Objective: To research the Araliaceae plant of Panax notoginseng flower

P. ginseng flower and P. quinquefolius flower by identifying their mini-characters

and provide scientific basis for the identification of mini-characters of this kind of medicinal materials. Method: Traditional Chinese medicine micro-macroscopical identification method was used to collect the information of the samples sold on the market by electronic eyepiece. Meanwhile

mini-characters of the P. notoginseng flower

P. ginseng flower and P. quinquefolius flower were identified by synthetic technique of Photoshop CS6 software. Then its surface mico-morphological characteristics were described

and finally

the key identification points were summed up. Result: The main distinguishing points of micro-trait included surface of peduncle

pedicel and pistil. The surface of the peduncle and pedicel of P. notoginseng flower had non-glandular hair and its pedicel surface white protrusion was arranged irregularly

and the separated P. notoginseng flower pistil stigma had brown yellow resin channel. P. ginseng flower peduncle and pedicel surface had no non-glandular hair and its frequently unseparated pistil stigma had unobvious yellow resin channel. The surface of the peduncle and pedicel of P. quinquefolius flower had non-glandular hair and its pedicel surface white protrusion was arranged regularly. The unseparated P. quinquefolius flower pistil stigma had no obvious resin channel. Conclusion: Through the micro-morphological identification method

we can clearly observe the surface features of them and the P. notoginseng flower

P. ginseng flower

P. quinquefolius flower can be distinguished effectively

providing the basis for the identification and quality evaluation of the P. ginseng flower.
