Identification of raw herbs
Character identification
Stem cylindrical, dark purple or gray-green surface, with vertical lines, smooth hairless, stems with thin hair; hard and brittle, easy to break, cross-section fiber, the central loose white pulp. Leaves alternate, with lower leaves with long stems, many deciduous, upper leaves sessile or subsessile; leaves more broken and shriveled, yellow-green above, below the light green, flattened oval, oblong or draped Needle-shaped, 4-10cm long, 1.5-4cm wide, apex pointed, acuminate or blunt, base narrowing and forming wing-like petiole, sharp edge serration, upper leaf serration more flow to the whole, with lashes. The head of inflorescence gathers on the top of the stem, arranged in a general or conical shape, and the sepals are three-layered. The membranous surface is present. The corolla is yellow, many fall off, and the crown is yellowish white and exposed. Gas fragrance, bitter taste. It is better to have more leaves and green color.
Microscopic identification
Leaf surface view: Peripheral wall of the lower epidermis is wavy and curved with a keratinous texture. The stomata is indeterminate and slightly sinks, with 3-5 secondary cells. The upper epidermal cell is polygonal, and the pericentral wall is slightly beaded and thickened, with a red horny texture and rare stomata. There are two types of non-glandular hairs; the non-glandular epidermis of the epidermis is composed of three cells, and the wall is thin. The top one cell often shrinks into rat tail and is smaller; the leaf margin consists of 3-5-7 cells and the wall thickness is slightly thicker. , 180-500μm long.
Tof(Time-of-flight), is JRT new product, which is a single-point LiDAR sensor. With a micro size of 46x17x7mm, customers can widely use in many Laser Measurement Solutions. The lidar distance sensor can measure 12m short-range. It's great for Unmanned Aerial Systems.Contact Us Now for data sheet.
