The research has been conducted to find out the best concentration of coconut water in the induction of roots of cuttings axillary buds Andrographis paniculata Nees. This research was conducted in Plant Physilogy of Division,   Department of Biology, Faculty of Math and Natural Science, AndalasUniversity, for 12 weeks.  The research used Completely Randomized Design. The material used was axillary buds  A.  paniculata  with nodal number 3. treated for 30 minutes in coconut water 10, 15 and 20% and aquadest as a controle each with 6 replications. Observations were done on live percentage, root length, root  numerous and  cuttings  height  after 12 weeks planting. The results showed that the  concentration 10 to 15% of coconut water was able with significant  to induce the  root growth of cutting axillary buds A. Paniculat.  The concentration 15% of coconut water was the best in inducing  cutting height growth, each with an average root length is 8.2 cm and the average number of roots that formed is 16, 0 and the average cutting height is  22.7 cm. There was an increase of average of  cuttings height growth by 86% which was supported by the average increase of root length and root number of 105.0% and 280.9% on the occasion of cuttings of axillary buds in coconut water concentration 15%.

The Morphology character and andrographolide quantification on Sambiloto (A. Paniculata) that growth in Sawah Dangka Jorong Gaduik, Tilatang Kamang, Agam (S 00o16159.311 E100o23110.311)  have been studied.  The Morphology character  of  A. Paniculata on generative fase  have been done in the field and Laboratorium of Biology Department, Andalas University. Quantification of  andrographolide constituen were analysed by using High Performance Liquid Chromatography (HPLC) in Chemical of Nature Resources Laboratorium, Pharmacy Faculty, Andalas University. The result showed that Morphology character of  Sambiloto ( A. Paniculata ) include parameters  ie. range of height plant ( 27-45 cm) ; range of nodus numerous ( 10-14 ); range of leaf-7 size (length; width)  ( 3.8-4.1 ; 0.8-1.1) cm; range of branch numerous ( 8-10), leaf dry weight rate  (2.482 g ), stem dry weight rate  ( 5.882 g ), and day old flowering rate  ( 110 day ). The Result of quantification secondary metabolite with high economic value, namely andrographolide showed respectively with level  2.208% (vegetative) and  2.780 % (generative).  Key Words : Andrographis paniculata, morpology chracter, andrographolide quantification  ABSTRAKTelah dilakukan studi tentang Karakter morfologi dan kuantifikasi senyawa andrografolide pada tanaman Sambiloto (A. Paniculata) yang hidup di Sawah Dangka Jorong Gaduik, Tilatang Kamang, Agam (S 00o16159.311 E100o23110.311). Karakter morfologi   A. Paniculata pada fase generative telah dilakukan di lapangan dan di  Laboratorium di Jurusan Biologi Universitas Andalas. Kuantifikasi senyawa andrografolid dianalisa dengan menggunakan High Performance Liquid Chromatography (HPLC) di Laboratorium Kimia Bahan Alam, Fakultas Farmasi Universitas Andalas.  Hasil menunjukkan bahwa karakter morfologi Sambiloto    ( A. Paniculata ) meliputi parameter  yaitu kisaran tinggi tanaman ( 27-45 cm) ; kisaran jumlah nodus ( 10-14 ); kisaran ukuran daunke-7  (panjang; lebar)  ( 3,8-4,1 ; 0,8-1,1) cm; kisaran jumlah cabang ( 8-10), rata-rata berat kering daun  (2,482 g ), rata-rata berat kering batang ( 5,882 g ), and rata-rata umur berbunga  ( 110 day ).  Hasil kuantifikasi metabolit sekunder dengan nilai ekonomi tinggi, yang dikenal sebagai senyawa andrografolid menunjukkan level   2,208%  (vegetatif) dan 2,780 % (generatif). Kata kunci: Andrographis paniculata, karakter morfologi, kuantifikasi andrografolid.
