Specificity
The specificity of the method was ascertained by analyzing the
standard drug and sample. The spots for ursolic acid, betulinic
acid, stigmasterol and lupeol in samplewere confirmed by comparing
the RF values and spectra of the spot with that of standard. The
peak purity of ursolic acid, betulinic acid, stigmasterol and lupeol
were assessed by comparing the spectra at three different levels,
i.e., peak start, peak apex and peak end positions of the spot

KekhususanKekhasan metode dipastikan dengan menganalisisobat standar dan sampel. Tempat untuk asam ursolat, betulinicasam, stigmasterol dan lupeol di samplewere dikonfirmasi dengan membandingkannilai-nilai RF dan spektrum spot dengan standar. Thepuncak kemurnian asam ursolat, asam betulinic, stigmasterol dan lupeoldinilai oleh membandingkan garis-garis spektrum pada tiga tingkat yang berbeda,yaitu, mulai puncak, puncak puncak dan posisi akhir puncak spot
