Color atlas of concentrated juice photograph determines the content of bolus of
From;    Author:Stand originally

Prescription of bolus of 6 flavour glutinous rehmannia is: 160g of ripe glutinous rehmannia, cornel (make) 80g, peony skin 60g, yam 80g, tuckahoe 60g, 60g of lustre have diarrhoea. 2005 edition " Chinese pharmacopoeia " used law of color atlas of concentrated juice photograph to determine the content of phenol of the root bark of the tree peony in Qian Gan of the horse in cornel and peony skin. The content that concerns preparation of bolus of 6 flavour glutinous rehmannia measures calm method to be summed up as follows.
One, 2005 " Chinese pharmacopoeia " content of bolus of 6 flavour glutinous rehmannia determines below:
Cornel:
Color atlas condition and systematic applicability experiment: Silica gel of bond of alkyl of 18 alkyl silicon is filler; With 4 hydrogen furan - second nitrile - methanol - solution of 0.05 % phosphoric acid (1: 8: 4: 87) for photograph of going from place to place; Detect wavelengh is 236nm, column is lukewarm 40 ℃ . Theory board counts the Qian Gan that press a horse peak plan should not under 4000.
Taste the preparation of solution for trying: Take bolus of this the honey that taste water or small sweet pill, mincing, take make an appointment with 0.7g, nicety says to decide; Or take weight difference to check a big sweet bolus below, cut broken, take make an appointment with 0.1g, nicety says to decide, buy provides taper of a place of strategic importance in bottle, nicety joins 25ml of 50 % methanol, fill in closely, say to decide weight, supersonic extraction (power 250W, frequency 33kH Z) 15 minutes, put cold, say to decide weight again, with 50 % methanol complemental reduce the weight that lose, shake up, filtration. Exact amount takes add filtrate 10ml, buy is neuter alumina column (200 eye of 100 ~ , 4g, internal diameter 1cm, dry method holds post) on, with 40 % methanol right amount liquefy, transfer to 10ml measuring flask in, add dilute of 50 % methanol to scale, shake up, get namely.
Peony skin
Color atlas condition and systematic applicability experiment: It is filler with silica gel of bond of alkyl of 18 alkyl silicon; With methanol - water (70: 30) for photograph of going from place to place; Detect wavelengh is 274nm. Theory board number presses phenol of the root bark of the tree peony peak plan should not under 3500.
Taste the preparation of solution for trying: Take bolus of this the honey that taste water or small sweet pill, mincing, take make an appointment with 0.3g, nicety says to decide; Or take weight difference to check a big sweet bolus below, cut broken, take make an appointment with 0.4g, nicety says to decide, buy provides taper of a place of strategic importance in bottle, nicety joins 50ml of 50 % methanol, fill in closely, say to decide weight, supersonic extraction (power 250W, frequency 33kH Z) 45 minutes, put cold, say to decide weight again, with 50 % methanol complemental reduce the weight that lose, shake up, filtration, take add filtrate, get namely.
