Crude Drug Identification
Properties of Crude Drugs
1. Purple Jasmine Root: The root is oblong-conical or cylindrical in shape; some are flattened, and some have visible lateral roots. It measures 5–10 cm in length and 1.5–5 cm in diameter. The surface is grayish-yellow, with longitudinal wrinkles and traces of fibrous roots. There is a stem base scar at the apex. The texture is hard and difficult to break; the fracture surface is irregular, with visible annular rings. When steamed or boiled, the fracture surface becomes horn-like.Odorless, with a mild taste and a sensation of throat irritation.
2. Purple Jasmine Leaves: The leaves are mostly curled; when flattened, intact leaves are ovate or triangular, 4–10 cm long and approximately 4 cm wide. The apex is long and pointed, the base is wedge-shaped or heart-shaped, and the margins are slightly wavy. The upper surface is dark green, while the lower surface is grayish-green. The petioles are relatively long and covered with fine hairs. They have a faint odor and a sweet, neutral taste.
3. Purple Jasmine Seeds: The fruit is ovoid, 5–8 mm long and 5–8 mm in diameter. The surface is black, with five distinct ridges and covered with punctate protrusions; the inner surface is relatively smooth, with prominent ridges. There is a scar from the style at the apex and a scar from the fruit stalk at the base. The texture is hard. The seeds are yellowish-brown, with a well-developed endosperm that is white and mealy.

Purple jasmine (Jasminum purpureum), a plant of the genus Jasminum in the family Jasminaceae.
Morphological Characteristics
An annual or perennial herb, 50–100 cm tall. The root is robust, conical or spindle-shaped, fleshy, with a brownish-gray surface and a white, mealy interior. The stem is erect, highly branched, cylindrical, with swollen nodes.Leaves are opposite; long-petiolate, with lower petioles exceeding half the length of the leaf blade, while upper leaves are nearly sessile; leaf blades are papery, ovate or ovate-triangular, 3–10 cm long, 3–5 cm wide, with an acute apex, a truncate or slightly cordate base, and entire margins.Flowers number from 1 to several, terminal, arranged in a corymb; each flower has a calyx-like involucre at the base, green, 5-lobed; flowers are hermaphroditic, with a single perianth, red, pink, white, or yellow; the perianth tube is cylindrical, 4–5 cm long, expanding into a trumpet shape at the top, 5-lobed, and spreading;There are 5–6 stamens with slender filaments equal in length to or slightly longer than the perianth; there is a single pistil with a superior, ovoid ovary; the style is solitary, slender and linear, and the stigma is capitate and slightly lobed. The fruit is an achene, nearly spherical, about 8 mm long, black when ripe, finely ribbed, and enclosed by persistent bracts.

Distribution Area
Distributed throughout China.
Growth Habits
Prefers a warm and humid environment; grows best in partial shade and is not cold-tolerant. Not particular about soil type, but thrives best in fertile, deep sandy loam or oil-sand soil.
Propagation Methods
Propagation is by seed.
Cultivation Techniques
Harvest in batches 2–3 times during the fruit ripening period; after the final harvest, cut the fruit-bearing branches, thresh out the seeds, and sun-dry or air-dry them for later use. Sow in March–April; prepare 1.3-meter-wide raised beds, dig holes with 33 cm row and plant spacing, and sow 7–8 seeds per hole, using 15 kg of seed per hectare.Seedlings may also be raised and transplanted. Cultivate the soil and remove weeds three times: the first time after the seedlings have emerged uniformly, at which point thin and replant as needed, leaving 3–4 seedlings per hole; the second time in early summer; and the third time in late summer. After each cultivation, apply liquid manure made from human or animal waste as a top dressing.
