Table 2: _Cont._The terpenoids group (39.51%) contribute the most aroma of the flower part in _H. cagayanensis_ with the metabolite \(\beta\)-ocimene (terpenoid) and methyl salicylate (benzenoid) with a relative percentage of 25.78% and 24.67%, respectively. On the other hand, the alcohols group (29.59%) was the most prominent in the _H. lacunose_, with 1-octen-3-ol metabolite dominating with relative percentages of 26.1%. Meanwhile, the ester group (55.45%) was found highest in _H.
