The genus Iris (Iridaceae) comprises over 300 species, which is distributed mainly in the northern hemisphere. Iris germanica L., a perennial herb, is cultivated as an ornamental and aromatic plant in many areas of the world. The rhizomes of I. germanica are traditionally used in Pakistan for dropsy and gall bladder diseases, and as a diuretic, antispasmodic, stimulant, and aperient . Previous phytochemical investigations of the Iris plants have revealed a variety of compounds, including flavones, isoflavones and their glycosides, benzoquinones, triterpenoids, and stilbene glycosides [2, 3, 4, 5, 6]. In this study, nine alkaloid compounds were reported from the plant.
The rhizomes of Iris germanica L. were purchased from Qianxiang Town, Dongyang City, Zhejiang Province of China, in August 2010. The plant was identied by Prof. Minjian Qin, and a voucher specimen (No. Xie 2010001) was deposited in the Herbarium of Medicinal Plants of China Pharmaceutical University.
