The Impact

This study aimed to study the impact of selected common organic solvents on extractable solids, phytochemical composition, and antioxidant capacity of S. chinensis. The results showed that the tested solvents played an important role in extraction of total solid and phytochemical composition as well as antioxidant capacity of S. chinensis. Acetone (50% v/v) was found to be the optimal extraction solvent for extractable solids (12.2%), phenolic compounds (60 mg GAE/g DW), flavonoids (100 mg CE/g DW), proanthocyanidins (47.4 mg CE/g DW), and saponins (754 mg EE/g DW) as well as antioxidant capacity (ABTS 334 mM TE/g DW, DPPH 470 mM TE/g DW, FRAP 347 mM TE/g DW, and CUPRAC 310 mM TE/g DW). The extract prepared from 50% acetone had high levels of bioactive compounds (TPC 555 mg GAE/g CRE, flavonoids 819 mg CE/g CRE, proanthocyanidins 392 mg CE/g CRE, and saponins 1,880 mg EE/g CRE) as well as antioxidant capacity (ABTS 414 mM TE/g, DPPH 407 mM TE/g, FRAP 320 mg TE/g, and CUPRAC 623 mM TE/g), thus further confirming that 50% acetone is the solvent of choice. Therefore, 50% acetone is recommended for extraction of phenolic compounds, their secondary metabolites, saponins, and antioxidant capacity from the root of S. chinensis for further isolation and utilisation.

Etlingera Elatior

Objective: This study was carried out with an objective to investigate the impact of biochar on phytochemical composition in plant especially Etlingera elatior cultivated on different dosage of biochar. Methods: Etlingera elatior was cultivated on the pot with 20 cm diameter and 35 cm height. 3 replicates for pots of Etlingera elatior was cultivated and label as 0%, 5% and 20%. The ordinary farm soil without biochar (0%) as control, fertilized soil with biochar; 5% and 20%. In a net house and watered twice daily. The gas chromatography mass spectrometry analysis was performed by using a non-polar BPX-5 capillary column with an initial temperature of 50°C hold for five minutes and then increased to 300°C at a rate of 5.0°C per minutes and hold 10 minutes. The biochar samples were analysed using an ATR-FTIR equipped with diamond crystal, controlled by OMNIC software (Thermo Nicolet Analytical Instruments, Madison, WI). A flat tip powder press was used to achieve even distribution and contact. Results: The result showed significantly increased in the phytochemical composition with increase in the biochar concentration. At 0% phytol (13%), Hexadecanoic acid (9.76%), Neophytadiene (6.51%), coumarin (5.65%), precocene (5.27%) and caryophyllene (4.59%). At 5% are Dihydrocucurbitacin (13.69%), Niacinamide (11.02%), α-Limonene (10.01%), Phyrahen (9.23%), Phytol (7.24%) and Neophytadiene (5.75%) and at 20% Linoleic acid (39.98%), 2-pinen-4-ol (12.32%), Hexatriacontyl pentafluoropropionate (6.89%), Benzofuran (5.12%), Acethophenon (4.41%) and furfural (4.03%). Conclusion: Application of biochar on soil can increase nutrient availability and enhance the development of phytochemical composition in plants. Without biochar, the chemical composition Etlingera elatior extract was slighlyt low. At 5% and 20% biochar, some compounds are increasing and new were obtained compared to 0% biochar. Most of the compounds known to be secondary metabolite which are rich in medicinal values. Thus, biochar could be used to increase the quantity and quality of phytochemicals in plant especially medicinal plants.

The objective of this study was to evaluate the impact of different mixtures of two fresh-cut baby lettuce (Lactuca sativa L. var. crispa cv. Lollo Bionda [LB] and cv. Lollo Rossa [LR]) cultivars on lettuce phytochemical composition during postharvest. Lettuces were grown in a soilless culture system with continuous flotation (FL) in a greenhouse, mixed at harvest and packaged in polypropylene bags and stored at 4 °C for 9 days (d9). Mixes were made of 100, 75, 50, 25 and 0% of LB, respectively. The results showed that the phytochemicals were preserved during storage. In specific, 25LB had the highest pigment content on d1, while 50LB and 25LB had the highest inherent quality on d1.FL led to a reduced microbial contamination, thus, limiting its growth during storage. The results have revealed that high quality and microbiologically safe baby leaf vegetables (BLV), can be obtained by means of FL. The adopting a mix of lettuce cultivars could represent a positive postharvest practice to preserve the phytochemicals of BLV throughout their shelf life.

