Embodiment

[0032] 26kg of flax root is crushed into a particle size of 1×1cm 2 After the purpose, reflux extraction with 6 times the amount of 95% ethanol for 3 times (2h, 1h×2), filter the extract, combine, concentrate to a paste, dissolve with 4000mL distilled water, and extract three times with ethyl acetate (2000mL, 1500mL ×2), n-butanol extraction three times (2000mL, 1500mL×2); the obtained n-butanol extract was concentrated to about 3000mL, then extracted three times with 5% aqueous sodium bicarbonate (1500mL, 1000mL×2), and then water Extract to neutrality (1000mL×2), recover n-butanol under reduced pressure to obtain brown n-butanol extract, which is crude cerebroside extract (31g).

[0033] Take 30 g and use 10 times the amount of 200-300 mesh silica gel for column chromatography separation, use chloroform / methanol (100:1-5:1) solvent system for gradient elution, collect 1 part per 250ml, 1 H NMR detection, merging the same fractions to obtain β-carotin (980mg) at 61-69 parts;...

Abstract

A process for preparing the cerebroside compounds including beta-daucosterin from the root of flax includes such steps as extracting separation and recrystallizing.

Description

technical field [0001] The invention relates to a new method for preparing cerebroside compounds, namely extracting cerebroside compounds from flax. Background technique [0002] Flax (Linum usitatissimum L.) is a plant of the genus Linaceae, which is widely distributed all over the country. The plant is an annual herb with smooth stems and a plant height of 0.75-1.20m. There are branches at the top, which are umbrella-shaped; the cross-section of the stem is round and gray-green; the flax leaves are gray-green, alternate, with linear lanceolate edges, dense leaves, flat surface, 2-3.5cm long, 22cm wide ~4cm, the base of the leaf gradually narrows, blue-green; flowers are scattered on the top of the pedicel, the pedicel is erect, 2-7mm long, in racemes or open cymes; sepals are 5, narrow and long or long ovate, 5-7mm long , entire, without nectary glands, jagged edges, total sepals 1 / 2 of petals; petals blue, white or light red, about 1 cm long, obovate; stigma linear, ext...
