本文对爵床科的中草药穿心莲[Andrographis paniculata(Brum.f.) Nees],及同科的其他四种中草药——大青叶[马兰Strobilanthes cusia(Nees) O.Kuntze=Baphicanthus cusia(Nees) Bremek.]、化痰清[Dieliptera crinita(Thunb.) Nees]、瓦子草[爵床Rostellularia procumbens(L.)Nees=Justicia larocumbens L.]及红泽兰[日本马兰Strobilanthes japonicus(Thunb.) Miq.]花前期的茎、叶,进行了组织形态的比较观察。同时,我们对穿心莲的各个不同生长发育阶段的茎、叶进行了较系统的组织观察,证明构造各不相同。因此,可以根据组织构造判断其生长期,因为花前期的穿心莲叶、茎的有效成分含量最高。
This article discusses the Andrographis paniculata (Brum.f.) Nees, a Chinese herbal medicine of Aegilops edulis, and other four Chinese herbs of the same family, the Folium oleifera (Strobilanthes cusia (Nees) O.Kuntze=Baphicanthus cusia (Nees) Bremek. .], Huai Qingqing [Dieliptera crinita (Thunb.) Nees], Kaozi Cao (Fructus rostellularia procumbens (L.) Nees = Justicia larocumbens L.], and red silk orchid [Strobilanthes japonicus (Thunb.) Miq. ] The stems and leaves in the pre-flowering stage were observed for comparison of histological morphology. At the same time, we systematically observed the stems and leaves of different stages of growth and development of Andrographis paniculata and demonstrated that the structures are different. Therefore, the growth period can be judged based on the tissue structure, because the content of active ingredients of the leaves and stems of the pre-flowering period is the highest.
