Crude extract benalu duku leavesFigure 1 to Figure 4 at below obtained that LC ESI-MS of extract methanol benalu duku leaves were containing identic active substances of medroxy progesterone acetate, progesterone, megestrol acetate and dydrogesterone.

 

Discussion

Analysis by retention time and ESI (m/z) of LC ESI-MS were apparently just two of progesterone like effect substances on crude extract methanol benalu duku leaves that very identic substances to reference material namely medroxy progesterone acetate and progesterone. Other progesterone like effect substances as a megestrol acetate and dydrogesterone on crude extract methanol benalu duku leaves were mostly identic to reference material of megestrol acetate and dydrogesterone by different shift at 0.01 and 0.6 retention time of reference materials. Difference in retention time shift is closely linked nature of polarity samples bound to the column Hypersil Gold of LC. Thus the most likely molecular structure of megestrol acetate and dydrogesterone on methanol extract of benalu duku no resemblance to 100% identically as reference materials of megestrol acetate and dydrogesterone. Analysis to compare between the values of molecule ion fragments (m/z) and ESI (m/z) reference materials of fourth progesterone like effect substances versus identically substances of progesterone like effect on crude extract methanol benalu duku leaves were apparently have a differences values (p<0.05). The molecule ion fragments values were apparently lowest than ESI values as represented at Table 3.

Crude extract benalu duku leavesFigure 1 to Figure 4 at below obtained that LC ESI-MS of extract methanol benalu duku leaves were containing identic active substances of medroxy progesterone acetate, progesterone, megestrol acetate and dydrogesterone.

 

Discussion

Analysis by retention time and ESI (m/z) of LC ESI-MS were apparently just two of progesterone like effect substances on crude extract methanol benalu duku leaves that very identic substances to reference material namely medroxy progesterone acetate and progesterone. Other progesterone like effect substances as a megestrol acetate and dydrogesterone on crude extract methanol benalu duku leaves were mostly identic to reference material of megestrol acetate and dydrogesterone by different shift at 0.01 and 0.6 retention time of reference materials. Difference in retention time shift is closely linked nature of polarity samples bound to the column Hypersil Gold of LC. Thus the most likely molecular structure of megestrol acetate and dydrogesterone on methanol extract of benalu duku no resemblance to 100% identically as reference materials of megestrol acetate and dydrogesterone. Analysis to compare between the values of molecule ion fragments (m/z) and ESI (m/z) reference materials of fourth progesterone like effect substances versus identically substances of progesterone like effect on crude extract methanol benalu duku leaves were apparently have a differences values (p<0.05). The molecule ion fragments values were apparently lowest than ESI values as represented at Table 3.

Note: Superscript a vs., b of molecules ion fragment vs., ESI at the same Table were significant different at p<0.05 by t. test method

The differences of the values between both of them were caused difference technology of sensing ion molecule analytes after ionization on ionized chamber by molecule ion fragments method versus ESI method of LC. The level of sensitivity of the mass range of the device ESI LC-MS Accela TSQ known to the value of m / z 3000 with accompanying Quantitation-Enhanced Data-Dependent MS / MS (QED-MS / MA) capable of monitoring up to create three points of data. Behavior noisy devices have also been suppressed due to the development of techniques such section curved space after ionization chamber (collision unit cell) made ​​900. Study the TSQ Quantum robustness Access Ion Relative Standard Deviation reaches% = 2.9% (THERMO SCIENTIFIC, 2007).

Composition of the crude extract benalu duku leaves at 0.0656 µg/ml were apparently containing progesterone like effect substances at majority component of medroxy progesterone acetate (0.062 µg/ml) after that the second levels as a progesterone (0.028 µg/ml) and the third level namely megestrol acetate (0.003 µg/ml) and dydrogesterone as a minority compounds at 0.0009 µg/ml. That composition of the progesterone like effect on crude extract methanol benalu duku leaves already predicted by BAMBANG, LAZUARDI (2014)., at look after the implication of samples at adult female rat with resulted progesterone hormone at twice level than usual level.

Conclusions

The crude extract methanol benalu duku leaves containing identic substances as a Medroxy progesterone acetate at about 66%, progesterone at about 30%, megestrol acetate at about 3% and dydrogesterone at about 1%. The absolutely identic compounds were obtained at medroxy progesterone acetate and progesterone. But the less than absolute identic compound were obtained at megestrol acetate and dydrogesterone. Recommended of the research result as follows: i., for next research must be explored isolation and identification of the active compound as a progesterone like effect to influenced the physiologic animal subject.
