The fact that the lowest fractionl yielded no nitroso-chloride may be explained by
assuming the presence of laevogyrate pinene. It has been shown by Mr. Smith
that strongly laevogy- rate pinene does not yield a crystallizable introso-chloride,

The dextrogyrate salts yielded a laevogyrate acid, which, like sarcolactic acid,
yielded an oppositely active anhydride. The laevogyrate salts obtained from the
more soluble strychnine salts were mixed with much inactive lactate, which ...

Furthermore, the authors' investigations show that crystalline bebeerine from
Pareira brava may exist in both the laevogyrate and dextrogyrate form, as well as
in an optically inactive (racemic) form, and that both optically active forms may
exist ...

treatment with acetic acid anhydride the optical activity was changed to +20°; by
treatment with phosphorus pentoxide it was changed to —10°. Further, they were

The viscid oxime from the dextrorotatory menthone obtained by the action of
acids upon laevogyrate menthone would hardly appear to be a uniform
compound and may be due to the fact that dextrorotatory menthone is a mixture
of geometric ...

When the chloride, however, is submitted to different operations, as for instance
to repeated distillation, or when the temperature at its formation was a high one,
the chloride is but very little laevogyrate, and yields, when acted upon by bases, ...
Blachstein found in the cultures of typhoid bacillus a laevogyrate para-lactic acid,
the zinc salt of which was dextrogyrate, and that the lactic acid produced by the
colon bacillus was dextrogyrate and the corresponding zinc salt laevogyrate.
Harold Nicolas Moyer, 1895
Of the laevogyrate products fractions 210—215° and 215—220° were thus
dehydrated, of the dextrogyrate products fractions 205 to 210°, 210—212°, 212—
214° and 214-216°. The results are herewith tabulated : Laevogyrate
Dehydration ...

The solubility of ordinary dextrogyrate camphoric acid is practically identical with
that of the laevogyrate acid from feverfew camphor, but very different from that of
the laevogyrate acid obtained by heating the dextrogyrate acid in presence of ...
