Simultaneous determination of 5 kinds of pentacyclic triterpenoids in Chaenomeles speciosa by quantitative analysis of multi-components by single-marker
To establish a method for simultaneous determination of 5 kinds of pentacyclic triterpenoids as 3-
O
-acetyl-pomolic acid in
Chaenomeles speciosa
, and to analyze the difference in the contents of
C. speciosa
fro
m different producing areas by different processing technologies.
METHODS
2
HPLC method was adopted. The determination was performed on COSMOSIL 5 C
18
-MS-Ⅱ column with mobile phase consisted of acetonitrile-0.005 mol/L ammonium dihydrogen phosphate solution (pH value adjusted to 6.5 with phosphoric acid)(70∶30,
V
/
V
) at the flow rate of 1.0 mL/min. The column temperature was set at 30 ℃. The detection wavelength was set at 210 nm, and sample size was 20 μL. The contents of the other four pentacyclic triterpenoids were calculated according to quantitative analysis of multi-components by single-marker (QAMS) using oleanolic acid as internal reference. The results were compared with those determined by external standard method. The total content of oleanolic acid and ursolic acid, the total content of 5 components in
C. speciosa
from different producing areas and different processing technologies were compared.
RESULTS
2
The linear range of 3-
O
-acetyl-pomolic acid, betulinic acid, oleanolic acid, ursolic acid and 3-
>0.999). RSDs of precision, reproducibility and stability (24 h) tests were all lower than 3%. The average recoveries were 98.29%-101.38%(RSDs<3%,
n
=6). The mass fraction of 3-
O
-acetyl-pomolic acid, betulinic acid, ursolic acid and 3-
O
-acetyl ursolic acid measured by QAMS were 0.023%-0.060%, 0.044%-0.528%, 0.101%-0.368%, 0.067%-0.221%, respectively; the deviations from the results measured by external standard method were all within 8%. The total content of oleanolic acid and ursolic acid, the total content of 5 components in
C. speciosa
processed by fresh-cut technology from the same producing area were higher than those in
C. speciosa
processed by traditional technology, and the total content of 5 components in
C. speciosa
from Chongqing Qianjiang were significantly higher than those from other producing areas (
P
<0.05).
CONCLUSIONS
2
QAMS method is established for the simultaneous determination of 3-
O
-acetyl-pomolic acid, betulinic acid, oleanolic acid, ursolic acid and 3-
O
-acetyl ursolic acid in
C. speciosa.
Established method is simple, rapid and accurate. The total content of 5 components in
C. speciosa
produced in Chongqing Qianjiang is higher, and the total content of
C. speciosa
processed by fresh-cut technology from the same origin is higher than
