Three new iridoids named as pediverticilatasin A – C (1 – 3, resp.), together with five known iridoids (4 – 8, resp.) were isolated from the whole plants of Pedicularis verticillata. The structures of three new compounds were identified as (1S,7R)‐1‐ethoxy‐1,5,6,7‐tetrahydro‐7‐hydroxy‐7‐methylcyclopenta[c]pyran‐4(3H)‐one (1), (1S,4aS,7R,7aS)‐1‐ethoxy‐1,4a,5,6,7,7a‐hexahydro‐7‐hydroxy‐7‐methylcyclopenta[...
This research focus on developing approach to innovative design problems based on the TRIZ and extension method. The proposed innovative design procedure combines the Su-Field modeling procedure, extension method and Kano-based evaluation model to improve the efficiency and extent of concept evolutions. The extensibility of matter-element helps to transform the descriptions of design problems and...
This research tries to make use of extensibility of matter-element to transfer the descriptions of design problems and solutions into creative fields. By possessing a symbolic system and transformation rules, the Su-Field analysis model can assist designers to diagnose and solve most design problems. The concrete result includes, introducing concept extension of matter-element into symbolic developments...
