Chemical Constituents from Sprout of Ziziphi jujuba var. spinosa
To investigate the chemical constituents from sprout of
Ziziphi jujuba
var.
spinosa
and explore the effect of germination on the activity of
Z
.
jujuba
var.
spinosa
seed from the perspective of material basis.
Method:
2
The dry sprout of
Z
.
jujuba
var.
spinosa
was crushed and extracted with petroleum ether to remove oils and fats
then the residues were dried and received reflux extraction with methanol. The solvent was decompressed and recovered to obtain methanol fractions. The fractions were dissolved
isolated and purified by column chromatography technologies such as silica gel
RP C
18
and Sephadex LH-20
and the structures of the compounds were identified by nuclear magnetic resonance (NMR)
mass spectrometry (MS) and reference liteature.
Result:
2
The 13 compounds were isolated from the sprout of
Z
.
jujuba
var.
spinosa
and identified as jujuboside B (1)
jujuboside D (2)
jujuboside A (3)
betulinic acid (4)
betulin (5)
lupeol (6)
alphitolic acid (7)
ceanothic acid (8)
oleanolic acid (9)
ursolic acid (10)
magnoflorine (11)
nuciferine (12) and swertisin (13).
Conclusion:
2
All the above compounds were isolated from the sprout of of
Z
.
jujuba
var.
spinosa
for the first time. The study showed that the chemical constituents from the sprout were quite similar with those from the seeds of
Z
.
jujuba
var.
spinosa
mainly including triterpenoids and saponins
flavonoids
alkaloid
etc.Overall
the results described in this study could provide certain chemical basis for further resources exploitation and utilization of the sprout of
