate physicochemical and phyto chemical analysis of different parts (ripe seed, unripe seed, ripe peel, unripe peel and stem) of Indian mango (var. 'Kesar') collected from Saurashtra region of Gujarat. The physiochemical properties such as loss on drying, total ash value, acid insoluble ash value, water soluble ash value and extractive values were carried out. The phytochemical properties such as alkaloids, flavonoids, tannins, phlobatanins, triterpenes, steroids, saponins and cardiac glycosides were also carried out. In phytochemical analysis, tannins showed maximum amounts in all five parts. The present study provides the details physicochemical and phytochemical properties of different parts of kesar mango which are useful in laying down standardization and pharmacopeia parameters.

“…The extraction yield patterns of each identified metabolite across the extraction temperature profile were graphically described by the box-and-whiskers plots using IBM SPSS software version 22 (SPSS/IBM, Chicago, Illinois) (Khoza et al, 2015). A one-way analysis of variance (ANOVA) was performed to test for differences in the recovery patterns of identified metabolites across the different extraction temperatures using the above mentioned statistical software.…”

“…A one-way analysis of variance (ANOVA) was performed to test for differences in the recovery patterns of identified metabolites across the different extraction temperatures using the above mentioned statistical software. Mean values of extraction yields were compared by Tukey's post hoc test and means were deemed to significantly differ if p ≤ 0.05 as indicated on the box-and-whisker plots (Khoza et al, 2015). In order to perform multivariate data analysis, i.e.…”

The need for greener extraction procedures that are quick and efficient has prompted the evolution of pressurized hot water extraction (PHWE). Here, the extraction of flavonoids from Bidens pilosa was demonstrated using PHWE at 50°C, 100°C and 150°C. The extracts were analyzed on UPLC-qTOF-MS/ MS and 28 flavonoids of different classes were identified. Further analysis of the data using principal component analysis revealed differential distribution patterns of the identified molecules. In overall, the extraction yield increased proportionately with increasing temperature. It can thus be deduced that PHWE is an excellent extraction method of flavonoids from plant tissues. Again, this study reiterates B. pilosa as a rich source of flavonoids. Extracción con agua caliente presurizada y huella quimiométrica de flavonoides de Bidens pilosa mediante espectrometría de masas en tándem por UPLC RESUMEN La necesidad de procedimientos de extracción más ecológicos que sean rápidos y eficaces ha impulsado la evolución de la extracción con agua presurizada (PHWE). Se demostró la extracción de flavonoides de Bidens pilosa utilizando PHWE a 50, 100 y 150°C. Los extractos fueron analizados por UPLC-qTOF-MS/MS y se identificaron 28 flavonoides de diferentes clases. Un análisis posterior de los datos utilizando el Análisis de componentes principales reveló los patrones de distribución diferenciales de las moléculas identificadas. En general, el rendimiento de extracción incrementó proporcionalmente con el aumento de la temperatura. Por lo tanto, podría deducirse que PHWE se trata de un excelente método de extracción de flavonoides de tejidos vegetales. De nuevo, este estudio reitera que B. pilosa se trata de una fuente rica en flavonoides.

“…A higher recovery of total antioxidants was achieved from grape pomace by increasing the extraction temperature [101]. Despite the increase in efficiency by increase in temperature, excess temperatures can result in degradation of thermolabile analytes, hence the need for optimization [100,102].

Aflatoxin-Control, Analysis, Detection and Health Risks

Aflatoxins (AFs) are well-known mycotoxins and contaminants of various agricultural commodities globally that are linked to a wide range of adverse health and economic complications. Because of their incessant proliferation and deleterious consequences, it has become mandatory to routinely monitor the levels of these toxins in agricultural products before they go into the market. Essentially, effective analysis is an important component of AFs control, and extraction is a necessary step for their analysis, irrespective of the protocol adopted. Conventional methods for AF extraction are expensive, the processes involved are tedious and utilize large quantities of organic solvents that are environmentally unfriendly. This has necessitated the quest for alternatives that are 'green', cost-effective and easy to perform. In this regard, subcritical water extraction (SWE) is a viable alternative that has proven to be effective in the extraction of other bioactive compounds. This chapter presents a critical appraisal of the principles and dynamics of SWE, and its current applications as a viable tool in the extraction of AFs from various biological matrices. Although further research needs to be performed to enhance its applicability, the adoption of SWE in the extraction of AFs seems very promising and needs to be properly exploited.
