Nucleosides from Acorus tatarinowii and Their Transformation Pathway
To study the water soluble chemical constituents in rhizoma of
Acorus tatarinowii
and transformation pathway of nucleosides in the process of water extraction.
Method
2
Compounds were isolated and purified by column chromatography on macroporous resin,Sephadex LH-20,ODS and preparative HPLC. Their structures were identified on the basis of physicochemical properties and spectral data. Nucleosides were identified from aqueous extract of
A. tatarinowii
,and their stability was investigated by HPLC. The possible transformation pathways of nucleosides in aqueous extract of
A. tatarinowii
were studied by nucleotide addition test.
Result
2
Eleven compounds including four nucleosides,four phenylpropanoids,two alkaloids and a furfural were isolated,and identified as uridine(
1
),adenine(
2
),guanosine(
3
),adenosine(
4
), 5-hydroxymethylfurfural(
5
),5-(hydroxymethyl)-1H-pyrrole-2-carboxaldehyde(
6
),(threo)1',2'-dihydroxyasarone(
7
),(erythro)1',2'-dihydroxyasarone(
8
),acoraminol A(
9
),acoraminol B(
10
),and tatarine A(
11
). The chromatographic peaks of compounds
1
-
4
and cytidine were identified from aqueous extract of
A. tatarinowii
by HPLC. After ultrasonic extraction for 0.5 h,the stability of nucleosides in water was poor. After ultrasonic extraction for 3 h or refluxing extraction for 0.5 h,the stability of nucleosides in water was good. Four transformation pathways including 5'-cytidylic acid→cytidine,uridine monophosphate→uridine,guanosine monophosphate,guanosine and adenosine-5'-monophosphate,adenosine 5'-diphosphate,adenosine 5'-triphosphorate,adenosine,adenine might exist in water extract of
A. tatarinowii
.
Conclusion
2
Compounds
1
-
4
and
6
were isolated from the genus
Acorus
for the first time. These compounds further enriched the chemical constituents of
A. tatarinowii.
