Chemical constituents of Stachys parviflora

The work embodied in this book is mainly concerned
with the isolation and characterization of chemical
constituents of Stachys parviflora, Linn., which
belongs to the family Lamiaceae (formerly called
Labiateae). The isolated compounds, whether new or
have been previously reported in the literature,
were characterized by using different spectroscopic
techniques including 1H NMR, 13C NMR, DEPT, HMQC,
HMBC, COSY 45 ,NOESY, EI-MS, FAB-MS, IR and UV.

The studies on Stachys parviflora Linn., resulted in
the isolation and characterization of thirteen
compounds consisting of five new including one
benzene derivative, one flavone glycoside and three
triterpenoidal saponins, along with eight known
compounds including two monoterpenoids, three
flavone glycosides, one triterpene, two sterols and
one steroidal saponin. All the known compounds have
not been reported from this plant because no work
was previously done on this specie of Stachys.
The new constituents isolated are parvifloroside B
(55), stachyfloroside A (56), stachyssaponin A
(57), stachyssaponin B (58) and stachyssaponin C
(59).
