little sulphuric acid; the base as well as its salts are very similar in
its properties pp to quinicine, q , and its salts.
Pti Paytine C^H^lLOj CHlLO + H«0 H0 has h bbeen
found in a white bark from
Payta; it forms white needles or prisms, and possesses left-handed
polarization. By adding bleaehiug-powder to its acid solution, it
colours first red, and then blue, but the colour very soon disappears.
Paridne occurs in the red barks from India, and in other barks. It
is yellowish-white powder, which readily dissolves in ether and
alcohol; its composition is not known.
ALKALOIDS OCOUMJING IN CHEUD0N1UM MAJUS.
The common celandine contain two bases.
Ghelevyllvrine G1M11NOi exists also in the root of Sanguinaria
canadensia and in Gflameum Iviewn. It crystallizes from alcohol in
warty masses, possessing a very acrid taste; it is poisonous, and its
dust produces violent sneezing. Its salts have a red colour, and give
with -water an orange-red solution.
Ghelidonine C19Hl7NaO8 + H20 crystallizes from alcohol in glistening
plates, having a bitter taste; it is not poisonous, and forms
colourless salts.
ALKALOIDS QCCCRK1NG IN VERATRUM.
Veratrine CS2H8gN2Og exists in the seeds of Vcrafncm SabadUla
and in the root of Veratrum album. It is almost insoluble in water,
but dissolves in ether, and alcohol, and crystallizes in white prisms,
melting at 115°, and solidifying again^o a resinous mass. Veratrin
is a most violent poison, and its dn'et produces violent sneezing.
With concentrated sulphuric acid it forms a yellow solution which
gradually becomes blood-red.
Jervine CjoH^NgOg occurs only in Veratrum album., and forms
colourless prisms; its salts are much less soluble than those of
veratrine.
ALKALOIDS 0CCTJBR1NG IK BEBBEK1S VULGAB1S.
Bcrbenne CJOH^NO^ + SHgO exists in the root of this shrub, and
also in the roots of Coecuhis palmatvs and Hydrastis canadensis. Jt
is soluble in water and alcohol, and crystallizes in yellow needles,
possessing, as well as its yellow salts, an intensely bitter taste.
By the action of zinc and dilute sulphuric acid, it is converted into
