| Abstract:

The Rosmarinus officinalis (Lamiaceae) known as Rusmari in Sanskrit which is a famous culinary herb known
for its healing properties like memory enhancing activity, indigestion , hepatoprotective , anticancer ,
antidandruff, antibacterial etc. As per Ayurveda energetics, the rasa of this plant is pungent and bitter, virya is
warm, vipaka is pungent , Guna is oily and light ,tissues enter is Plasma, blood, fat, muscle, nerve/bone marrow
and the other tropisms it can control is Head and Liver. In recent days the Rusmari gained global recognition
as an anticancer agent but most of the scientific validation is restricted only to cytotoxic effects. Hence the
current research is focused on molecular mechanism of secondary metabolites those are reported from the
Indian species of Rosmarinus officinalis against Human topoisomerases I & II using Libdock program in order to
know hypothetically which metabolite is acting as human topo- poison compared with positive drug
(camptothecin). The results are confirmed that secondary metabolites like homoplantaginin, Crismarin
showed high lib dock scores of 137.65, 138.94, 137.88 in compare to camptotechin with lib dock score of
104.72 and metabolites like Rosmarinic acid , Camphene, homoplantaginin showed highest C docker energies
with -56.63, - 44.90 and - 24.67 in compare to standard Doxorubicin with -33.33. All the rusmari metabolites
showed very good C docker interaction energy but with altered c dock energies. The current research laid a
platform towards the human dual topo poisoning activity of Rosemary drug leads and proved that Rusmari may
be an ideal anticancer library for dual topo poisoning drug leads and research is in progress.
