					How colchicine was discovered?

How colchicine was invented? So Covert material …

upstairs landlord does not explain the questions asked! Knowledge only to find
chaos Baidu copy, and I am a student matter should be clear about your
question..

give me answer one by one, first of all, it is not a hidden matter, an
alkaloid, originally from lily plants by colchicine extracted, so name, also
known as colchicine. In the morning of the 20th century had invented the
twenties and thirties, the general squeeze grinding material filtered through
the invention of high purification of access, but do not want to extract the
salt, the process as simple as that. As for why, in from the colchicine
extraction? your question there is a problem, you need to know biology is the
basis of experimental subjects, Yi Shi had many plants used for experiments,
can be said that the substance was obtained by chance he has a magical effect
of the invention, , avoid the Mendelian hybridization experiments with peas to
make a lot prior to the plant used a lot of experiments, this process also
invented a lot of opinions have no direct contact with the hybridization of
the invention, this is the charm of science.

Autumn Narcissus hormone (colchicine) an alkaloid. for the first lily plants
from colchicine (Colchicum autumnale) is extracted, hence the name, also known
as colchicine. formula C22H25O6N. pure colchicine yellow needle crystal form,
melting point 157 ℃. soluble in water, ethanol and chloroform. bitter,
poisonous. colchicine to inhibit mitosis, grinding spindle, the chromosomes in
metaphase arrest. This colchicine caused by the abnormal division, known as
colchicine is known as mitosis (C-mitosis). In this mitosis, the chromosomes
although the slit, but the cell does not split and can not form two daughter
cells, thereby doubling chromosomes. Since 1937, American scholar Blakeslee
(AFBlakeslee), etc. with colchicine chromosome doubling the number of Datura
and other plants to succeed later, colchicine was widely used in cytology,
genetics and plant breeding research to learn the things.

longitudinal chromosome, but the cells do not split the two daughter cells can
not form, thus doubling the chromosome. Since 1937, American scholar Blakeslee
(AFBlakeslee) and so on, doubling with colchicine chromosome number of Datura
and other plants to obtain After the success of colchicine was widely used in
