Recently, we have found a significant variety in chemical composition of low-mass star forming regions. Although the hot core like chemistry producing complex organic molecules such as HCOOCH3 and C2H5CN has widely been recognized in low-mass star forming regions like IRAS16293-2422 and NGC1333IRAS4B, we have discovered a completely different case which shows extremely rich carbon-chain molecules such as CnH and HCnN. That is L1527 in Taurus. Rich carbon-chain molecules are regenerated in the vicinity of the protostar in L1527, triggered by the evaporation of the CH4 ice due to star formation activities. This is new carbon-chain chemistry (Warm Carbon-Chain Chemistry : WCCC) in contrast to the conventional and classical one which has long been applied to cold starless cores. The variation of chemical composition would originate from some differences in star formation processes, and its detailed understanding will provide us a new insight into 'variation' of star formation. In the present observation, we would like to find out the second or more example of this WCCC source in the southern star forming regions with MOPRA.
