“…The spectrum exhibited peaks at 2920 and 2852 cm -1 for asymmetric and symmetric stretching vibrations of CH 2 and CH 3 [11], 1436 cm -1 for CH 2 scissoring and 1361 cm -1 for splitting due to dimethyl group. The FT-IR spectrum of LUT also showed peaks at 1024 cm -1 for in plane -CH- [12] and 962 cm -1 for trans conjugated alkene -CH=CH-out of plane deformation mode [13]. …”

Lutein (LUT) is one of the most important carotenoid and; the most prominent being its antioxidant activity. However, its use is limited due to poor solubility and instability under adverse conditions. An attempt is made to increase the solubility and hence bioavailability of LUT using various cyclodextrins viz., betacyclodextrin (bCD), hydroxypropyl betacyclodextrin (HP-bCD) and methyl betacyclodextrin (M-bCD). Physical mixtures and spray dried inclusion complexes were prepared and characterized using spectroscopic techniques, DSC and XRD studies. From the phase solubility and dissolution studies it was found that, M-bCD significantly improved the solubility of LUT. These complexes were further subjected to in vitro anti-proliferative activity in order to validate results obtained from solubility studies. The biological results were in congruence with the results of solubility studies. Spray dried complex of LUT:M-bCD showed significant percent growth inhibition as compared to other two complexes and LUT alone. Molecular modeling studies established the hostguest stoichiometry with the lowest energy to be 2:1, with the two hexatomic rings of a LUT molecule occupying the two M-bCD cavities. The present study forms the basis for the development of oral formulations of LUT with significantly improved solubility and bioavailability.

Vibrational spectroscopy may be applied to the qualitative and quantitative analysis of complex food systems. Mid infrared (MIR) spectroscopy and Raman spectroscopy are valuable tools for identification and structural characterization of food components and for elucidating structure–function relation of food biopolymers such as proteins. Fourier transform infrared(FT‐IR) spectrometers and chemometrics have broadened the scope of MIR spectroscopy for quality control analysis, but such applications remain generally limited to homogeneous fluid products such as beverages, juices, fats, and oils. In contrast, near infrared (NIR) and FT‐NIR spectroscopy in conjunction with multivariate calibration techniques is becoming increasingly popular in the food industry for rapid and routine analysis of proximate composition of various foods as well as for authentication and detection of adulteration. Increasing application of Raman spectroscopy in food analysis is expected with recent developments in NIR‐FT Raman spectrometers, fibre optic sampling, and confocal Raman microscopy.

“…Moh et al [85] described how the FT-IR spectrum for β-carotene exhibited peaks at 2922 cm -1 and 2862 cm -1 due to the asymmetric and symmetric stretching vibrations of the CH 2 and CH 3 groups. Thus, in the present study, the peaks at 2926 cm -1 and 2860 cm -1 could correspond to carotenoids; as well as the peaks at 1442 cm -1 (due to CH 2 scissoring), 1369 cm -1 (due to splitting the dimethyl group).…”

The principal goal of astrobiology is the search for extraterrestrial life forms. A key aspect is the study of the ability of different kinds of terrestrial organisms to support simulated extraterrestrial environmental conditions. Mosses are multicellular green plants, poorly studied from an astrobiological perspective. In this paper, we report experimental results obtained using two species of moss, which demonstrate that both the spores of the moss Funaria hygrometrica as well as the desiccated vegetative gametophyte shoots of the moss Tortella squarrosa (=Pleurochaete squarrosa) were capable of resisting Simulated Martian Environmental Conditions (SMEC): Mars simulated atmospheric composition 99.9% CO 2 , and 0.6% H 2 O with a pressure of 7 mbars, -73 º C and UV irradiation of 30 mW cm -2 in a wavelength range of 200-400 nm under a limited short time of exposition of 2 hours. After being exposed to SMEC and then transferred to an appropriate growth medium, the F. hygrometrica spores germinated, producing typical gametophyte protonemal cells and leafy shoots. Likewise, detached leaves from SMEC-exposed gametophyte shoots of T. squarrosa retained the ability to produce new protonemata and shoots under suitable growth conditions. Furthermore, we studied the tolerance of these moss structures to a thermal stress of 100 °C for 1 h; in both cases the spores and shoots were capable of resisting this heat treatment. Our study using FT-Raman and FT-IR vibrational spectroscopy demonstrated that neither spores nor shoots apparently suffered significant damage in their biomolecular makeup after being subject to these stress treatments. The implications of these findings for the search of life on Mars are discussed.
