Abstract:
Chromosome examination was carried out in 30 medical plant species native
to Xinjiang in 14 families, ten of which are traditional medical plants of the minority na-
tionalities in the region, the karyotype analysis was also carried out in some species. Karyo-
type formulae are 2n=12=10Lm+2SstSAT for Nigella glandulifera, 2n=16= 2m+12sm+
2st for Trollius chinensis, 2n= 16 =8m + 8sm for Astragalus membranaceus, 2n=16=10m
6 sm for Astragalus mongholicus, 2n=16=8 m+8 sm for Catharanthus roseus. The
chromosomal numbers of the others are as follows: Dianthus chinensis, 2n=30, Vaccaria
pyramidata, 2n=30, Cassia occidentalis, 2n=26, Psoralea corylifolia, 2n=22, Peganum har-
mala, 2n=22, Acanthopanax trifolitus, 2n=46, Anethum graveolens, 2n=22, Foeniculum
vulgare 2n=22, Trachyspermum ammi, 2n= 18, Agastache rugosus, 2n= 18 Dracocephalum
moldavica, 2n= 10, Leonurus heterophyllus, 2n=20, Ocimum basilicum, 2n=48, schizone-
peta tenuifolia, 2n=24, Atropa belladonna, 2n=60 Nicandra physaloidea, 2n=20, Solanum
surattense, 2n=24, Scrophularia ningpoensis, 2n= 90, Plantago insularis, 2n =8, Gardenia
jasminoides, 2n =22, Platycodon grandiflorus 2n= 18, Cichorium intybus, 2n= 18, Saussuea
involucrata, 2n=32, Silybum marianum, 2n=34, Vernonia anthelmintica, 2n=20. The kar-
yotypes of 8 species are reported for the first time.
