Embodiment 1

[0022] Crush the bamboo leaf pepper into coarse grains. Take 100g of bamboo leaf pepper coarse grains, add 0.2% H 2 SO 4 Ethanol, soaked for 24 hours, filtered; the dregs were extracted once more by the same process, filtered; the two filtrates were combined, neutralized with concentrated NaOH until neutral, and concentrated under reduced pressure at 60°C to obtain the extract of bamboo leaf pepper. The ointment yield was 13.04%; the content of magnolanine was 413.77mg / g; the transfer rate of magnolanine was 27.9%.

Embodiment 2

[0024] Crush the bamboo leaf pepper into coarse grains. Take 100g of bamboo leaf pepper coarse grains, add 0.1% H 2 SO 4 Ethanol, soaked for 24 hours, filtered; the dregs were extracted once more by the same process, filtered; the two filtrates were combined, neutralized with concentrated NaOH until neutral, and concentrated under reduced pressure at 60°C to obtain the extract of bamboo leaf pepper. The cream yield was 12.98%; the content of magnolanine was 412.05mg / g; the transfer rate of magnolanine was 27.7%.

Embodiment 3

[0026] Crush the bamboo leaf pepper into coarse grains. Take 100g of bamboo leaf pepper coarse grains, add 0.15% H 2 SO 4 Ethanol, soaked for 24 hours, filtered; the dregs were extracted once more by the same process, filtered; the two filtrates were combined, neutralized with concentrated NaOH until neutral, and concentrated under reduced pressure at 60°C to obtain the extract of bamboo leaf pepper. The yield of ointment was 13.01%; the content of magnolanine was 413.04mg / g; the transfer rate of magnolanine was 28.0%.

Abstract

The invention provides a technology for extracting zanthoxylum pistaciiflorum hayata by utilizing sulfuric acid-ethanol. The technology comprises the following steps: preparing the zanthoxylum pistaciiflorum hayata into coarse grains; adding into 4-6 times of ethanol sulfate solution, soaking for 20-24h and filtering; extracting the drug residue according to the same process and filtering; mixing the two filtrates; neutralizing the filtrates till being neutral by using concentrated NaOH; and reducing pressure and concentrating at 50-60 DEG C, thereby acquiring a zanthoxylum pistaciiflorum hayata extract. A detection test proves that the extract yield of zanthoxylum pistaciiflorum hayata extract and the transfer rate of magnoline are obviously increased according to the technology provided by the invention, the use ratio of the zanthoxylum pistaciiflorum hayata medicinal material is effectively increased, the resource of the zanthoxylum pistaciiflorum hayata medicinal material is saved and the industrialization cost is saved.

Description

technical field [0001] The invention relates to a process for extracting bamboo leaf pepper, in particular to a process for extracting bamboo leaf pepper by using sulfuric acid-ethanol, and belongs to the technical field of extraction and utilization of plant effective components. Background technique [0002] Bamboo leaf pepper (Zanthoxylum armatum DC), a plant of the genus Zanthoxrylumarmatum in the family Rutaceae, also known as Xuejianfei, dog pepper, and wild pepper. Born in sparse forests and bushes in low mountains, distributed in southeast and southwest provinces, northwest to Qinling Mountains. "Dictionary of Traditional Chinese Medicine" records that bamboo leaf pepper is pungent in taste and warm in nature, and has the functions of warming the middle and regulating qi, expelling wind and dampness, promoting blood circulation and relieving pain. Studies in recent years have shown that the fruits, stems, and leaves of Zanthoxylum can extract aromatic oils, which ca...
