| Abstract: | The flavonoids in Jasminum nudiflorum Lindl. extracted by Soxhlet extractor with 75% ethanol was studied by colorimetry and HPLC. Determined by colorimetry with rutin as standard sample, the content of total flavonoids in its flowers, leaves and stems were 13.7%,16.2% and 6.77%,RSD were 2.63%, 2.57% and 2.96% respectively, while determined by HPLC with quercetin, kaempferol, isorhamnetin as standard samples, the content of total flavonoids in its flowers, leaves and stems counted by aglycone were 4.205%, 3.371%, 1.703%, RSD were 1.76%, 1.58% and 1.98% respectively. |
