Ipomoea purpurea, the common morning-glory, tall morning-glory, or purple morning glory, is a species in the genus Ipomoea, native to Mexico and Central America. Like all morning glories, the plant entwines itself around structures, growing to a height of 2–3 m (6 ft 7 in – 9 ft 10 in) tall. The leaves are heart-shaped and the stems are covered with brown hairs. The flowers are trumpet-shaped, predominantly blue to purple or white, and 3–6 cm (1.2–2.4 in) in diameter. The plant is predisposed to moist and rich soil, but can be found growing in a wide array of soil types. It is naturalized throughout warm temperate and subtropical regions of the world. Although it is often considered a noxious weed, I. purpurea is also grown for its attractive purple and white flowers, and has many cultivars. Common cultivars include I. purpurea ’Crimson Rambler’ (red-violet blossoms with white throats), ’Grandpa Ott’s’, ’Kniola’s Black Knight’, ’Star of Yelta’ (blossoms in varying shades of deep purple with white or pale pink throats), and ’Milky Way’ (white corolla with mauve accents). The triangular seeds have some history of use as a psychedelic; they, like I. tricolor, may contain LSA. Effects are reported to be somewhat similar to those of LSD. Acylated cyanidin glycosides can be isolated from violet-blue flowers of I. purpurea. These anthocyanins were all based on cyanidin 3-sophoroside-5-glucoside, acylated with caffeic acid and/or p-coumaric acid. Acylated pelargonidin glycosides can be isolated from the red-purple flowers of I. purpurea. The acylated anthocyanins were all based on pelargonidin 3-sophoroside-5-glucoside, acylated with caffeic acid and/or glucosylcaffeic acid. Commercial morning glory seeds are commonly treated with toxic methylmercury, which serves as a preservative and a cumulative neurotoxic poison that is considered useful by some to discourage their recreational use. The US has no legal requirement to disclose to buyers that seeds have been treated with a toxic heavy metal compound. According to the book Substances of Abuse, in addition to methylmercury, the seeds are commonly coated with a chemical that cannot be removed with washing that is designed to cause unpleasant physical symptoms, such as nausea and abdominal pain. The book states that this chemical is also tox Ipomoea purpurea，常见的牵牛花、高大的牵牛花或紫色牵牛花，是 Ipomoea 属的一个物种，原产于墨西哥和中美洲。 像所有牵牛花一样，植物缠绕在结构周围，长到 2-3 m（6 英尺 7 英寸 - 9 英尺 10 英寸）高。叶子是心形的，茎上覆盖着棕色的毛。花呈喇叭形，主要为蓝色至紫色或白色，直径为 3-6 厘米（ 英寸）。 该植物倾向于潮湿和肥沃的土壤，但可以在多种土壤类型中生长。它在世界暖温带和亚热带地区归化。虽然它通常被认为是一种有害杂草，但紫花紫花也因其迷人的紫色和白色花朵而种植，并且有许多栽培品种。常见的品种包括 I. purpurea ’Crimson Rambler’（红紫色花朵，白色喉咙），’Grandpa Ott’s’，’Kniola’s Black Knight’，’Star of Yelta’（深紫色不同深浅的花朵，白色或淡粉色的喉咙）和“银河系”（带有淡紫色口音的白色花冠）。 三角形种子有一些用作迷幻药的历史；它们和 I. tricolor 一样，可能含有 LSA。据报道，效果与 LSD 的效果有些相似。 酰化花青素苷可以从紫花紫蓝色花中分离出来。这些花青素均基于花青素 3-槐糖苷-5-葡萄糖苷，用咖啡酸和/或对香豆酸酰化。 酰化天竺葵苷可以从紫花紫红色的花中分离出来。酰化花青素均以天竺葵素3-槐糖苷-5-葡萄糖苷为基础，用咖啡酸和/或葡糖基咖啡酸酰化。 商业牵牛花种子通常用有毒的甲基汞处理，甲基汞作为防腐剂和累积的神经毒性毒药，被一些人认为可用于阻止其娱乐用途。美国没有法律要求向买家披露种子已经用有毒重金属化合物处理过的情况。根据《滥用物质》一书，除了甲基汞外，种子通常还涂有一种化学物质，这种化学物质无法通过洗涤去除，这种化学物质旨在引起令人不快的身体症状，例如恶心和腹痛。这本书说这种化学物质也是毒素 マルバアサガオ、一般的なアサガオ、背の高いアサガオ、または紫色のアサガオは、メキシコと中央アメリカに自生するサツマイモ属の種です。 すべてのアサガオのように、植物は構造物の周り&
