【目的】为区分榕树(Ficus microcarpa Linn.f.)和高山榕(F.altissima Bl.)气生根提供参考依据。【方法】采集新鲜榕树和高山榕的气生根作为样品,采用体视镜进行外观形态鉴别;采用显微镜对2种植物气生根根被表面、根尖横切面、根尖后部横切面以及粉末进行显微鉴别。【结果】外观形态鉴别:榕树气生根数目多于高山榕,直径小于高山榕;根尖及根尖后部横切面:初生木质部束不同,榕树为五至七原型,高山榕为七至十原型;粉末:榕树粉末为黄棕色,高山榕粉末为红棕色,高山榕纤维更多,直径更大,有簇晶排列成行。【结论】上述特征可较好地鉴别榕树和高山榕气生根,将为2种药材的鉴别及临床用药提供安全可靠的科学依据。
【Objective】 The purpose of this study is to provide references for distinguishing the aerial roots of Ficus microcarpa Linn.f. and F. altissima Bl. 【Method】 The aerial roots of fresh banyan and alpine banyan were taken as samples, and their morphological appearances were identified by using endoscopy. Microscopic examination was performed on the surface, apical cross-section, apical posterior cross-section and powder of the aerial roots of the two plants Microscopic identification. 【Result】 The morphological identification of appearance: the number of root bark was higher than that of alpine banyan and the diameter was smaller than that of alpine banyan. The cross section of apical and apical posterior was different: the xylem bundle was different, the banyan was five to seven prototypes, ; Powder: Banyan powder is yellow-brown, alpine banyan powder is reddish brown, Ficus altar more fibrous, larger diameter, with clusters arranged in rows. 【Conclusion】 The above characteristics can well identify the rooting of fig tree and alpine yung gas, which will provide a safe and reliable scientific basis for the identification and clinical application of 2 kinds of medicinal herbs.
