The cut surface is grayish white ~ dark gray with layers of polygonal striations. The texture is hard.
It is odourless, and tastes very hot, paralyzing the tongue.

Identification Take 0.5 g of the pulverized Aconiti Ciliare Tuber, add 10 mL of dilute acetic acid, heat in a water bath with intermittently shakings, and filter off. To 5 mL of the filtrate, add one drop of the Meyer's reagent; the yellowish white precipitation is produced.

Purity Foreign matter No more than 3.0 % of stems should be obtained.

Loss on drying Not more than 12.0 %.

Ash Not more than 6.0 %.

Acid-insoluble ash Not more than 1.0 %.

Grade Good Aconiti Ciliare Tuber of good grade is fully-dried with strongly paralyzing taste on the tongue, and is of no stems and rootlets.

It is odourless, and tastes bitter, paralyzing the tongue tip.

Identification Take 0.5 g of the pulverized Aconiti Koreani Tuber, add 10 mL of dilute acetic acid, heat in a water bath with shaking, and filter off. To 5 mL of the filtrate, add the Meyer's reagent; the white precipitation forms.

ACORI GRAMINERI RHIZOMA


석창포

Acori Gramineri Rhizoma is the rhizome of Acorus gramineus Solander (Araceae).



Description Acori Gramineri Rhizoma is cylindrical, slightly compressed, often branched, 10 ~ 20 cm long, and 3 ~ 10 mm in diameter. The outer surface is yellowish brown ~ grayish brown with many internodes apart by 3 ~ 8 mm. The upper part of the rhizome is left with scars of leaf stalks, and the lower part is remained with scars of root hairs in a linear form. The texture is hard. The cross-sectional surface is pale yellow ~ white, and coarse with the distinct endodermis that separates the stele and the cortex layer. Under a microscope, on the cross-section, vascular bundles are scattered in the xylem and the cortex. In the stele, concentric vascular bundles are scattered, and in the cortex, collateral ones. The schizogenous intercellular space is developed well in the stele and the xylem. Starch particles are in the parenchyma cells.
It smells characteristic and tastes slightly bitter.

Purity Foreign matter No more than 5.0 % of the leaf stalks, the root hairs, sand and soil, and others should be obtained.

Loss on drying Not more than 13.0 %.

Ash Not more than 10.0 %.

Acid-insoluble ash Not more than 1.5 %.

Extract content Dilute ethanol-soluble extract: more than 5.0 %.

Grade Good Acori Gramineri Rhizoma of good grade is pale yellow on the outer surface and white on the cross-section. It should have strong aroma