Xylopia Aethiopica

Aside from its multiple medicinal uses, the fruit of Xylopia aethiopica is widely used in Africa as food. Herein, we characterize the protein profiles, mineral content and bioactive phytochemical composition of the seeds of this plant sourced in Ghana and Nigeria. Using label-free proteomics, a total of 677 proteins were identified, with 260 found in the Ghana-sourced samples while 608 proteins were detected in the samples from Nigeria. However, 114 proteins were common between the samples from the two countries, among which 48 were significantly changed. Bioinformatics and functional analyses revealed that the differential levels of the proteins were mainly linked to pathways involved amino acids metabolism and biosynthesis. The significantly changed proteins related mainly to catalytic activity and carbon metabolism. The samples from Nigeria also exhibited superior qualities in terms of their antioxidant effects, and total phenolic and flavonoid content. Finally, only the content of Na varied to a statistically significant level. This study lends support to its culinary use and hints towards the impact of location of cultivation on the quality of the seeds. There is however need for further mechanistic investigations to unravel the underlying reasons for the observed differences.

AbstractInterdisciplinary research was carried out on the impact of climate on the diversity and morphology of Stratiotes aloides L. emergent forms’ phenotype in various latitudes. The objectives of the research were: 1. to determine whether the climate influences the diversity of emergent forms, 2. to determine the diversity of morphological and anatomical traits and chemical composition of S. aloides specimens in Poland and Russia, 3. to examine the content of, and determine the correlation between phenols, phenolic acids, flavonoids, anthocyanins, and tannins in S. aloides. The research demonstrated the substantial diversity of 13 morpho-anatomical traits, and 5 phytochemical traits, both between regions, and individual habitats. Principal Component Analysis (PCA) demonstrated different correlation patterns for the analysed substances between regions characterised by different temperature ranges. S.aloides shows substantial abilities to adapt in terms of structure and physiology to the aquatic environment in various climate zones.

The Impact

The phenomena accompanying the impact of large meteorites on the surface of the Moon or of the Earth can be examined on the basis of the theory of explosive phenomena if we assume that, instead of an exploding meteorite moving inside the rock, we have an explosive charge (equivalent in energy), situated at a certain distance under the surface.

The term geo-sciences has been used here to include the disciplines geology, geophysics and geochemistry. However, in order to apply geophysics and geochemistry effectively one must begin with a geological model. Therefore, the science of geology should be used as the basis for lunar exploration. From an astronomical point of view, a lunar terrain heavily impacted with meteors appears the more reasonable; although from a geological standpoint, volcanism seems the more probable mechanism. A surface liberally marked with volcanic features has been advocated by such geologists as Bülow, Dana, Suess, von Wolff, Shaler, Spurr, and Kuno. In this paper, both the impact and volcanic hypotheses are considered in the application of the geo-sciences to manned lunar exploration. However, more emphasis is placed on the volcanic, or more correctly the defluidization, hypothesis to account for lunar surface features.

The Impact

AbstractWhilst lithopanspermia depends upon massive impacts occurring at a speed above some limit, the intact delivery of organic chemicals or other volatiles to a planet requires the impact speed to be below some other limit such that a significant fraction of that material escapes destruction. Thus the two opposite ends of the impact speed distributions are the regions of interest in the bioastronomical context, whereas much modelling work on impacts delivers, or makes use of, only the mean speed. Here the probability distributions of impact speeds upon Mars are calculated for (i) the orbital distribution of known asteroids; and (ii) the expected distribution of near-parabolic cometary orbits. It is found that cometary impacts are far more likely to eject rocks from Mars (over 99 percent of the cometary impacts are at speeds above 20 km/sec, but at most 5 percent of the asteroidal impacts); paradoxically, the objects impacting at speeds low enough to make organic/volatile survival possible (the asteroids) are those which are depleted in such species.
