Quality Control Markers for Use in Herbs Authentication

As an increase in people’s awareness of health, traditional Chinese medicine, is becoming more popular to be adopted by many people especially Asians. Among many of the Chinese medicines, Tiepi Shihu (i.e. one of the types of Dendrobium) and Cordyceps Sinensis are two of the most expensive products. Dendrobium is one of the largest genera in the plant family Orchidaceae. More than 1,100 species of Dendrobium have been identified, with a wide distribution throughout Asia, Europe and Australia. Among them, Dendrobii Officinalis Caulis, known as Tiepi Shihu in Chinese, which is derived from dried stems of Dendrobium officinale Kimura et Migo, is traditionally recognised as the best Shihu for tonic purposes, such as nourishing the stomach, protecting the throat and benefiting eyes. The stems of Dendrobium officinale are always heated and then twisted into a spiral or springform followed by drying for sale in herbal markets under the name of Tiepi Fengdou. The uncharacteristic appearance and high price of Tiepi Fengdou could lead to the occurrence of adulterants, confusing species, and counterfeits. Therefore, authentication and quality evaluation of Tiepi Fengdou is crucial for ensuring safety and efficacy. One is the conventional method which greatly depends on the experience of botanical experts and subjective judgement while the other is based on DNA bio-coding, which is very expensive and time-consuming. As known in the industry, the existing methodologies are extremely intricate, difficult and time-consuming, and therefore not suitable for routine quality control. More importantly, they are not able to indicate whether the active ingredients exist in the samples. Some have tried to adopt other kinds of analytical methods including small molecule fingerprint and sugar composition analysis for quality control of Dendrobium officinale. However, these failed to distinguish Dendrobium officinale from other Dendrobium species. The key of this technology is to provide low cost, efficient, stable and convenient tool with reduced uncertainties in the qualitative and quantitative evaluation of Dendrobium officinale. The technology is now being adopted by the industry for both qualitative and quantitative authentication of herbal materials.
