Icariin Powder is extracted from the dried leaves of the medicinal parts of Epimedium. So, why use leaves and not other parts? This article will introduce you to the reasons for extracting icariin from dried leaves.
1. Pharmacopoeia regulations
According to the latest regulations of "Chinese Pharmacopoeia(ChP)”, the medicinal parts of Epimedium have been changed from "dry aerial parts" to "dry leaves". And the extracts are derived from 5 kinds of Berberis plants, namely Epimedium brevicornu Maxim, Epimedium koreanum Nakai, Epimedium sagittatum (Sieb. et Zucc) Maxim ), Epimedium pubescens Maxim and Epimedium wushanense T. S. Ying. Since 2010, Wushan Epimedium has been included in the Pharmacopoeia as a single traditional Chinese medicine because of its great difference in chemical composition with other medicinal materials of Epimedium from several sources.
2. The highest content
Compared with Epimedium leaves, Epimedium stem and Epimedium petiole have fewer chromatographic peaks and smaller peak areas, indicating that these two parts of Epimedium contain less chemical substances. The number of chromatographic peaks in the chromatogram of Epimedium leaves was larger and the peak area was larger. This indicates that the leaf parts of Epimedium contain more abundant chemicals and higher content of active ingredients. One of the most abundant active ingredients in Epimedium leaves is icariin. The above test results show that the pharmacopoeia has a certain rationality for the medicinal parts of Epimedium to be "dried leaves".
Epimedium leaves are rich in chemical substances, especially the sum of the content of the index components stipulated in several pharmacopoeia can meet the standard requirements. This indicates that Epimedium leaves have certain medicinal development value. Qyherb extracts high quality and high purity Icariin Powder from selected raw materials of Epimedium leaves.
