Overview
Areca Peel is the dried pericarp of the fruit of Areca catechu L. (Fam. Palmae). The unripe fruit is collected in winter to early spring, boiled and dried, longitudinally split into two halves, and the pericarp is peeled off, known as "Dafupi"; the ripe fruit is collected in late spring to early autumn, boiled and dried, the pericarp is peeled off, loosened, and dried in the sun, known as "Dafumao".
Description
###大腹皮 | Dafupi
It is slightly oval or oblong-shaped, measuring 4-7 cm in length, 2-3.5 cm in width, and 0.2-0.5 cm in thickness. The outer pericarp is dark brown to nearly black, with irregular longitudinal wrinkles and raised transverse ridges. The top has the remnants of the stigma, and the base has the fruit stalk and remnants of the calyx. The inner pericarp is concave, brown or dark brown, smooth, and hard-shelled. It is light in weight and hard in texture. When longitudinally torn, the fibrous middle pericarp can be seen. It has a slight odor and a slightly astringent taste.
###大腹毛 | Dafumao
It is slightly oval or gourd-shaped. The outer pericarp is mostly shed or remains. The middle pericarp is brown and hairy, yellowish-white or light brown, loose and soft in texture. The inner pericarp is hard-shelled, yellowish-brown or brown, with a smooth inner surface, and sometimes longitudinally cracked. It has a slight odor and a mild taste.
Identification
(1) The powder of Dafupi is yellowish-white or yellowish-brown. The fibres of the middle pericarp are bundled, slender, with a diameter of 8-15 μm, slightly lignified, and have obvious pits. The surrounding cells contain round clusters of silica, with a diameter of about 8 μm. The cells of the inner pericarp are irregularly polygonal, nearly circular, or elliptical, with a diameter of 48-88 μm, and have obvious pits.
(2) Take 5 g of the powder, add 50 ml of methanol, sonicate for 30 minutes, filter, evaporate the filtrate to dryness, dissolve the residue in 2 ml of methanol, filter, and continue to filter to obtain the test solution. Take 5 g of the reference drug Dafupi, prepare the reference drug solution using the same method. Carry out the method for thin layer chromatography<0502>, using silica gel G as the coating substance and a mixture of chloroform-methanol-formic acid (7:0.1:0.02) as the mobile phase. Apply separately to the plate 5 μl of each of the above two solutions. After developing and removal of the plate, dry in air. Spray with a 10% solution of sulfuric acid in ethanol, heat at 105°C to the spots clear. Examine under ultraviolet light at 365 nm. The fluorescent spot in the chromatogram obtained with the test solution corresponds in position and colour to the spot in the chromatogram obtained with the reference drug solution.
