  We reconsider the problem of separation of spin and charge in one dimensional
quantum antiferromagnets. We show that spin and charge separation in one
dimensional strongly correlated systems cannot be described by the slave boson
or fermion representation within any perturbative treatment of the interactions
between the slave holons and slave spinons. The constraint of single occupancy
must be implemented exactly. As a result the slave fermions and bosons are not
part of the physical spectrum. Instead, the excitations which carry the
separate spin and charge quantum numbers are solitons. To prove this {\it
no-go} result, it is sufficient to study the pure spinon sector in the slave
boson representation. We start with a short-range RVB spin liquid mean-field
theory for the frustrated antiferromagnetic spin-${1\over2}$ chain. We derive
an effective theory for the fluctuations of the Affleck-Marston and Anderson
order parameters. We show how to recover the phase diagram as a function of the
frustration by treating the fluctuations non-perturbatively.
