Embodiment 1
[0042] The total nortriterpenoid composition of Rhizoma Rhizoma in this example contains the following weight percentages of compounds 1-6: compound 1: 17.51%, compound 2: 12.35%, compound 3: 10.24%, compound 4: 9.31%, compound 5: 4.57%, compound 6: 4.08%, and the rest are lower content of nortriterpenes and impurities.
[0043] The total nortriterpenes composition of Rhizoma Phragmatis in this embodiment is extracted by the following method:
[0044] 1) Take 1 kg of dry and crushed 60-mesh four-lens hemp (rough persimmon root), add 20 kg of 95% ethanol to extract under reflux conditions for 5 hours, add 95% ethanol to the filtered residue and extract under reflux conditions for 4 hours, Repeat the extraction for a total of three times under reflux, combine the extracts (filtered filtrate), and reclaim ethanol under reduced pressure to obtain 180 g of extract;
[0045] 2) Fully dissolve the extract with 720 grams of petroleum ether-ethyl acetate with a volume ratio of 2:1, fi...
Embodiment 2
[0052] The total nortriterpenoid composition of Rhizoma Rhizoma in this embodiment contains the following weight percentages of compounds 1-6: compound 1: 14.36%, compound 2: 13.65%, compound 3: 11.24%, compound 4: 8.12%, compound 5: 4.21%, compound 6: 3.59%, and the rest are lower content of nortriterpenes and impurities.
[0053] The total nortriterpenes composition of Rhizoma Phragmatis in this embodiment is extracted by the following method:
[0054] 1) Take 2 kilograms of dry and crushed 60-mesh four-lens hemp (rough persimmon root), add 30 kilograms of 90% ethanol to extract under reflux conditions for 4 hours, add 90% ethanol to the filtered residue and extract under reflux conditions for 3 hours, Repeat the extraction for a total of reflux extraction four times, combine the extracts (filtered filtrate), recover ethanol under reduced pressure to obtain 395 g of extract;
[0055] 2) The extract was fully dissolved with 1975 g of petroleum ether-ethyl acetate with a volu...
Embodiment 3
[0062] The total nortriterpenoid composition of Rhizoma Rhizoma in this embodiment contains the following weight percentages of compounds 1-6: compound 1: 13.23%, compound 2: 14.05%, compound 3: 12.04%, compound 4: 8.24%, compound 5: 4.87%, compound 6: 4.25%, and the rest are lower content of nortriterpenes and impurities.
[0063] The total nortriterpenes composition of Rhizoma Phragmatis in this embodiment is extracted by the following method:
[0064] 1) Take 3 kilograms of dry and crushed 60-mesh four-lens hemp (rough persimmon root), add 30 kilograms of 85% ethanol to extract under reflux conditions for 3 hours, and then extract the filtered residue with 85% ethanol for 5 hours under reflux conditions, Repeat the extraction for a total of five times of reflux extraction, combine the extracts (filtered filtrate), and reclaim ethanol under reduced pressure to obtain 624 g of extract;
[0065] 2) Fully dissolve the extract with 1872 g of petroleum ether-ethyl acetate with a...
