![]() ![]() ![]() To prepare the dyestuff, the gromwell roots are softened overnight in 60° water and then pounded to release the dye. While this occurs, the silk is pre- mordanted the mordanting process involves repeated immersion of the cloth or yarn in the alum bath and drying over a two- or three-month period. The roots are collected and dried for two to three months to mature the color. The process of extracting purple dyestuff from the roots was an exceedingly long, complex and time-consuming process, necessitating its relatively high expense: īefore the introduction of synthetic dyes to Meiji period Japan, the roots were commonly used as a dyestuff for luxury textiles, typically high-end kimono and obi. It has been cultivated in Japan since the Nara period for its root, which can be used for herbal medicine and to make dyes. The enzyme geranylhydroquinone 3''-hydroxylase uses geranylhydroquinone, NADPH, H + and O 2 to produce 3-hydroxygeranylhydroquinone, NADP + and H 2O. This enzyme is involved in shikonin biosynthesis. Biosynthetically, alkannin is produced in plants from the intermediates 4-hydroxybenzoic acid and geranyl pyrophosphate. The enzyme 4-hydroxybenzoate geranyltransferase utilizes geranyl diphosphate and 4-hydroxybenzoate to produce 3-geranyl-4-hydroxybenzoate and diphosphate. The genome sequence of Lithospermum erythrorhizon is sequenced and has facilitated the discovery of a putative retrotransposition-derived duplication event that produced a 4-hydroxybenzoate geranyltransferase gene involved in alkannin biosynthesis. The dried root of Lithospermum erythrorhizon (lithospermum root or Lithospermi Radix) is a Chinese herbal medicine with various antiviral and biological activities, including inhibition of human immunodeficiency virus type 1 (HIV-1). It is called zǐcǎo ( 紫草) in Chinese, jichi ( 지치) in Korean, and murasaki ( ムラサキ 紫) in Japanese. Callicarpa dichotoma species is native to China, Japan, and Korea.Lithospermum erythrorhizon, commonly called purple gromwell, red stoneroot, red gromwell, red-root gromwell and redroot lithospermum, is a plant species in the genus Lithospermum.Callicarpa dichotoma species is invasive in Alabama.As an alternative, use Callicarpa americana (American Beautyberry).(15 cm) in late winter to early spring to encourage compactness and flowering. Best fruit production occurs when these Beautyberry shrubs are planted in groups or massed (better cross-pollination). Perfect also as a specimen plant or deciduous hedge or screen. ![]() Mass in mixed shrub borders, containers, and foundation plantings.Easy to grow and low maintenance, this plant is affected by very few pests and diseases.Winner of the Gold Medal award of The Pennsylvania Horticultural Society and GreatPlants award of the Nebraska Statewide Arboretum.Fairly adaptable to different soil types, but fertile soil with good drainage is preferred. Best flowering and fruit production occurs in full sun. A full sun to part shade lover, this plant is best grown in average, medium, well-drained soils.Grows with a dense mounding habit, at a moderate rate, up to 3-4 ft.Easy to grow, Callicarpa dichotoma species is native to China, Korea, and Japan. Adding rich color to the landscape, they make a lovely contrast with the foliage of elliptic green leaves that turns golden-yellow in fall. Attractive to bees and butterflies, they are abundantly followed by clusters of luminous lilac-violet fruits in late summer, which persist after the leaves have fallen and stand out beautifully. Elegant with its long, arching branches often kissing the ground at their tips in a cascading or weeping effect, Callicarpa dichotoma bears clusters of small, pink to lavender flowers along the stems in summer. One of the best ornamental fruiting shrubs, Callicarpa dichotoma (Purple Beautyberry) is a small, compact, rounded, deciduous shrub, primarily grown for its eye-catching display of purple berries from late summer through winter. ![]()
