Mother lode

It will be a little tricky but one can also try to purify by freezing I The sassafras oil is thrown into the freezer to chill. Safrole itself freezes at -14°C so anything that starts to freeze prior to that can be cold filtered in a prechilled vacuum filtration setup. The filtrate goes back in the freezer until -14°C is reached and the mother lode of safrole freezes up. This again is filtered cold but this time the frozen mass of safrole crystals are washed with some ice cold methanol or ethanol (preferably at -14°C) to wash away the unfrozen high-boiling constituents. 

Such a measurement can tell us about the chemical evolution of oxygen, such as whether the isotopes differentiated via a thermal cycle in which lighter leO fractionates from the heavier lsO, much as Vostok ice-core oxygen ratios reveal the Earth s prehistoric climate. From this fixed point of the Sun s oxygen ratios, we can then trace the history of water in other planetary bodies since their birth in the solar nebulae through the subsequent cometary bombardment [13]. In NASA s search for water on the Moon, important for the establishment of a future Moon base, such isotopic ratios will determine whether the water is a vast mother lode or just a recent cometary impact residue.

CHILD. Quite often the Hermetic Chemists have given this name [Enfant] to their Sulphur, but sometimes they bestow the same name upon their Mercury. The Four Children of Nature are the Four Elements, to which Mercur attaches herself in order to form all sublunary beings.. . . Alchemical Philosophers have found that this Child is formed by Nature, and that their secret operation consists of wrenching this child from its matrix or mother-lode then they nourish it with the...

Gold veins in rocks are known as lode deposits. The principal vein is the mother lode , now a figure of speech as well as the name of one of the most famous deposits of the Californian Gold Rush. When these lodes form at relatively low temperatures and low pressures near the surface of the Earth s crust, they can become exceptionally rich in gold. Such deposits can be found in Colorado and Nevada, and became known in the nineteenth century by the Spanish word for prosperity bonanza, a term now redolent with the mythology of the Wild West.

So far we have not learned anything from the NOE data except to assign all of the protons. This is an essential first step, but the real goal is to extract distances between specific pairs of protons from the NOE data. Sequential NOEs are not very useful because we already know that an amino acid residue is close in space to its nearest neighbor in the sequence. The real mother lode of the NOESY data consists of the medium-range (i -> i + 2, i —> i + 3 and i -> i + 4) and long-range connectivities. These define the secondary structure... 

The state of knowledge of these oxide systems is not yet ready for a full review. Rather, this discussion sketches the present state of knowledge which is fairly complete for some oxide systems, skimpy for others, and virtually nonexistent for a few, with the hope that it shall be continued until this mother lode shall have been emptied of her treasure. 

The mother lode of eugenol is going to be found in the West Indian bay oil of the Dominican Republic and surrounding nations. Eugenol content ranges from 38.6 - 75% [38].
