Constituents Mulberry Leaf contains flavonoids (e.g., rutin, quercetin 3-(6-malonyl) glucoside, isoquercitrin), alkaloids (e.g., 1-deoxynojirimycin), sterols, etc.
Description of the plant (Figs. 1a, 1b) Deciduoustree or shrub, 3 to 15(–20) m tall; stem erect, branched; young branch greenish, pubescent; mature branch greyish green with lenticels; lenticel prominent, reddish or yellowish brown; stem bark thin, rough, shallowly furrowed, grey, reddish or yellowish brown; bud ovoid, 4 to 6 mm long. Leaves simple, alternate, variable in size and shape, usually ovate to broadly ovate, (2.5–)5 to 20(–30) cm long, 2.5 to 14 cm wide, apex acute, acuminate or obtuse, base truncate, round or cordate, margin serrate, serrate-crenate, or irregularly lobed, basal nerves 3, blade abaxially glabrous or sparingly pubescent along major veins or tufted in axils of principle lateral veins and midrib, adaxially glabrous or sparsely pubescent; petiole up to 5.5 cm long; stipule ovate to lanceolate, 5 to 9 mm long, caducous. Inflorescence catkin, axillary, sordid white or greenish white, monoecious or dioecious; male catkin lax, 1 to 4 cm long; female catkin ovoid, 0.5 to 2 cm long; peduncle as long as the catkin. Male flower sessile; sepals 4, imbricate, ovoid, about 2.5 mm long, glabrous or hairy; stamens 4, filament inflexed in buds, anther globose to reniform, 2-loculed, papillose. Female flower sessile; sepals 4, imbricate, glabrous, marginally hairy; ovary 1-celled, glabrous, style, 0.5 to 1 mm long, 2-partite, stigma papillose. Fruit multiple, syncarpous, ovoid, ellipsoid or cylindric, 1 to 2.5 cm long, 0.5 to 1 cm wide, fleshy, becoming reddish, purplish, blackish or whitish when mature.

Microscopical (Figs. 2a, 2b, 2c) Transverse section of the leaf through the midrib and the lamina shows upper and lower epidermises, mesophyll, vascular tissue, and collenchyma. Upper epidermis, a layer of large rectangular cells; large lithocysts forming papillae, some of which boundary cells also contain cystoliths, covered with cuticle layer and unicellular trichomes. Mesophyll composed of a layer of palisade cells and layers of irregular spongy cells, xylem and phloem. Xylem composed of spiral and reticulate vessels. Collenchyma cells, located beneath upper and lower epidermises of the midrib. Lower epidermis, a layer of small oval cells; numerous anomocytic stomata, covered with cuticle layer and unicellular trichomes.
