Lespedeza is a herbaceous perennial plant with a woody short rhizome and direct pressing stems up to 50 cm tall.
The leaves are trifoliate, with filiform-needle stipules. The leaflets are oblong or oblong-elliptic, ending with spines.
The inflorescences are axillary racemes, flowers of moth type, yellowish or white with purple stripes.
The fruit is a single-seeded elliptical or rounded ovoid bean. It blooms in July and August, the fruits ripen in September.
Bicolour lespedeza is a shrub up to 1-1.5 m tall and up to 3 cm in diameter at the base of the stock.
The stems are strongly branched, with numerous thin twig-shaped branches, the ends of which annually freeze over even in the very south of Primorye. The leaves are trifoliate with small styloid stipules, the leaves are elliptical, rounded or oblong-elliptical, at the apex with a small notch and a thin spike. The young leaves are silky pubescent, the adult ones are with rare pressed white hairs.
The inflorescence is in the form of a pyramidal panicle of sparse spreading branches.
The flowers are of the moth type, with a red or pinkish-purple corolla, the end of which is always colored more intensely (hence the specific epithet is two-coloured).
The fruit is a flat, single-seeded bean with a pronounced network of veins.

It blooms in July – August.

Spreading. In Russia lespedeza is found in the south of Transbaikalia, in the Amur region and southern Primorye. In addition, there are isolated areas of the range in the Baikal region.Bicolour leaspedeza grows in Eastern Siberia and the Far East of Russia.

Habitat. Lespedeza grows on dry open or with rare bushes grassy slopes with stony ground, along the banks of rivers, on sandy-pebble and sandy valley sediments. The main areas of the raw material harvesting on an industrial scale are the southern areas of the Trans-Baikal Territory, the Amur Region and the Primorsky Territory.

Bicolour lespedeza occurs on edges, rocky cliffs, clearings, forming large thickets.


The chemical composition of lespedeza

In the herb of lespedeza there are found:

  • flavonoids (up to 2.5%) – kaempferol, quercetin, orientin, homoorientin, vitexin, saponaretin, bioquercetin, lespedin.
  • In addition, catechins and phenolcarboxylic acids were found.

Bicolour lespedeza shoots contain:

  • flavonoids – quercetin, kaempferol, lespanedin, isoquercitrin, orientin, etc.

Harvesting and storage of raw materials

Harvesting. The lespedeza herb is harvested by cutting the leafy part of the plant at about 5–10 cm above the soil surface with knives, sickles or pruners. The raw materials are examined to remove impurities from other plants. The bicolor lespendeza shoots are harvested, cutting off its tops with a length of 30 cm with knives or shears. It is necessary to remove impurities and lignify stems.

Drying. It is dried in well-ventilated attics or under sheds, laying them loosely on fabric or paper and stirring occasionally. The heat drying is allowed at a temperature of 40-50ºС.

Storage. The raw materials are stored in dry and well-ventilated areas on the shelves.
